Let's start with a scientific definition. Infertility (lat. - sterilitas) is the lack of fertility in women (female infertility) and in men (male infertility).

Some more statistics. In the first year of marriage, pregnancy occurs in 80–90% of women; lack of pregnancy after 3 years of marriage indicates that the chances of its occurrence are reduced every year. Marriage is considered infertile if the pregnancy does not occur within more than two years of sexual activity without the use of contraceptives. Female infertility is observed in 60% of cases, male in 40%.

Female infertility can be absolute and relative. Infertility is considered absolute if there are deep irreversible pathological changes in the woman’s body that completely exclude the possibility of conception (absence of the uterus, fallopian tubes, ovaries).
Infertility is considered relative if the cause that caused it can be eliminated.

This separation of infertility can be considered to some extent conditional, since some of its forms, previously considered absolute, are now relative to the possibility of in-vitro fertilization.

In addition, infertility is divided into primary and secondary. If a woman who lives sexually has never had a pregnancy, they talk about primary infertility. Secondary infertility is the absence of conception after a past pregnancy. If conception occurs, but for some reason the pregnancy does not end and the marriage remains childless, they talk about one of the varieties of infertility - miscarriage.
