The fight against infertility will not come to a halt


It is not the first time that on this blog we have addressed the problem of infertility in men and women. In this case, once again, we probe deeper into the subject with the intention of focusing on the latest developments in the field.

At Best Doctors we are convinced that we must never lose sight of the importance of new treatments and alternatives for those who want to have children, and now can not for a variety of reasons.

There are more and more options available

We must be aware of the extraordinary progress made in the last number of years. Without going into further detail, the average age of women in Western societies who become pregnant is much higher today than a few decades ago.

Thanks to the assisted reproduction technique, it has achieved something that seemed impossible – a field that is constantly evolving and creating new opportunities for those couples who had even given up the prospect of having a baby.

New clues on the interaction between egg and sperm

The finding revealed by a team of scientists at the Wellcome Trust Sanger Institute in the UK, which was published a few months ago by the journal Nature, has brought to light the process by which the Juno (whose discovery is in itself a finding) egg receptor identifies the Izumo protein on the surface of the sperm, and “paves the way” for human reproduction.

According to the words of Gavin Wright, an investigator at the Wellcome Trust Sanger Institute involved in the research, there is no doubt about the scale of the discovery: “We have revealed one of the mysteries that has remained hidden for the longest time in the field of biology by identifying those molecules of the egg and sperm that necessarily must team up at that moment in which we are conceived.”

So far, the functioning and implications of Juno and Izumo molecules has only been able to be demonstrated in laboratory mice; although, what is real is the existence of both molecules in the gametes (sex cells) in humans.

Therefore, it should now be noted whether the finding is also applicable to the reproduction of people. If that were the case, it is likely that a solution could be found to solve a part of that 15% of reproductive treatments which, for no apparent reason, can not achieve success at present.

It is obviously a very interesting job, both from a scientific perspective as well as from a point of view of its possible future applications to the treatment of infertility in patients.

As is customary in this blog, we will continue echoing this news in its earliest stages, but always with due caution. To the extent that we are aware of the complexity of the processes and time frames required from when scientific research begins until its actual implementation in the medical field.
