Sperm in the first fraction of ejaculate are more numerous, move more and present better quality DNA than those lagging behind.

The researchers’ hypothesis was that, comparing the different fractions of semen in an ejaculation, the first would contain sperm with better seminal parameters and could be used as an effective method for selecting sperm prior to fertilisation. “Ejaculate has always been considered as a whole. However, we believe that it is divided into two quite different phases due to its composition and physiological functions, aimed at achieving two equally important actions in terms of reproduction,” María Hebles, co-director of the reproduction laboratory at the Ginemed Clinic in Seville and lead author of the study, explains to SINC. The first objective of ejaculate would be to fertilise the egg and the second so that no other male has the opportunity to fertilise it. Therefore, the first fraction is characterised as having protective components such as zinc, whereas the second contains elements that can cause damage to sperm. The first fraction of ejaculate is characterised as having protective components such as zinc, whereas the second contains elements that can cause damage to sperm However, for their use in assisted reproduction techniques, the liquid is normally collected in a single container, and therefore both phases are mixed together. This could have a detrimental effect on the sperm population,” adds Hebles. Based on this, the specialists asked 40 participants to collect the ejaculate separately into two containers, one for each phase. They then separated the first and the second phase and studied the characteristics of the sperm in each of them. Data suggests that the first phase contains an enhanced subpopulation of sperm, with less sperm DNA fragmentation. Therefore, the use of sperm from this fraction can have a positive effect on fertilisation and embryonic development. “As we were expecting, the sperm from the first fraction of ejaculate were faster moving and the count was higher, and more importantly, they had higher DNA integrity than sperm from the second phase,” says the researcher. In light of the results, the experts now have a protocol requesting all patients to collect the ejaculate in two fractions, “improving the quality of the sperm used for fertilisation simply and at no cost at all,” Hebles adds.

Read More »The ratio of male to female births, called the sex ratio, is about 105 to 100, according to the World Health Organization (WHO). This means about 51% of deliveries result in a baby boy.
Is it a boy or a girl? That’s the most common question I hear during ultrasounds. Many couples want to know before the 20-week ultrasound. And there are plenty of old wives' tales that patients reference when guessing the sex of their baby. My general response is that it's a 50/50 chance that a woman will have a boy or a girl. But that's not exactly true – there’s actually a slight bias toward male births. The ratio of male to female births, called the sex ratio, is about 105 to 100, according to the World Health Organization (WHO). This means about 51% of deliveries result in a baby boy. While the sex ratio can be distorted by populations that selectively value male over female births, there could be another explanation. Research suggests the slight natural skew of the sex ratio could be nature’s way of adjusting for higher death rates in males due to injuries, accidents, and war. For example, in England around 1900, 50.8% of births were boys. Following World Wars I and II, the rate of male births increased to 51.6%. This may not seem like a big difference, but it resulted in 32 more boys than girls born for every thousand births. Similar changes were seen in other European countries as well following these wars. It seems like sex ratio shifts should be a random phenomenon. But from a medical standpoint, perhaps there’s a genetic explanation to changes in the numbers of boy and girl babies at different times in history.
