What You Need to Know About Marijuana and Your Fertility
I’ve been putting off writing this post for awhile now.
Mary Jane, weed, pot, reefer, Bobo bush, no matter what you call it, marijuana can be a very polarizing topic. And I tend to steer clear of controversy, at least in my online life.
When you talk about cannabis, folks tend to assume you’re a stoner. Add in my fro, fondness for boho fashion, and love of essential oils, and it’s easy for people to assume I must be. Which considering my license as a dietitian and legal status of marijuana where I live, would be a violation of the law and my code of ethics.
Truth be told, aside from the time in elementary school when my older friend (who had much older friends) rolled sugar, pepper, and dried grass from her backyard in a sheet of loose leaf paper and offered it to me as a makeshift dooby, I’ve never been offered a smoke of anything, nor have I ever smoked anything. But just because I choose not to, doesn’t mean I’m completely against others choosing to.
There are medically legitimate reasons to take it. And it’s the most used recreational drug in the US. Nearly half of the US population has tried it at least once. With more and more states decriminalizing its use, medical marijuana going mainstream (heck, even Whoopi Goldberg has medical cannabis line of products for menstrual issues), and Well + Good dubbing cannabis as one of THE wellness trends to watch in 2017, I’m sure its use is only going to continue to increase.
Before we get started, remember I’m not here to pass a moral judgment, I just want to provide you with the info. That way you can make a decision that’s right for you, your health, and your fertility.
That being said, I would be an awful healthcare practitioner if I didn’t say, the American College of Gynecologists strongly encourages women to avoid taking or using marijuana in all it’s forms while TTC, pregnant, or breastfeeding.
Ok, now that that’s out of the way, let’s jump in and answer your questions about fertility and marijuana.
What’s the difference between medical marijuana and recreational marijuana?
Medical marijuana is cannabis dispensed from medical dispensaries at the recommendation of a physician. Different strains are grown and recommended based on their unique cannabinoid content.
Cannabinoids are the naturally occurring chemicals in cannabis. They’re what give marijuana its medicinal properties. They’re the reason cannabis can dampen inflammation, kill bacteria, mellow out a stressed out mind, and soothe anxiety.
Each strain of medical marijuana has a unique composition, a special medley of natural chemicals that affect different body systems in different ways. This makes each strain especially effective for specific concerns.
Medical marijuana is also significantly lower in THC, the cannabinoid which makes recreational marijuana so alluring. THC is what causes the high feeling recreational users seek. So, no, medical marijuana won’t get you high.
Recreational marijuana can legally be purchased or grown in a handful of states. In those states, there are recreational marijuana stores you can purchase weed from. In states where recreational use has not been legalized, many people still grow, sell, and buy marijuana, but they do so illegally.
Recreational marijuana’s THC levels are significantly higher than what you’ll find in medical varieties, giving them exaggerated psychoactive properties. Plus, if you purchase pot from any place other than a dispensary or store, you really can’t ensure purity. That’s because it’s pretty common for sellers to mix in additives. And those additives can have unpredictable and dangerous side effects.
What diseases and conditions are medical marijuana recommended for?
Every state which allows the medical use of marijuana has different qualifying conditions. Below, you’ll find a list of qualifying conditions from all the states with legislation allowing for the use of medical marijuana. For information about your specific state, click this link.
Cannabinoid-deficient Benin republic hemp (Cannabis sativa L.) improves semen parameters by reducing prolactin and enhancing anti-oxidant status
Nigerian Cannabis sativa (hemp) causes male gonadotoxicity by inducing hyperprolactinemia, down-regulation of hypothalamic-pituitary-testicular axis, and oxidative stress. Benin republic hemp has been preferred by illicit users in Nigeria but its effect on male fertility is not understood. This study determined and compared the compositions of Benin republic hemp ethanol extract (BHE) and Nigerian hemp. The effects of BHE on semen parameters, reproductive hormones, and anti-oxidant status, and the possibility of bromocriptine (prolactin inhibitor) to abolish hemp-induced toxicities in rats were also investigated.
Thirty-six male Wistar rats were blindly randomized into 6 oral treatment groups (n = 6 each). Groups I (control) and II received normal saline and bromocriptine (3 mg/kg) respectively. Groups III and IV received 2 mg/kg of BHE alone and in combination with bromocriptine respectively, while groups V and VI received 10 mg/kg BHE alone and in combination with bromocriptine respectively. Comparisons among the groups were done by one-way analysis of variance, followed by post-hoc Tukey multiple comparison test. Statistical significance was considered at p < 0.05.
The BHE has no cannabichromene and tetrahydrocannabinol but a very small quantity of cannabinol and higher quantity of fatty acids when compared to Nigerian hemp. Both doses of BHE increased sperm count, morphology and viability but not motility. Co-administration of BHE with bromocriptine lowered sperm count but increased sperm morphology and viability. Bromocriptine and/or BHE caused reduction in the plasma prolactin level, increase in the plasma superoxide dismutase activity, but no significant change in the plasma gonadotropin releasing hormone, follicle stimulating hormone (except for the increase in rats that received bromocriptine+ 10 mg/kg BHE), luteinizing hormone, estradiol, malondialdehyde and glutathione peroxidase. The 10 mg/kg BHE or bromocriptine+BHE (both doses) increased total anti-oxidant capacity and catalase.
The BHE improves semen parameters by reducing plasma prolactin and enhancing plasma anti-oxidant status. Its pro-fertility potential might be associated with its deficiency in the widely known gonadotoxic phytocannabinoids.
Cannabis sativa (hemp), the most widely abused recreational drug worldwide , is becoming globally legalized due to its medicinal use by patients with epilepsy , inflammation , cancer , pain , etc. Furthermore, many synthetic compounds that act on the endocannabinoid system have been extensively studied in recent years [6,7,8]. However, its detrimental effects on the male reproductive functions have been well-established. For instance, it has been reported to decrease semen parameters [9,10,11], germ cell proliferation and reproductive organ weight [10, 12]. Mechanisms including hyperprolactinemia , down-regulation of hypothalamic-pituitary-testicular (HPT) axis [13, 14], endocrine disruption, and oxidative stress  have been implicated in hemp-induced gonadotoxicity.
Hyperprolactinemia has been reported to have a definite role in male infertility. It causes infertility in about 11% of oligospermic males  by inhibiting gonadotropin releasing hormone (GnRH) pulsatile secretion, which impliedly decreases gonadotropins (luteinizing hormone [LH] and follicle stimulating hormone [FSH]) and testosterone secretion. This prolactin-induced down-regulation of HPT axis ultimately leads to spermatogenic arrest, altered sperm quality, impaired sperm motility, and later produces secondary hypogonadism and male infertility. In addition to this indirect effect, hyperprolactinemia also directly influences steroidogenesis and spermatogenesis by acting on prolactin receptors present in Leydig and Sertoli cells in the testes to produce primary hypogonadism and male infertility .
There have been evidences that the hyperprolactinemia-induced infertility is reversible [15,16,17,18]. A simple medication like bromocriptine or cabergoline, which normalizes serum prolactin levels, has been consistently shown to restore gonadal functions, reverse infertility caused by hyperprolactinemia, and reduces prolactinoma size in majority of patients [17,18,19]. Thus, we also speculated that the hemp-induced gonadotoxicity mediated through hyperprolactinemia and down-regulation of HPT axis  might be reversed or prevented by inhibiting endogenous prolactin secretion with bromocriptine.
The National Drug Law Enforcement Agency (NDLEA) of Nigeria, through series of online and print media publications, has recently observed that most of the illegal hemp users in Nigeria have been preferentially obtaining hemp from Benin republic. The NDLEA also observed that users now compress this imported hemp and soak it with ethanol prior to its use; and that the “high” and euphoria felt by users of Nigerian and Benin republic hemp are comparatively different. It is not yet known whether there is difference in the quality of both hemp samples or not. The present study determined and compared the compositions of Benin republic hemp ethanol extract (BHE) and Nigerian hemps.
The effects of BHE on semen parameters, reproductive hormones, and anti-oxidant status were also investigated in rats. Bearing the prolactin-mediated gonadotoxic effect of Nigerian hemp  in mind, we further investigated if inhibition of prolactin with bromocriptine could abolish hemp-induced toxicities.
Thirty-six (36) adult male Wistar rats (weight range: 160–180 g) were obtained from the Department of Biochemistry, University of Ilorin, Nigeria. They were housed in wooden cages maintained under standardized conditions (12-h light/dark cycle, 27–30 °C, 50–80% relative humidity), and were acclimatized in the laboratory for 2 weeks before the commencement of the study. The rats were fed with standard pelletized rodent diet (Ace Feeds, Ibadan, Nigeria) and water ad libitum. All the animals were well-catered for according to the criteria outlined in the ‘Guide for the Care and Use of Laboratory Animals’ prepared by the National Academy of Science and approved by the Ethical Research Committee of the University of Ilorin, Nigeria.
Extraction and GC-MS analyses of hemp samples
Mixture of hemp seeds and leaves (75%:15% respectively), both of Benin republic and Nigeria origin, were kindly donated by the National Drug Law Enforcement Agency (NDLEA), Nigeria, for research purpose only. About 200 g of each of these samples was subjected to extraction with 98% ethanol in Soxhlet apparatus for 4–8 h as described earlier . The extract was evaporated to dryness in a rotary evaporator under vacuum to get the oil.
A gas chromatography (GC) from AgilentCo. USA, hyphenated to a mass spectrometer (MS, 5975C) with triple axis detector equipped with an auto-injector (10 μl syringe) was used. Helium gas was used as a carrier gas. All chromatographic separation was performed on capillary column having the following specifications: length- 30 m, internal diameter- 0.25 μm, thickness- 250 μm, treated with phenylmethylsilox. Other gas chromatography mass spectrometry (GC-MS) conditions are: ion source temperature (EI)- 250 °C, interface temperature- 300 °C, pressure- 16.2 psi, cut time- 1.8 min, 1.0 μL injector in splitless mode with split ratio 1:50 and injection temperature of 300 °C. The column temperature started at 35 °C for 5 min and changed to 150 °C at the rate of 4 °C/min for 2 min. The temperature was raised to 250 °C at the rate of 20 °C/min and held for 5 min.
The MS scanning was performed from M/Z85 to M/Z380. The GC-MS solution software provided by supplier was used to control the system and to acquire the data. The separation of the injected samples was carried out on an HP capillary column (HP-5MS). Identification of the compounds was carried out by comparing the mass spectra obtained with those of the standard mass spectra from National Institute for Standards and Technology (NIST) library (NIST II). Identification was based on the molecular structure, molecular mass and calculated fragments. The fatty acids and other organic compounds were identified by comparing their retention times with those of the standards. The quantity of each compound present was expressed as percentage of the total compounds.
Since the hemp sample of Nigerian origin has been repeatedly used in the series of our previous studies [10, 11, 13], we did not repeat its administration in this study, but only compared its composition with that of Benin republic. The 36 rats were blindly randomized into 6 groups (n = 6 per group). Groups I (control) and II received normal saline and bromocriptine (3 mg/kg) respectively. Groups III and IV received 2 mg/kg of BHE [10, 11] alone and in combination with bromocriptine  respectively, while groups V and VI received 10 mg/kg BHE  alone and in combination with bromocriptine respectively. All treatments were given once daily for a period of 30 days between 8:00 am to 10:00 am via oral gavage.
Animals were anaesthetized a day after the last treatment with sodium pentobarbital (40 mg/kg body weight, im). Thereafter, they were dissected in order to collect blood by cardiac puncture. Whole blood for the determination of the biochemical markers were collected in heparinized sample bottles which were centrifuged at 3500 rpm for about 10 min at -4 °C using a cold centrifuge (Model 8881, manufacturer: Centurion Scientific Ltd., United Kingdom). The separated plasma samples were collected into separate plain bottles and were stored at -20 °C prior to the biochemical analyses.
Determination of semen parameters
The procedure for determination of epididymal sperm parameters, such as; count, motility, morphology, and viability are summarized below as previously described [23, 24],
The testes from each rat were carefully exposed and one of them was removed together with its epididymis. For each separated epididymis, the caudal part was removed and placed in a beaker containing 1 ml of normal saline solution. It was macerated with a pair of sharp scissors and left for few minutes to liberate the sperm cells into the normal saline. Semen drops were placed on a clean grease-free glass slide and two drops of warm 2.9% sodium citrate were added. The improved Neubauer counting chamber was charged with the semen solution and the number of sperm cells, appearing as black dots, was counted in 25 small squares within the central counting area of the counting chamber.
The sperm suspension was diluted in 1 ml of normal saline solution. About 10 L was pipetted onto a clean grease free glass slide. A cover slip was lowered onto the sample on the slide, avoiding air bubbles, and the slide was examined using a microscope with a 40X objective. At least, six widely spaced fields were examined to provide an estimate of the percentage of the progressively motile sperm cells. The sperm cells with progressive motility were estimated and recorded as (N) while the total number of all the sperm cells counted was recorded as (T). Sperm motility (%) was calculated using (N/T × 100%).
The principle for determination of sperm morphology was based on the ability of morphologically normal sperm to appear white in color as the plasma membrane will prevent the dye to enter, while abnormal sperms take up the dye and stain dark color. The microscope slides and the eosin stain were pre-warmed to room temperature. One milliliter of the sperm suspension – normal saline solution was transferred to a test tube and 2 drops of 1% eosin were added and mixed gently for agitation. This was incubated for 45–60 min to allow its proper staining and then re-suspended with a Pasteur pipette. A clean grease-free glass slide was used. Potential damage to the sperm cells should be avoided. One or 2 drops of the stained sperm were placed approximately 1 cm from the end of the slide lying on a flat surface. A second slide was held with the slide’s long edge gently touching across the width of the sperm slide and pulled across to produce a sperm smear. After air-drying the slide, using a microscope at 100X objective, the sperm cells were examined. The sperm along the periphery was normally excluded from the examination because there is a greater tendency for artifacts to occur in these regions. At least, five fields were viewed covering the whole slide. Examples of morphological abnormalities are double-headed, elongated head, pyriform head, bent head, bent tail, bent mid-piece, coiled tail, double tail, headless, tailless, etc. All those with normal morphology were recorded as N while the total number of the counted spermatozoa was recorded as T. The percentage sperm morphology was calculated as (N/T × 100%).
Determination of biochemical parameters
Diagnostic kits for the determination of malondialdehyde (MDA), total anti-oxidant capacity (TAC), superoxide dismutase (SOD), glutathione Peroxidase (GPx), and catalase were obtained from Fortress Diagnostics Limited, United Kingdom. In addition, analytic kits for the determination of GnRH, prolactin, FSH, LH, testosterone, and estradiol were procured from Elabscience Biotechnology Company Ltd. Wuhan, Hubei, China. The analyses were done with spectrophotometer (Spectramax Plus; Molecular Devices, Sunnyvale, CA, USA) according to the manufacturers’ instructions.
Statistical analyses were done using statistical package for social sciences (SPSS) version 16.0 (IBM Corporation, Armonk, NY). Values were expressed as Mean ± S.E.M. of the variables measured. Comparisons among the groups were done by one-way analysis of variance (ANOVA), followed by post-hoc Tukey multiple comparison test. Statistical significance was considered at p < 0.05
Organic compositions of hemp samples identified by GC-MS
The BHE is rich in stearic acid (27.98%), followed by benzoic acid (14.43%), oleic acid (11.51%), benzeneacetic acid (10.72%), and benzophenone azine (9.96%). It has intermediate quantity of aniline (3.18%), cyclohexanecarboxylic acid (4.75%), and stearic glycidol (3.81%) but lower quantity of 2,3,4- Trimethoxyphenylethylamine (0.35%), Benzamide (0.29%), palmitic acid (1.09%), and cannabinol (1.20%). The acetone fraction from the ethanol extract of Nigerian hemp has its highest constituent as cannabinol (36.5%), followed by tetrahydrocannabinol (THC, 19.81%), α-linolenic acid (12.13%), palmitic acid (8.91%), oleic acid (5.94%), linoleic acid (4.87%), cannabichromene (1.7%), and stearic acid (1.42%). However, the n-hexane fraction from the ethanol extract of Nigerian hemp has its highest constituent as THC (49.11%), followed by cannabinol (20.25%), cannabichromene (5.58%), and linoleic acid (4.31%) (Table 1).
Effects of bromocriptine and/or BHE on semen parameters
Bromocriptine-treated rats had higher sperm count but unchanged sperm motility, morphology and viability when compared to control. Both doses of BHE increased the sperm count, morphology and viability but not sperm motility when compared to control. Rats that were co-administered with either dose of BHE and bromocriptine had lower sperm count but higher sperm morphology and viability when compared to rats that received bromocriptine alone (Fig. 1a-d).

Effects of bromocriptine and/or BHE on reproductive hormones
Treatment of rats with bromocriptine and/or BHE caused reduction in the plasma prolactin level but no significant change in the plasma GnRH, FSH, LH and estradiol (except for the significant increase in FSH of rats that were co-administered with bromocriptine and 10 mg/kg BHE) when compared to control. Neither bromocriptine nor any of the doses of BHE affected the plasma testosterone, but their co-administration significantly increased the plasma testosterone level (Table 2).
Effects of bromocriptine and/or BHE on lipid peroxidation and anti-oxidant status
Treatment of rats with bromocriptine and/or BHE caused increase in the plasma SOD activity but no significant change in the plasma MDA and GPx when compared to control. Rats that received 10 mg/kg of BHE and those that received combination bromocriptine and either dose of BHE had higher TAC and catalase when compared to control (Fig. 2a-e).

Hemp seeds have been developed into numerous products for food, cosmetic, therapeutic, functional food and nutraceutical industries . The presence of polyunsaturated fatty acids (PUFAs) in hemp seed oil has been extensively documented. It contains α-linolenic acid (omega-3 PUFA) and linoleic acid (omega-6 PUFA), both of which are essential fatty acids required to prevent cardio-metabolic disease . It also contains γ-linolenic acid, which makes it as an ideal ingredient for cosmetics (lipid-enriched creams, light body oils, etc.) . Though the present study did not identify PUFAs (α-linolenic and linoleic acids) in BHE as reported by authors that analyzed hemp from other sources , we however observed that it is a rich source of saturated (palmitic and stearic acids) and monounsaturated (oleic acid) fatty acids .
Because about 35% of the available oil has been reported to remain in the seed cake following pressing process while supercritical carbon dioxide extraction has been documented as a better alternative to pressing or organic solvent methods for extraction of lipids such as PUFAs from fish lipids and vegetable oils [28, 29], the discrepancy in the identified constituents might be thought to result from different methods of extraction: we used solvent extraction while Da Porto et al.  used supercritical carbon dioxide. However, this possibility is annulled by their previous observation that there was no difference between the fatty acid composition obtained from hempseed oil following Soxhlet apparatus or by supercritical carbon dioxide method of extraction .
We have consistently shown that ethanol extract of hemp leaves of Nigeria origin causes gonadotoxicity in male rats by eliciting hyperprolactinemia, down-regulation of HPT axis, oxidative stress, and endocrine disruption [10, 11, 13]. The improvement in semen parameters by BHE in this study is contrary to our previous reports and expectation, and thus of great surprise and interest to us. Because environmental variables of the soil at different location have been known to affect plant species composition and richness , we speculate that the discrepancy in our previous and current findings could result from different origins of the hemp samples used in both studies. We queried this speculation further by determining the GC-MS composition of acetone and n-hexane fractions of the ethanol extract of Nigerian hemp used for our previous studies. We confirmed the presence of α-linolenic acid in the acetone fraction only, but linoleic acid in both fractions. Furthermore, both fractions have cannabinoids including cannabichromene, THC, and cannabinol. It is interestingly worthy of note that these cannabinoids accounts for about 58% of the total composition of the acetone fraction but 75% of the n-hexane fraction of the Nigerian hemp. However, the BHE contains only cannabinol at very negligible quantity (1.2%) but no cannabichromene and tetrahydrocannabinol. Because both hemp samples from these two different locations gave varying GC-MS composition despite the same extraction method (using Soxhlet apparatus), it could be opined that the discrepancy in the composition is not related to the methods of extraction but related to the climatic difference of the origin of both hemp samples.
The beneficial effect of lipids on semen parameters has been well-documented. Cholesterol has been reported to increase cell membrane stability and decrease the transition temperature from the fluid to the gelatinous phase . Phospholipids also contribute to membrane permeability and flexibility, and cell functionality. Because the cholesterol to phospholipids proportion cannot be altered in sperm due to its dependence on species’ genetic factor , addition of PUFAs to diets has been suggested in order to increase its proportion relative to sperm membrane phospholipids and improve its fluidity and resistance to thermal stress . Moreover, dietary fatty acids supplementation has been reported to improve the cryopreserved stallion semen . We have also shown in the very recent publication from our laboratory that fatty acids could be responsible for the spermatoprotective effect of Telfairia occidentalis leaves in rats . On the contrary, THC (the psychoactive cannabinoid in hemp) has been consistently shown to inhibit motility, capacitation and acrosome reaction of human and boar spermatozoa through cannabinoid receptors 1 and 2 [12, 36,37,38]. We have also recently observed that THC inhibits the hyper-activated motility of capacitated rat sperms by reducing sperm velocities (average path, curvilinear, and straight-line), amplitude of lateral head displacement, and beat cross frequency . The improvement in semen parameters by BHE could thus be partly associated with its fatty acid constituents and its comparative deficiency in cannabinoids, while the abundant proportion of cannabinoids in Nigerian hemp could have superimposed its fatty acids and lead to gonadotoxicity as previously reported by us [10, 11, 13].
The release of prolactin from adenohypophysis is under tonic inhibition of dopamine, which is delivered to adenohypophysis from the hypothalamus via the hypothalamic-hypophyseal portal system. Dopamine decreases prolactin secretion by binding to the dopamine D2 receptors on the surface of lactotroph and diminishing intracellular cyclic adenosine monophosphate (cAMP) level. We have previously shown that increase in the plasma prolactin level is one of the mechanisms through which Nigerian hemp induces male gonadotoxicity . Therefore, it was tempting to investigate the role of prolactin in the improvement of semen parameters elicited by Benin republic hemp. Bromocriptine is a dopamine agonist that has been used for the treatment of hyperprolactinemia. Administration of bromocriptine alone increased sperm count but did not significantly affect other semen parameters. However, it synergizes with hemp extract to enhance sperm morphology and viability (though there were decreases in sperm count), which tends to involve the FSH and testosterone. Moreover, the plasma level of prolactin was decreased by both doses of the hemp extract and/or bromocriptine, while there were no significant changes in the plasma GnRH, gonadotropins (FSH and LH), and testosterone in hemp-treated rats. Similarly, previous studies have reported normal serum levels of gonadotropins but elevated serum prolactin in azoospermic or oligospermic patients, providing evidence for the sole role of prolactin on spermatogenesis independent of gonadotropins [15, 16]. Our current data also suggest that the pro-fertility potential of Benin republic hemp is partly mediated through inhibition of endogenous prolactin but independent of HPT axis. This is different from the Nigerian hemp that induces gonadotoxicity through hyperprolactinemia and down regulation of HPT axis .
Apart from hyperprolactinemia and down-regulation of HPT axis, we have further previously shown that the gonadotoxic effect of Nigerian hemp is also mediated through oxidative stress [10, 11]. In the current study, we investigated if the pro-fertility effect of Benin republic hemp will be related to an enhanced plasma anti-oxidant status. We observed that the hemp extract enhanced the TAC, which is accounted for by SOD and catalase but not GPx. This agrees with a previous study that observed that hemp seed oil has free radical scavenging potential even more than olive oil . Moreover, there was no lipid peroxidation in any of the experimental groups. Like the pattern observed for the sperm morphology and viability, there was a synergistic relationship between bromocriptine and hemp extract to enhance the plasma anti-oxidant status.
In conclusion, this study shows that hemp sample from Benin republic is deficient in cannabinoids. It also shows that this hemp sample improves semen parameters by reducing plasma prolactin and enhancing plasma anti-oxidant status. It was opined that the pro-fertility effect of the Benin republic hemp sample could be due to its deficiency in the widely known gonadotoxic cannabinoids. This study has cautioned us from making a generalized claim that hemp is gonadotoxic. It shows that the origin of hemp samples might determine their composition and their ethno-pharmacological effects on the body functions.
