First Part of Semen Is More Efficient for Fertilization • Mirror Daily

Sperm fertilizing ovule egg.

Medical researchers claim there is a two-step process involved during male’s ejaculations. Uncovering these steps could help against infertility as the first part of semen is more efficient for fertilization, doctors have stated in a recent study.

Young couples and families struggling to conceive might be relieved by the recent medical findings that experts have made. Recent semen analyses performed by the reproductive laboratory in the Ginemed Clinic in Seville have proven that ejaculation occurs during a two-step process, which is usually preceded by a pre-ejaculatory moment.

This aspect was not known until recently and scientists believe it could help prevent infertility. According to them, the first part of semen is more efficient for fertilization due to its enhanced properties. The first fraction of ejaculate contains larger amounts of sperm and a highly qualitative DNA. Given these characteristics, the first part of semen that is normally ejaculated during an intercourse has many more chances of fertilizing the ovule and, thus, leading to a pregnancy.

Doctors think the findings of the new study may not be applied by regular patients as it is very difficult, if not downright impossible to control the two phases of the ejaculation process. However, they believe reproductive laboratories will most certainly take into account the recent information when performing in-vitro fertilization.

In doctors’ opinion, in-vitro fertilization could suffer significant changes in the future due to the recent find. Doctors will most likely distinguish between the first part and the last part of semen. The first ejaculate fraction is expected to be frequently used in in-vitro fertilization as it can increase pregnancy chances.

Moreover, the recent tests have shown that the DNA contained in the first part of semen has a very good quality compared to the samples withdrawn from other semen parts. This means the use of good quality DNA in in-vitro fertilization can prevent the occurrence of genetic disorders in embryonic development. Weak DNA quality is considered the main responsible for many children diseases and it has been linked to many genetic disorders.

The ejaculation moment is preceded by a pre-ejaculatory phase, which also presupposes the release of a substance that was labeled for a long time as semen. Yet, Maria Hebles, the leader of the scientific team in the reproductive laboratory claims the substance that is released during this stage is not semen but rather a fluid coming from the urethra.

The study that was carried through by the reproductive laboratory in Ginemed Clinic in Seville involved the careful analysis of many sperm samples. Their composition was subject to a thorough microscope investigation allowing doctors to determine the levels of sperm contained therein.
