The origin and causes of infertility can be very varied. In general, it is established that in 40% of cases, the origin of infertility is in the male. In another 40% the origin will be in the female, and in the remaining 20% of cases a mixed causal factor appears. The most frequent male cause is the decrease in seminal quality, even the absence of sperm in ejaculation, although it is not the only one (Genetic Diseases, age, etc.). At the female level, the most common cause of infertility is the woman’s age. The role of women in developed societies has changed greatly in recent years, leading to a delay in the age at which women seek gestation. From the age of 35, there is a decline in female fertility rates, which becomes more pronounced after the age of 38.
