Cannabis has been associated with a variety of reproductive effects including low libido, testicular atrophy, sexual dysfunction, and alterations in semen parameters such as sperm count, concentration, morphology, and motility.
There is also concern that THC may cross the placenta and affect fetal development and/or cause adverse birth outcomes. As a result, it is important to avoid marijuana use during pregnancy and lactation.
Reduced Sperm Motility
The most common way that cannabis negatively impacts the male reproductive system is by interfering with sperm health. This is due to a variety of factors, including a reduction in sperm count and concentration, reduced sperm motility, and increased abnormal sperm morphology.
Sperm motility refers to the ability of sperm cells to move efficiently and effectively through the female reproductive tract or through water to reach an egg. This is an important function, as it increases the chance of sperm fertilizing the egg.
This can be determined in a semen analysis, which is typically performed on one ejaculate sample. To get an accurate reading of sperm motility, the ejaculate sample must be collected as soon as possible after the onset of ejaculation (preferably within the hour).
In addition to testing for sperm count and concentration, the semen analysis also tests for sperm motility. If a man has low sperm motility, he can try to make changes in his lifestyle that may improve this issue.
Many men with poor sperm motility have underlying medical conditions or genetic conditions that affect their sperm health. These problems are usually addressed through treatment. If a man has a condition that reduces sperm quality, he may have to undergo surgery to repair the problem.
It is also important to note that there are some lifestyle changes that can help improve sperm quality and motility, such as exercising more regularly, eating a nutritious diet, avoiding alcohol, and quitting smoking. However, these changes alone aren’t going to fix a problem with sperm motility, so it is a good idea to talk with a healthcare professional about what steps you can take to improve your sperm’s health and increase your chances of getting pregnant.
The most effective way to get your sperm’s health in tip-top shape is to avoid smoking and other factors that can reduce your fertility. This is not only good for your mental health, but it can also increase the chances of you and your partner conceiving a baby.
Lower Testosterone Levels
Testosterone is the primary hormone responsible for producing male sex characteristics, including libido and muscle mass. It also plays a role in regulating the production of sperm and red blood cells. When it levels fall, men become less interested in sex and struggle to get an erection.
Low testosterone can be extremely dangerous and affect many areas of a man’s body. In addition to causing a lack of libido, it can cause weight gain and other health issues. It also increases the risk of developing gynecomastia, which causes enlarged breasts.
Studies have shown that marijuana can reduce testosterone in both animal and human populations. This effect is attributed to the cannabinoids found in marijuana that act on endocannabinoid receptors in the pituitary gland, testes, and sperm cells.
Researchers have also found that weed can decrease the size of testes and interfere with sperm morphology. This can lead to a condition called “testicular atrophy,” which affects the testes’ ability to produce sperm.
Despite these concerns, the effects of cannabis on testosterone remain under investigation. Some studies have shown that THC can increase testosterone levels, while others show that it doesn’t have an impact on the hormone at all.
One study compared the testosterone levels of 20 men who smoked marijuana on a daily basis for six months with a control group of men who had never smoked cannabis. The testosterone levels of marijuana users were significantly lower than those of non-users.
This was true even though the quantity of marijuana smoked by each participant was similar. The study’s authors said that these results demonstrate that the level of THC a person smokes is what matters most when it comes to lower testosterone levels.
In a second study, researchers examined the relationship between marijuana use and serum testosterone in males. This study was the largest to date on the effects of marijuana on testosterone and is the first study to examine these effects by age group. In fact, the authors concluded that the relationship between marijuana use and testosterone in men is not influenced by time since last use, frequency during regular use, number of joints or pipes smoked per day during regular use, or years of regular use.
Decreased Ovulation Rates
The effects of cannabis on the reproductive system are still under study, but the evidence is mounting that marijuana use may impact fertility. Although the research is still in its early stages, the Society of Obstetricians and Gynaecologists of Canada recommends that women not smoke cannabis while trying to conceive or while breastfeeding or lactating.
Many factors play a role in determining ovulation, including the length of a woman’s menstrual cycle, diet, and hormone levels. Marijuana has been associated with decreased ovulation rates in women, as well as an increased risk of anovulatory cycles (no ovulation occurring).
In addition, marijuana can negatively affect the luteinizing hormone (LH), which is responsible for stimulating ovulation in women. Similarly, it can reduce the production of testosterone in men, which is necessary for healthy sperm production.
While the link between marijuana and fertility has been studied for years, most studies have had small sample sizes. The most recent studies have been performed with larger populations and more accurate testing methods, but there is still much to be learned about the impacts of marijuana on the reproductive system.
Another reason why cannabis could negatively impact fertility is because it can cause testicular atrophy, which is a condition where the testes diminish in size and function. It is a condition that can be reversed, but it may have lasting effects on fertility.
It also can interfere with sperm’s ability to undergo the “acrosome reaction,” which is a series of changes that occurs in the cap of a sperm following ejaculation. This process is important for sperm to penetrate an egg.
Despite these negative effects on the reproductive system, many women do not consider that cannabis use is harmful. However, if you want to increase your chances of conceiving, it is best to quit using the drug altogether.
In fact, the American Congress of Obstetricians and Gynecologists (ACOG) advises that all women, regardless of their ovulation cycle, should avoid cannabis. There are some medical reasons why women may choose to smoke marijuana, but it is not worth the risks to their health.
Cannabis (marijuana) has a negative impact on the male reproductive system, especially in terms of sperm count and concentration. It also affects morphology and motility, and is associated with an increased risk of testicular cancer. In addition, cannabis use has been linked to a number of urological dysfunctions such as erectile dysfunction and infertility .
Cannabis effects on the male reproductive system are largely attributed to its effects on the endocannabinoid system (ECS). The main components of the ECS include tetrahydrocannabinol (THC) and cannabidiol (CBD). Both substances are found in large amounts in marijuana.
THC interacts with the CB1 and CB2 receptors in the brain, causing feelings of euphoria. CBD inhibits the breakdown of endocannabinoids and prolongs their action.
The endocannabinoid system has been shown to influence many aspects of the male reproductive system, including the production of sperm, ovulation and luteinizing hormone levels. In particular, cannabis use is associated with reduced testosterone and luteinizing hormone levels and decreased follicle-stimulating hormone (FSH) levels in men attempting to conceive.
Some studies have suggested that AEA, one of the compounds in cannabis, is responsible for these effects on the endocannabinoid pathway. However, there is little evidence to support this.
While some of the effects of marijuana on the endocannabinoid pathways are thought to have negative impacts on fertility, there are other potential benefits from its use. For example, cannabis use can help reduce anxiety and depression in some individuals.
Additionally, cannabis can increase libido and enhance sexual performance in some individuals. This can be particularly useful in patients who have experienced a significant loss of libido from other medical conditions or are experiencing difficulty conceiving due to an unfavorable lifestyle.
A study published in the journal Fertility & Sterility examined the effects of chronic exposure to a moderate dose of Delta-9-tetrahydrocannabinol on the semen of healthy nonhuman primates. The sperm of these primates were exposed to the drug once daily for seven months at a dose that is equivalent to a heavy medical marijuana dose in humans.
Results showed that the THC-treated animals had a significant decrease in sperm count and concentration, a higher rate of scrotal hyperplasia and a higher percentage of abnormal sperm. These findings are particularly concerning given that these are likely to occur at lower dosages than those used by most recreational or medicinal marijuana users.
