HOW IS IT DEFINED INFERTILITY?

The World Health Organization defines infertility as “a disease of the reproductive system, manifested in inability to achieve a pregnancy after 12 months or more of sexual relations regular and no use of contraception”.

Infertility is considered primary when there was a pregnancy prior and secondary in other situations, even if the pregnancy results in a miscarriage or ectopic pregnancy (when the egg fertilized implants itself outside the uterus).

WHAT ARE THE CAUSES BEHIND INFERTILITY?

The reality is that the more later on if you want to get pregnant, the more difficult it is. And the lifestyle of today encourages this same delay. But why, why should this happen?

From 28 years, there is a progressive loss of responsiveness of primordial follicles to the hormone levels. In this way, the ovary tends to leave to form follicles mature, giving rise with increasing frequency, the follicles containing oocytes immature or follicles with oocytes abnormal (morphology and genetic structure), and may not even be ovulating. The menstrual cycles remain generally rhythmic, regardless of the cycle ovarian.

These anomalies are due to the fact that the oocytes are stopped for several years, which allows the aging. As a result, for example, the rate of trisomy 21 increases to 1/500 newborns to 34 years of age, and 1/100 newborn to 39 years.
