Three Ways Marijuana Can Affect Fertility

Some studies show that marijuana use negatively affects fertility in men and women. Many articles and physicians advise against using marijuana while trying to get pregnant to reduce the risks of infertility. Learn more about the warnings signs of infertility and discover how you can develop healthy habits to increase your chances of getting pregnant.

1. Ovulation delay

Scientists aren’t sure exactly how THC affects the sexual function of women attempting to get pregnant. THC affects the hypothalamic-pituitary-gonadal (HPG) axis, which controls how your sex hormones interact. Continuous exposure to THC can inhibit the secretion of luteinizing hormone and prolactin from the pituitary gland in males and females. These hormones influence your chances of getting pregnant.

In women, high THC doses interfere with the menstrual cycle and may delay or prevent ovulation. Cannabinoids inhibit the activity of the HPG axis, meaning that marijuana use decreases the production of several hormones and can inhibit sexual behavior — if your sex drive is down, this can also hinder your efforts to conceive.

Regular smokers may have an elevated risk of not ovulating at all. A 2016 report also suggests marijuana disrupts the menstrual cycle and can lead to anovulatory cycles (cycles without ovulation).

In general, it’s thought that marijuana can affect the production of luteinizing hormone in women. LH regulates testosterone production in men and stimulates female ovulation. When men smoke frequently, they tend to have lower levels of testosterone, and women who smoke frequently have less LH.

In addition to marijuana use, it’s important to examine other causes of late ovulation so you can put yourself in the best position for a successful pregnancy.

2. Lower sperm count

According to the Mayo Clinic, marijuana use can impair a man’s sperm count and ability to reproduce. Other research has suggested that marijuana is bad for men’s fertility.

However, a Harvard study surprisingly refutes those findings and states that there’s no evidence of harmful effects on fertility. In the study, researchers collected blood samples and semen from hundreds of volunteers at the Massachusetts General Hospital fertility clinic. In the study, which ran from 2000 to 2017, men were asked about their marijuana use. The results showed no correlation between marijuana use and male fertility.

Since there isn’t a conclusive determination on the subject, if you have a male partner who smokes, try to discourage him from doing so while you are trying to conceive — especially if his sperm count is low.

3. Deterioration of existing fertility problems

There’s no conclusive evidence that marijuana use causes infertility, but research has found that it can lower sperm count, increase anovulatory cycles, and disrupt the balance of hormones in the body that encourage pregnancy.

Does smoking weed seeds make you sterile

As a teen me and my friends would smoke weed after school. Sometimes we would get some of the seediest weed around and you would get seed in your smoke no matter what. My friend would say smoking seeds makes you sterile. He would say I’m going to smoke seed all the time. I always thought it was B.S. So at work we start talking about kids somehow. This guy has just moved to my state says I don’t have kids I smoke seeds every once in awhile. That was weird cuz this guy is from far away. As an adult I smoke good weed with no seeds and have a couple of rug rats. Has anyone else heard of this or is it B.S.

Yes. But only if you smoke the seeds and stems. And only certain types of seeds. The ones with 6 stripes will make you very sterile.

5 stripes or less and you’re just ‘clean’, anything over 6 stripes and sterility has been achieved.

But beware of the dreaded eleven stripe pheno, very dangerous, approach cautiously.

Effects of Cannabis on the Male and Female Reproductive System, and Fertility

Use of cannabis may affect human fertility, depending on gender, general health, socioeconomic status and several other factors. Here, we look at existing research on cannabis and human fertility, in order to provide readers with an accurate, up-to-date summary of the current state of scientific knowledge.

To understand how cannabis may affect fertility, we must understand the effect it has specifically on males and on females. We’ll start by looking at the effects on the male reproductive system, and then focus on the more complicated effects on female fertility.

Cannabis use and male fertility

Some studies on the effect of cannabis use on male fertility have indicated that regular use may reduce spermatogenesis (the production of sperm in the testes) and testosterone levels.

In 2012, the American Society of Andrology published a review of research on the effects of illicit drug use on male fertility. The researchers found that in the majority of studies, it was consistently concluded that cannabis use had a negative impact on male reproductive physiology.

Another study in 1992 (Vescovi et al.) found that levels of luteinizing hormone(LH), an important pituitary gland hormone involved in reproductive function, were reduced in male chronic cannabis users compared to a non-cannabis-using, age-matched control group. A previous 1986 study (Cone et al.) also found a significant reduction in LH levels immediately after smoking cannabis.

And an even earlier study (Kolodny et al, 1974) into testosterone levels in “chronic” cannabis users found that 6 of 17 subjects had oligospermia (low sperm count), and that average testosterone levels in the cannabis-using group were just over half that of the control group. The effect of cannabis on testosterone levels was observed to be dose-dependent.

The endocannabinoid system and male fertility

Clearly, the endocannabinoid system has a role to play in the regulation of processes critical to male reproductive health, such as sperm count, testosterone levels, and levels of other key hormones such as LH.

For healthy adult males, it seems that use of THC does indeed cause some negative effects on fertility, which tend to increase with higher doses. However, THC’s endogenous analogue anandamide appears to be critical to the functioning of the male reproductive system.

The 2002 study found that sperm cells would bind to the agonist CP-55,940, demonstrating the presence of CB1-receptors. The study also concluded that the presence of THC and a synthetic anandamide analogue, AM-356, both reduced sperm motility in vitro. Interestingly, it was found that AM-356 exerted a biphasic dose-dependent effect on sperm motility, causing inhibition at high doses but hyperactivity at low doses.

Anandamide and the “capacitation” of human sperm cells

In a 1994 study, it was found that mammalian sperm, including that of humans, is actually incapable of fertilizing oocytes (eggs) immediately after leaving the testes. It requires a period of exposure to certain crucial hormones, enzymes and proteins on its journey through the vas deferens and ejaculatory ducts of the male reproductive system (as well as the reproductive fluids of the female vagina and oviducts) before becoming “capacitated” and able to fertilize an egg.

The 2002 study provides strong evidence that the presence of the anandamide in the seminal fluid, and its ability to bind to the CB1-receptors of the spermatozoa, are key to the “capacitation” of sperm cells on their way to the ejaculatory ducts. It has to be present in the appropriate concentrations, though. If the level of anandamide is too high, it can instead have a dramatic inhibitory effect on the sperm cells’ ability to fertilize oocytes.

Why is anandamide beneficial, while THC may not be?

Although THC and anandamide are both agonists of the CB1-receptors, they greatly differ in structure and therefore have different effects on certain metabolic processes. Anandamide has a much shorter half-life than THC (just a few minutes for anandamide compared to as long as 24 hours for THC). So while anandamide will degrade shortly after it contacts a receptor, THC can remain in nearby adipose tissue for much longer periods, and can continue to stimulate the receptors, ultimately causing overstimulation and potential negative effects.

As is so often the case with cannabinoid science, dosage is everything—and it may prove to be the case that very small doses of THC could benefit males who have reproductive issues that can be tied to low levels of anandamide.

Cannabis use and female fertility

While the effect of cannabis use on male fertility appears to be quite straightforward—with male chronic cannabis users being likely to experience some degree of impairment to reproductive physiology—the effect on the human female reproductive system is less clear-cut.

Female reproductive health is vastly complex in itself, as it not only comprises the ability to become pregnant but also the ability to carry healthy offspring to term and successfully give birth.

Past research has indicated that cannabis use may disrupt the menstrual cycle, suppress oogenesis (production of eggs in the ovaries) and impair embryo implantation and development. Chronic use of cannabis has also been repeatedly associated with lower birth weight (as much as a 50% increased risk), decreased birth weight and early (spontaneous) termination of pregnancy.

However, most of these findings are far from conclusive. Either the study included very few participants or confounding factors such as tobacco use aren’t taken into consideration. In fact, more recent research, like this review on infants who were exposed to marijuana in-utero, concludes there aren’t any adverse risks.

For example, a 1985 paper on foetal abnormality (Qazi et al.) after prenatal exposure to cannabis discussed five infants whose mothers acknowledged use of cannabis prior to and during pregnancy and who were born with various symptoms of growth retardation, neurological dysfunction and deformity. While it may provide helpful insight, such a small sample size is far from being enough to draw concrete conclusions, and correlation does not imply causation.

Other studies seen as providing evidence that cannabis use can cause foetal abnormalities are animal studies (Geber & Schramm 1969, Phillipset al, 1971) in which rabbits, hamsters, rats and mice were injected with vast doses of crude cannabis extract (as much as 666mg/kg in one instance!). Such massive doses of cannabis would be practically impossible for a human to consume through conventional means, and are essentially useless as a point of comparison.

In fact, many early studies that indicated a correlation between use of cannabis (or other controlled substances such as cocaine) have been later contradicted by findings suggesting that socioeconomic status and level of poverty are far more causative of low birth weight and poor developmental outcome than use of the substances themselves. This doesn’t imply that use of cannabis or other substances during pregnancy has no adverse effect, but does give weight to the idea that the risks have been overestimated and overemphasized due to politics and anti-drug bias.
