Study on fertility and age of man

One study notes that there is not enough evidence to show the relationship between male fertility and male age.

In a prospective study conducted in Israel on male fertility and male age, Dr. Dain has focused on different studies published in a magazine with a high impact index on the subject that has included between 200 and 2000 men and that has determined that there is no possible conclusion, at least for the moment.

Male fertility at the time of having children

This study, carried out by a group of scientists from Israel, has been planned before carrying it out, unlike the retrospective studies where a study hypothesis is selected according to the data that can be extracted from the history, it has tried to relate the age male with the same fertility.

Dr. Lena Dain, from a medical center in Haifa, has been the one who has directed the project organizing a review of 10 works focused on this field. It is true that female fertility is reduced from the age of 35 in an important way, plummeting after 40 years and, moreover, with the incorporation of women into the world of work, more and more couples see relegated his fatherhood in order to find the ideal time for it.

Dain notes that, although the fertility of men also decreases after 40 years, it is not as specific as that of women, although pregnancy rates, according to the review made of patients over 40 years, it drops to 13%, almost in the same way as the birth rate. However, there are not enough data to prove that the age of the male really affects fertility because many factors influence, starting with those of the couple as such.

In the United States they do seem to have found a small connection because of the percentages of pregnancy found in the three established groups of men up to 35 years old, between 36 and 40 years old and those over 40, but without enough arguments to focus this result only in the male.
