The various causes of infertility

    In women, it may be due to ovulatory problems, such as anovulation (no ovulation) or dysovulation (abnormal ovulation). It may be related to endocrine causes (thyroid problems or adrenal gland), or to treatments such as chemotherapy or radiation that affected the ovaries. It can also come from mechanical causes: blocked tubes (due to genital infection poorly treated, for example), endometriosis (which affects the fallopian tubes, uterus and ovaries), problem with the cervical mucus, or finally come to immune causes fertilization but is not successful because the body of the woman rejects the embryo.

    In men, it is important not to equate sterility to impotence. Infertility can be due to an abnormality in sperm as azoospermia (absence of sperm in the semen). It can also be caused by an abnormality of the position of the testes, varicocele to (veins are too dilated, causing a backflow of blood and too hot testes). Infertility can be due to finally oligospermia (reduced secretion of sperm), or sperm that move badly, whose morphology is abnormal or that are fragmented.

 

A growing phenomenon

Thus, it appears that 26% of women who gave birth became pregnant within the first month, or about a quarter, but 32% of pregnancies occurred more than 6 months. Among them, 18% waited one year and 8% waited two years. The figures of the Observatory are a bit more pessimistic but probably closer to reality as possible to include non-maternity recruited couples who never have a child and abandon their parental project. Thus, 46% of couples do not get pregnant 6 months after stopping contraception, 24% after one year and 11% after two years.
