Quality of semen with obesity

In recent years the number of overweight people has increased, as a result of this you can observe the negative consequences that a high body mass index presents to the body.

Below you have an index with all the points that we will discuss in this article.

Quality of semen with obesity

It is estimated that between 25% and 30% of fertility problems are attributed to alterations in the levels of seminal quality. In some cases, obesity may be the reason why there are not enough healthy sperm to fertilize the ovule and therefore there are problems to achieve pregnancy. It is proven that in women, a BMI above 30 decreases the probability of pregnancy, all points to the fact that obesity in men can affect the seminal quality, and therefore decrease the probability of pregnancy.

Hormone levels in obese men

Obesity in men

In men, obesity does not affect in the same way as in women. In cases of female obesity, the impact that overprestration has on fertility is much greater and with the loss of weight an immediate improvement is observed, in many cases it is possible to restore ovulation naturally, solving many diagnoses of ovarian syndrome polycystic

In men, the impact that obesity has on sperm is much less if observed individually, if analyzed at a population level if it can be a cause of male infertility, since it alters the normal levels of production and maturation of sperm .

Due to the studies carried out so far we have not observed a single cause that explains a semen of worse quality in obese men, it seems that the most altered factors are:

  • Less seminal volume.
  • Smaller concentration of sperm.
  • Worse maturation of them.
  • Higher sperm DNA fragmentation index.

The most likely explanation is that the body is not able to generate enough hormone for the process of spermatogenesis to occur normally, men with a BMI greater than 30 tend to have low levels of androgens, especially testosterone, that would affect the production of sperm.

Percentage of altered sperm

Spermatic alterations

In addition to a decrease in sperm concentration, the quality of the sperm formed is lower, since the sperm generated have a high rate of DNA fragmentation which makes them unstable and unable to reach the ovum and penetrate it, life mean of these sperm is much lower.

In severe cases of seminal alterations, such as azoospermia (absence of sperm in the ejaculate), hormonal levels should be checked, in case it is associated with hypogonadotropic hypogonadism, that is, in case sexual hormones are not produced or the levels of these are very high. low.

It has been observed that if obese men through diet and exercise lose weight, the seminal levels improve significantly, so if after the semen analysis the seminal improvement is confirmed they can try to look for the pregnancy in a natural way, without the need of assisted reproduction techniques . Although the reasons are unknown, if this weight loss is caused by a surgical intervention such as a reduction of stomach or the insertion of a gastric balloon, the seminal parameters do not improve.

Gonal-f is a hormonal drug used in assisted reproduction treatments to cause the development of multiple follicles in the ovary. It is composed of the follicle-stimulating hormone (FSH), a gonadotropin that acts in the menstrual cycle of women. There are several formats of Gonal-f in the market, but one of the best known is the one that is administered with a pen-type injector.

According to the latest report of the Spanish Fertility Society (SEF), in 2016 were carried out 138,553 cycles of in vitro fertilization (IVF) and 36,463 cycles of artificial insemination (AI), which resulted in a total of 37,503 babies born . This represents an increase of 8% in the use of assisted reproduction techniques with respect to the previous year, which shows that more and more couples need help to have the opportunity to become parents. After a year of sexual intercourse without achieving pregnancy, a couple is considered to have sterility problems, so it is advisable to start doing diagnostic tests and determine the most appropriate assisted reproduction treatment in each case, as we will discuss throughout this post.
