The Effects of Marijuana on Fertility in Women and Men

Fertility in women and men can be a fragile thing and it often surprises hopeful parents to find out that activities they considered harmless are actually lowering their chances to conceive.

One of these activities is that of smoking marijuana. While it’s entirely possible for those who smoke marijuana to conceive, studies have shown that the herb does have a significant effect on fertility.

Findings

Smoking marijuana has been found to make sperm less fertile and this effect is true whether it is the male or female doing the smoking. The presence of marijuana effectively makes the sperm “high” and causes them to be hyper. This hyperactivity leads to the sperm being too fast too soon and therefore missing their opportunity to meet the egg and fertilize before they burn out.

Men

While plenty of men who smoke marijuana have fathered children, it is typically those that are more fertile than others naturally, as marijuana-smoking men were found to have lower volumes of semen overall.

This means they’re delivering about half the amount of sperm to their partners and drastically lowering their chances of conception due to the poor morphology and mobility of the affected sperm. Morphology, or the shape of sperm, makes it challenging to conceive, and marijuana regularly changes the size and shape of sperm.

Studies have also shown that marijuana has a negative impact on a man’s sex drive. This is due to the fact that the herb will initially increase testosterone and other sex hormones, and then cause them to drop suddenly and dramatically below normal levels. This drop leads to a lower sperm count by an average of 29% compared to that of non-smokers.

To get a better picture of the problem, a recent study took sperm samples from 318 men who regularly smoke marijuana, and only 4% of the samples were normal and healthy sperm.

Women

The effect of marijuana isn’t only found in the fertility of men. When women smoke marijuana, the active ingredient called THC can be found in her reproductive organs and fluids. When sperm comes in contact with the THC in the female’s body, it has the same effect as when the male is the smoker: the sperm becomes hyperactive and burns out too quickly.

In other words, the sperm get high when they come into contact with a female’s cervix when the female has recently smoked marijuana. In effect, her habit changes his sperm and lowers their chance of conceiving.

Conclusion

Due to these findings, it’s highly recommended that partners trying to conceive avoid marijuana in both the male and female. Should you get pregnant despite the lower chances of conception, you should immediately stop smoking marijuana, as it’s been found to lead to a higher risk for premature birth and dangerously low birth weights.

The good news for couples trying to conceive is that a male’s sperm regenerates in 74-day cycles, so fresh and healthy sperm is just a few weeks away if changes are made today.
