Seminal alterations due to oxidative stress could be repaired by oocytes of young women as the egg donors

The presence of high levels of oxidative stress in semen does not have an influence on the possibility of getting pregnant with egg donation

Seminal alterations due to oxidative stress could be repaired by oocytes of young women as the egg donors


The presence of oxidative stress in men’s semen is one of the alterations that can damage sperm and hinder egg fertilisation, worsening the quality of the embryos and reducing the chances of pregnancy. In young women as egg donors, the oocyte could correct this damage.

This was the result of the study “Oxidative stress in sperm does not affect sperm parameters and reproductive outcomes in ICSI cycles”, presented at one of the keynote lectures in the official programme of the annual meeting of the European Society of Human Reproduction and Embryology (ESHRE), and held in Lisbon from 14 to 17 June.

The research findings indicate that “the presence of oxidative stress in semen is not related to a better result in pregnancy rates when donor eggs are used”, as Dr. Aida Pujol, a biologist at Eugin and author of the paper, pointed out.

Egg donation: best results in Europe

Also on this Tuesday’s session, the presentation entitled “European and Global ART monitoring session” has presented indicators that place the overall pregnancy rate in Europe above 50% in treatments with donor eggs.

“It’s the first time that an overall success rate for treatment of this type of over 50% has been presented in Europe,” says Dr. Rita Vassena, scientific director at Eugin, for whom it proves that “egg donation is an increasingly safe treatment “. At Eugin Clinic, the chances of success of such treatments rise to 65%.

Admittance to the ESHRE Executive Committee

Dr. Rita Vassena

Indeed, Dr. Vassena has been appointed a member of the ESHRE Executive Committee, composed of fifteen members, which represents a genuine recognition of her career as a researcher in the sector’s most distinguished international scientific and medical society. In fact, ESHRE counts among its founders Robert Edwards, Nobel Prize laureate, the founder himself of assisted reproduction, and in addition today numbers thousands of members all over the world.

This fertility clinic also collaborates in different scientific projects with working groups from well-known universities such as the University of Milan, Leeds University, Cardiff University, Ghent University and the University of Barcelona, which gives their research a high degree of diversity, richness and internationality.

Benchmark event

Lisbon hosts this week’s annual meeting of ESHRE, where thousands of professionals present the most outstanding developments from the embryology and assisted reproduction sectors. This year, Eugin has played a very prominent role, since it will present up to eight studies of its own during the course of the event.
