If you have a regular sex life, without contraception for 1 year and you are not pregnant, we call it infertility. The causes are not only seen in women, but according to statistics, 30% to 40% of cases are due to women, 30% to 40% are due to men, and 5% to 10% are due to both men and women, so the search for the causes and treatment must be attended by both men and women.
