The male factor has become one of the most relevant aspects of assisted reproduction recently. Different genetic diagnostic techniques have been used to analyze the role that the male plays in achieving a pregnancy.
The period of abstinence is an aspect that has varied over the years, thinking at first 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 ejaculations 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. If the abstinence is less than two days, we will find spermatozoa that possibly have less DNA fragmentation, but the count of the number of spermatozoa is lower than in normal conditions. If we have a high abstinence period, it is likely that we will find reduced sperm motility.
In conclusion, it is important to have an optimal period of abstinence according to the recommendations of the assisted reproduction center in order to maximize the chances of success in each case.
