The scientists established that men’s sperm with age
obtains the properties, because of which increases the probability of appearing
of different anomalies in future posterity caused by genetic defects.
It is known that with age increases the risk of development
of autism, schizophrenia and other psychological disorders in successors.
The British scientists from the University Abertay suggested to create a
free sperm’s storage where young men who already reached 18 years could hand
over the sperm. Today this service is paid in Great Britain: so, the storage of
sperm in private institution will cost 200 pounds sterling (about 315 dollars).
“Thanks to various researches, conducted in recent
years, became evident the fact that early paternity favorably effects the
health of posterity. Thus, if men have an opportunity to freeze the sperm in
the age of 18, it will be possible to avoid genetic mutations” – doctor Kevin
tells.
However, the idea of Smith and his colleagues from the
University of Abertay has not been supported by other scientists who reminded
that the risks of possible diseases in children of fathers at mature age
are insignificant small and the spermatozoa being frozen for a long time
possess a smaller ability to fertilization.
Before an IVF cycle, medications are given to get the ovaries to produce more eggs. If you already have a reduced number of eggs or have elevated FSH levels, your body might not respond properly to IVF medications, which is not a good sign. The sperm and eggs both have specific receptors on their surface that allow for their interaction. However, barring chromosomal factors, sperm are usually not the among the reasons for failure of IVF. Because any quantitative or qualitative problems with the sperm are easily detected during semen analysis. In this case the patients are given the option of ICSI or IVF with donor sperm.
