An explanation is
found throughout the cold: . Winter is, in Sapiens, the mating season 1Because the figures of the National Institute of Demographic Studies (INED) show unambiguous: the period when more children
are born from July to October, with a peak in September.
Especially around
23 September, where births are twice as likely than a normal day, but that peak
one has a very special explanation, since it corresponds to concepts of Eve,
the night of New Year festivities !
Apart from this feast
day , simply subtract nine months birthday to find
that lots of little Jesus are designed in winter. Because it is cold and
couples looking to keep warm in the arms of one another?
Science, which
never satisfied appearances, has recently been a much better explanation! One
explanation lies in one word: sperm. For Israeli researchers made the
finding that male reproductive cells have a strong preference for the winter
season: it makes them strong ...!
That was in 2013, at University
Medical Center Soroka (Beer-Sheva, Israel) . The protocol? It covered nearly 6500 samples of sperm of
men who had consulted the procreation aid department with their partner.
MORE SPERM, BETTER TRAINED AND MORE MOBILE
The result ? In
winter, in healthy men, the sperm were more numerous, better trained and more
particularly mobile! This last feature is crucial since only a very small
number of sperm can swim fast enough to reach the egg of the mother.
However, while in
spring and summer, these high-performance swimmers were only 3.5 to 4% in the
samples studied, in the fall, they reached 4.9% and 5% ... in winter! An
increase of 43% compared to the spring.
Who would have
suspected that male gametes are at their best in the cold season! But the
facts are there: winter is conducive to reproduction, paternal side. And
logically, births registered in the same Israeli hospital were significantly
higher in the months from July to October, nine months after the cold season.
CHANGES IN THE SUNSHINE COULD BE THE CAUSE OF THE PHENOMENON
Of course, one question burns the lips: what may well hold this seasonal
variation in sperm quality?Las biologists do not really explain. However,
as noted by Dr. Jacques Auger, reproduction biologist at the Cochin Hospital (Paris) , the phenomenon is known since the early 2000s!
A study published
in 2001 and conducted in several European cities (Paris, Edinburgh, Copenhagen
...), but on a smaller number of men in the Israeli study had found a better
sperm quality winter: sperm concentrations were 30% higher than it was!
"This could
be due to variations in sunshine
during the season , which
would influence the hormones and so on sperm production ... but there is still
no proof" , explains the
researcher.
Better
understanding these mechanisms would however be useful, especially for couples
struggling to have a child. In France, they account for nearly one in five
couples.

Woww, that's interesting to hear. Thank for sharing. I've never heard about this before to look into. Though this would not be any way out for us. I cannot physically bear pregnancies. I just loose them at early terms..We had to seek help from the surrogate. Used Ukrainian Biotexcom for this. Have no a single word of regret.
ReplyDeleteWell, ivf is costly depending on a country/clinic you're with. Choosing a country for fertility treatment you might consider the following: Does the country legally allow the treatment you require? Do you fall within the legal age limit? Does the country have laws regarding who they can treat? Are there easy and cheap transport links to that country? Is there robust IVF regulation in place? Are you happy with the laws on anonymity for donors? Is the potential cost of treatment within your budget?
ReplyDeleteThere are lots of choices. For example, for some people using a small clinic is preferable as the staff might be able to give more personalised care. For others, a large busy clinic able to provide a wide range of treatments would provide them with more choices. There are just too many factors to compare, so it's crusial to think about what’s important to you and focus on that.
We chose the guaranteed package of 5 ivf shots for 10k roughly. The package price covers everything ouside the plane tickets. All services and meds included.
Quite interesting to know. Thanks for sharing. I've never thought seasons effect the 'male power'. Though obviously they do! Unfortunately trying this very thing was/is out of the question for us as our case is too complicated to cut long story short. We had to use different fertility treatment options. Were finally successful with Biotexcom.
