The other day I saw on the website of women's magazine "Lady Pravda" one article on issues of relations between men and women. Actually, i would have passed it by, but I was intrigued by one part there, and I quote it now:

"The female reproductive system is drastically different from the men’s one. Our eventual choices produce up to 12 million spermatozoa per hour, and if you count how much semen is formed in male germ gland during their lifetime, you will get the cosmic digit - a few trillions! If every man's semen could evolve into the embryo, there would be no place to live on our tiny planet. It's frightening to imagine the number of women that our hypothetically faithful beloved could fertilize. Completely different story is with the female physiology – there are just 400 eggs for the whole life. So our gametes are the greatest value of nature."

Three weeks ago, in Israel was born the first child conceived through the sperm of a man who had died of cancer six years ago, leaving no instructions regarding the right to dispose of his genetic material, which he had put in a special bank before the course of chemotherapy.

The newborn’s mother had never seen the father of her child. The woman who had been long dreaming of getting pregnant, but did not wish to turn to sperm banks was found by grieving parents who had lost their only son because of cancer.

The parents of the deceased considered themselves entitled to use the sperm of their son to conceive grandchildren and began to look for a candidate for the role of the mother of the child.

It is a miracle

Recently I commented on the news about Israel where had been born the first child conceived from sperm of a young man who had died of cancer six years ago. The parents of the deceased and the woman who had agreed to carry a child to term, quickly managed to reach an agreement, but the difficulty was that the deceased had not left any directions about the disposition right of his genetic material after death. The well-known lawyer in the country, leader of the "New family", Irit Rosenblum, who had been dealing with the issues of so-called "biological testament” for many years, came to the aid of the family. The court took the side of the claimants and gave permission for the procedure.

Despite the fact that the practice of biological wills exists only in Israel, the experience shows that more and more people around the world are interested in the issues of posthumous donorship.

The success of oocyte cryopreservation depends on the age of the patient?

Working together, experts from New York Medical College and the University of California became the first to identify the relationship between the successful outcome of IVF with frozen eggs and the age at which the patient has resorted to cryopreservation.

An idea that young women who, for one reason or another want to postpone having children, need to freeze their eggs, so that by the time they are ready for kids, they are able to use their own "young" biological material, is now gaining increasing popularity. However, until now experts could not predict the chances that the egg is successfully thawed and maintains its viability.
