Between 15 and 17% of the Spanish population, both men and women, suffer from infertility, but when is it really a real problem? One can begin to suspect that there is some difficulty when, after having had contraceptive-free sex for a year, a pregnancy has not been achieved. What can it be due to? Today we want to talk to you about biological causes that cause infertility in men and women.
Age, especially in women, is of the utmost importance, since as the years go by, women are less likely to achieve a successful pregnancy. Once you are 35 years old, the probability of having fertility problems increases dramatically. And it is that, a 37-year-old woman has a 25% probability of having fertility problems, a 41-year-old has twice that with 50% and a 43-year-old reaches up to 75%. What more biological causes can be given?
- Alterations of the menstrual cycle
When the fertility problem comes from a hormonal origin that, on occasions, can be genetic and caused by anovulation, responsible for 25% of cases of infertility, and it is essentially the absence of ovulation in a woman that normally manifests along with amenorrhea (absence of rules).
It can also be due to hyperprolactinemia, which refers to the excessive production of the hormone prolactin that stops the activity of the hypothalamus, affecting ovulation. In addition, we must speak here of the polycystic ovary syndrome, which is the hormonal disorder that occurs when the ovaries release few eggs and produce low amounts of estrogen, so that the ovaries become congested with small cysts.
And finally, early ovarian failure, which is also dominated by early menopause and occurs when the ovaries stop working before the age indicated for menopause.
- Problems in the fallopian tubes
They occur when abnormalities, damage or obstruction in the tubes occur, usually caused by pelvic inflammatory diseases such as endometriosis or sexually transmitted diseases. These are the main cause of 15% of infertility in women.
- Changes in cervical mucus
They can also cause infertility because, if the mucus in the cervix stops producing or is of poor quality, the sperm have more difficulties to reach the egg.
- Serious diseases
Likewise, taking certain medications regularly and suffering from serious illnesses, such as cancer and its treatments, can cause the reproductive system to malfunction, as it can directly affect or damage the pelvic organs.
- Transformations in the thyroid gland
Whether you produce too much thyroid hormone (hyperthyroidism) or too little (hypothyroidism) are also associated with female infertility.
Although for many years, unfortunately, women have always been regarded as responsible for a couple not being able to have children, studies have shown that, on some occasions, the problem of the problem has the problem.
- Ejaculatory dysfunction
Popularly known as 'impotence', it is a problem that affects 1 in 5 Spaniards and that usually occurs after 40 years. When this happens, the man is unable to reach an orgasm with his partner, therefore, it is impossible to procreate, since the sperm are not released in the woman's body.
Another disease that can cause fertility problems is varicocele. It occurs when the veins in the skin that support the testicles enlarge, causing poor sperm quality, affecting the shape and mobility of them.
- Gonorrhea or chlamylia
You also have to pay attention to different infections and sexually transmitted diseases such as gonorrhea or chlamydia. In addition, as we have already mentioned in the case of women, certain medications and serious or immunological diseases and their corresponding treatments can also cause sterility
Several of the biological causes that have been discussed have effective treatments, so infertility can be temporary. But other non-biological and highly toxic factors, all of them avoidable, that influence fertility such as tobacco, alcohol, exposure to toxins in the workplace (hydrocarbons, chlorinated organic pesticides and insecticides, inorganic fertilizers or metals such as lead) and even stress.
If you have any questions about infertility, we always advise consulting with a specialist, since the sooner the problem is tackled, the more likely you are to conceive!
