Marijuana Delays Ovulation

Regular Cannabis smokers are at a higher risk of not ovulating. The 2016 report says that marijuana disrupts the menstruation cycle leading to cycles without ovulation (anovulatory cycles). Scientists are not very sure how THC affects the sexual function of women trying to get pregnant. THC affects the HPG, which is a hypothalamic-pituitary-gonadal that controls how the sex hormones. Being exposed to this THC can lead to the secretion of luteinizing hormone, which influences the chances of conceiving. Subsequently, marijuana affects the luteinizing hormone in women.

High amounts of THC decrease the production of estrogen. Without a higher estrogen spike, ovulation won’t occur. And if the ovulation does not happen, the egg won’t be released, thus leading to fertilization failure. However, several older studies have shown that THC can block ovulation in mammals, such as primates. THC appears to have this effect by preventing the production of an important hormone for ovulation called luteinizing hormone.

Marijuana Lowers sperm count

Smoking Cannabis can seriously harm a man’s reproductive system. Research shows that the use of marijuana also affects fertility in men, and this is because marijuana can impair sperm count and the ability to reproduce. However, a recent study from Harvard refutes these findings and claims that there is no evidence of the harmful effects on fertility.

Previous studies have shown that daily and intensive use of marijuana leads to a decrease in the total number of sperms by up to 30%. Men who smoke marijuana more than once a week have lower sperm count than nonsmokers. Long-term cannabis users experience a decrease in seminal vesicle and ejaculate volume. In addition, the drug affects erectile function and libido.

These observations emphasize that the endocannabinoid system plays an essential role in maintaining reproductive function in men. Therefore, changes in its function can lead to impaired spermatogenesis. However, the effect of smoking marijuana on the quality of sperm nuclei is still unclear. Since there is no conclusive determination on this subject, try discouraging your male partner who smokes marijuana while trying to get pregnant.

It Can lead to Deterioration of the Existing Fertility Issues

There is no conclusive evidence that the use of marijuana causes infertility. However, studies have shown that it can decrease sperm count and delay ovulation. Besides, it can also disrupt the hormones that encourage pregnancy. Normally marijuana interferes with the functioning of the endocannabinoid system, which is involved in the ovulation, timing, and proper implantation of the embryo. Subsequently, marijuana can worsen any fertility issue by affecting the reproductive system.

Women who use cannabis have an increased likelihood of infertility. Furthermore, they may also have a higher risk of miscarriage. When a woman uses marijuana, it can cross the placenta affecting the fetus, even though studies are not readily available on the exact impact on the baby. It is advisable to avoid using marijuana while pregnant or trying to get pregnant to avoid any negative side effects.

Marijuana Suppresses Vital Hormones During the Premenstrual Phase

At the premenstrual period (luteal phase), hormonal fluctuations cause many symptoms, such as pain, mood swings, bloating, and fatigue. At this time, the progesterone hormone levels rise significantly while the levels of other hormones like estrogen decrease.

It was discovered that progesterone could treat severe premenstrual syndrome. However, recent studies have shown this to be ineffective. In fact, while it’s generally believed that the abnormal premenstrual signs are associated with lower progesterone levels when they are supposed to be high. Some premenstrual syndromes are accompanied by an excessive increase in progesterone and a decrease in estrogen levels.

Premenstrual symptoms that are serious enough to qualify for PMS are the reason why there might be hormonal fluctuations. In addition, studies show that marijuana use lowers progesterone levels at the luteal phase and alters the levels of other hormones such as cortisol and prolactin. Furthermore, the THC effect on the luteinizing hormone, which starts during ovulation, is observed at the luteal phase. The luteal phase is the period between ovulation and the onset of menstruation.

Although the exact mechanisms of action are still not fully described, the endocannabinoid system still plays a pivotal role. Women who have abnormally severe symptoms during this period may benefit from the targeted cannabinoid therapy. Indeed, countless women around the world experience subjective relief from marijuana at the premenstrual phase. However, this may be due to the anxiety-reducing and relaxing properties of cannabis rather than a direct effect on hormone levels.
