IVF children = normal children

I have often expressed my opinion on the numerous pseudoscientific researches on various pathologies, that IVF children are allegedly suffering – they are all trumped-up investigations, caught by different media greedy for sensations. Meanwhile, the difference between an "average" IVF child and a child conceived in a usual way, can exist, but, paradoxically, it isn’t due to the way of conception. I’ll try to explain this "phenomenon".

The differences between an average IVF child and a child conceived naturally, can really take place. It may occur due to two factors. The first one is a multiple pregnancy. As it is known, the probability of birth of twins, triplets, etc. in nature is less than 1%. At the same time, about 28% of IVF pregnancies are multiple.  Any entry-level gynecologist can describe all the «amenities» of a multiple pregnancy: higher risk of premature birth, and usually weaker babies.


Does infertility begin in the womb already?

One of the causes of infertility is the inability to produce viable gametes - sperm and eggs. Reproductive age of a person takes about from 15 to 45 years. However, the progenitor cells from which gametes develop, are formed much earlier - in the very early stages of embryonic development, when the cell's DNA carries modifications, derived from parents, that do not affect the gene sequence itself, but affect the conversion of genetic information of the gene in the "end product": RNA or protein

These changes are accumulated during the life of the parents and must be corrected during embryonic development. Most of these modifications are reprogramming, when the fetus is not older than six weeks. But the U.S. scientists have conducted a research and found another one modification - the final stage of this process, which takes place after the age of six weeks.


One more step to the victory over the unexplained infertility

Sometimes it happens that all the indicants are normal, but the couple still can’t conceive. If doctors don’t manage to find the cause, preventing natural conception, the diagnosis "unexplained infertility" will be made, also called idiopathic. According to the statistics, about 15% of couples, having problems with conception, face the infertility of this type.

Scientists of Queen's University of Belfast have made a discovery that may help to solve this problem. The study of 239 pairs with a diagnosis  "unexplained infertility" showed that in 80% of cases there was DNA damage in sperm.


A 51-year-old Brazilian has become a surrogate mother for her daughter

A 51 year-old resident of Brazil, Maria da Gloria gave birth to two twin girls for her daughter, who could not become mother because of the uterine amputation, that had been made to her at the age of 13. The Mother and the daughter had turned to fertility specialists 8 years ago, but they had refused to carry out IVF, referring to the sate of health and the age of Maria. However, six years later, the analysis showed that the health of the woman allowed her to carry and give birth to a child. Maria had got pregnant after the second attempt already, and 36 weeks later two perfectly healthy girls were born.

I usually have a negative attitude to the  IVF in the elderly age, not so much for medical (modern medicine makes it relatively safe to carry the pregnancy for a 50-year-old woman), but for social reasons (parents must not only bring a child into this world, but also to grow him up.)


Alimony from sperm donor

Only yesterday I commented on a new law on the sperm donation in the U.S. state of California, which provides an opportunity for single women to use the services of an acquainted donor instead of an anonymous one.

Despite the fact that before the insemination the woman must sign a document that waives any claims against the male donor, I have already raised some doubts about the Californian innovation. To be more precise, about whether such a refusal will have a real legal effect if the mother or a third party decides to go ahead to sue for recognition of paternity.
