It is best to have a clear understanding of the dangers of smoking on sperm, as the harm is much greater than imagined! There is a close negative correlation between toxic chemicals and reproduction. Whether it's smoking, drinking alcohol, or other recreational drugs, they all have side effects on the reproductive system, especially for men. Its impact on sperm morphology and sperm health reduces male fertility and the effectiveness of in vitro fertilization treatment.

The effect of smoking on sperm quality

1. Abnormal sperm morphology

Through research on male sperm samples, it has been shown that many smokers have distorted sperm shapes and smaller volumes, and this morphological difference is evident among males who have smoked within the past three months.

The reason for the change in sperm shape is the DNA arrangement of sperm cells. When the arrangement is not tight, the shape and size of sperm will be affected.

2. Decreased sperm count.

A recent study has shown that compared to non-smoking men, men who smoke once a week have significantly fewer sperm and semen, which greatly affects fertility rates, as most smoking addicted men are either unable to conceive offspring or are highly susceptible to deformities, low birth weight, or stillbirth.

It is best to have a clear understanding of the dangers of smoking sperm, as they are much greater than imagined.

3. Decreased sperm motility.

There is a component called THC in tobacco that affects the ability of sperm to fertilize eggs, thereby reducing egg tolerance and fertility. Especially when a woman smokes, THC will appear in her vagina, fallopian tubes, uterus, and cervical tubes after smoking, as well as be released in her vaginal secretions and reproductive fluids. Therefore, even if men do not smoke, their sperm may react with THC, leading to changes in sperm motility.

4. The number of sperm reaching the egg decreases.

When a man smokes toxic substances, his sperm will be overactivated, and the number of sperm swimming from the vagina to the cervix and then to the uterus will decrease. The process of excessive activity also occurs in non-smoking males, which helps sperm pass through the eggshell. But under the influence of cigarettes, this excitement will not last long, and such sperm will be exhausted midway and unable to reach the egg and fertilize it.

5. Decreased testosterone levels.

Smoking can lower levels of testosterone in the body. Testosterone is a hormone responsible for producing sperm and supporting erections. The smoking data that leads to a decrease in testosterone is still being studied due to different people's reactions to cigarettes.

However, there is no doubt that a decrease in testosterone levels can lead to a decrease in sperm count and concentration, as well as a decrease in erectile and maintenance abilities, leading to issues such as erectile dysfunction.

It is best to have a clear understanding of the dangers of smoking on sperm, as the harm is much greater than imagined! If you are planning to undergo in vitro fertilization treatment and are affected by smoking, it is recommended to quit smoking immediately. It is important to understand that any psychotropic substance is harmful to the human body. In the long run, the short-term happiness brought by long-term smoking is far less than the harm.
