The male factor is one of the aspects that is having the most relevance in assisted reproduction recently. Different diagnostic techniques of a genetic nature have been used to be able to analyze the role that the man is playing in achieving a pregnancy.
The period of abstinence is an aspect that has varied over the years, initially thinking that the greater the abstinence, the better the result of both the seminal diagnosis and the embryonic evolution and term pregnancy. Some studies show that a period of frequent ejaculation after a period of abstinence can improve sperm quality.
The period of abstinence differs according to the assisted reproduction unit attended and the standardization of the processes. The recommendations of the World Health Organization is to have sexual abstinence of between 2-7 days. In the event that abstinence is less than two days, we will find spermatozoa that possibly present less DNA fragmentation, but the count of the number of spermatozoa is lower than in normal conditions. If we have a high abstinence period, we are likely to find ourselves with reduced sperm motility.
In conclusion, it is important to have an optimal abstinence period according to the recommendations of the assisted reproduction centre in order to maximize the chances of success in each case.
