Support for the claim appears to rest on explicit birth records, although interviews with families in the village were also conducted. The New York Post writes (emphasis mine) According to birth records, there hasn’t been a boy born there since 2009, though 12 girls have come into the world in that time frame. I did some digging and was unable to access ...

Generally if such statistics would exist, they would be available to every Polish citizen per freedom of information act. Alas, there are no such statistics in Poland. While the claim might be true, citing birth records is a sure sign of a fake. I know well which sources are available and who can get it, because I've worked for years as a reporter in Poland. ...

No, it takes more than one sperm. The egg has multiple barriers which take up to 100 sperm, co-operating, to penetrate. The fusion of the egg with its three barriers (cumulus-oocyte complex, zona pellucida and finally the plasma membrane) takes approximately 10 sperm to clear the first two barriers of the oocyte referring to De Jonge and up to 100 sperm to ...

Yes. Homo sapiens is, as far as we know, the only species that has permanently enlarged breasts. In the rest of the primates, plump breasts last only as long as breastfeeding does: Humans are the only primate to have breasts that are enlarged at all times, in contrast to other primates which have swollen breasts only when breastfeeding. This ...

This says that the claim is a "popular Greek view" followed by Aristotle: Contrary to a popular Greek view, which regarded the father alone as providing seed, a view that would be followed by Aristotle (Lloyd 1983, 86 ff.), Alcmaeon may have argued that both parents contribute seed (DK, A13) and that the child takes the sex of the parent who contributes ...

According to American Pregnancy it looks really improbable. Similar statements are made on the Oakland University website and on this website about contraception (which explicitly states it's impossible). The girls should have been swimming naked and the "father" should have ejaculated just outside her vagina as sperm would be killed in a few second in the ...

Yes it is possible. See Father's Milk Discover February 1995. We’ve known for some time that many male mammals, including some men, can undergo breast development and lactate under special conditions. ... Breast development occurs commonly, and spontaneous lactation occasionally, in men under conditions of starvation. Thousands of cases were ...

This is not my area of scientific expertise. I cannot say if this study by Wilder et al is correct or not, but I can read the study and compare their conclusions to Baumeister's. Wilder et al conclude that women outnumber men in human ancestry, but they do not conclude that the ratio is two to one. They make a different conclusion about a two to one ratio, ...

This is absolutely true. The theory is called Preformationism, and was widely (though not exclusively) believed in some form from Ancient Greek times until the 17th century. Pythagoras and Aristotle are among the philosophers associated with this theory. Some qualifications: spermatozoa were not known to exist until the invention of the microscope. However ...

No. And actually, there is no claim. That is just a misunderstanding. And one that does not make any sense in terms of human reproductive functions. If orgasm would trigger menstruations way out of the normal cycle than successful implantation of the fertilised egg would very seldom occur and no population would exist to propagate this idea. How is a ...

Induction of labour in women with intact membranes reduces the risk of caesarean section. Per a systematic review and meta-analysis of trials in women with intact membranes in 2014 by Wood S et.al. for the question 'Does induction of labour increase the risk of caesarean section?', the authors conclude that in clinical trials of induction of labour versus ...

The woman's biorhythm cycle which is the primary basis for Smart Storks unique gender selection program is described by scientists to be pseudoscience and also an examination of 134 biorhythm studies in 1998 found that the theory is not valid.

In humans, the X-bearing sperm has 2.8% more total DNA than Y-bearing sperm. Thus, when stained with a DNA-specific fluorochrome, the fluorescent signal emitted by an X-bearing sperm is greater than that emitted by a Y-bearing sperm which is utilized in the Microsort method for gender selection. Male conceptuses are less viable than female and the ratio of ...

Research referred by Emily Martin in her 1991 paper 'The Egg and the Sperm: How Science Has Constructed a Romance Based on Stereotypical Male Female Roles' show that the sperm and egg are mutually active partners who do interact on more mutual terms. There is a take 2 for the egg and the sperm tale coming up with Richard Cone according to her CV present here....

The idea that a man contributed the seed and a woman was a "container" was prevalent in the ancient world, as it has been noted above. It's even part of Apollo's main argument in the final play of the Oresteia trilogy from 458BCE. However, like now, there was not one single theory to describe nature that everyone believed. The Hippocratic Treatises ...

Sperm are intricately adapted to existing alongside millions of their peers at all times, but is simply unknown if they can survive and achieve success without these peers. There simply is not enough research to know. Specifically, no one has ever tried a series of billions of trials in which they introduced a single sperm and checked if it created a ...
