Abnormal findings in testicular tissue of COVID-19 patients, SARS-CoV-2 mostly undetected

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused over 9.263 million cases and taken more than 477,000 lives as of June 24, 2020 – just six months after the initial outbreak in Wuhan, China, was reported. The illness, called COVID-19 disease, caused by SARS-CoV-2 is a severe pneumonic illness, caused by the entry of the virus into the type II alveolar cells.

Women with a history of miscarriage or subfertility more likely to have mild thyroid abnormalities

The egg decides which sperm fertilizes it

There is ample evidence to show that as millions of human sperm cells swim towards a waiting ovum or egg, only one gets to fertilize it. Now, a new study shows that even though the fastest and most capable sperms reach the ovum first, it is the egg that has the final say on which sperm fertilizes it. The study titled, "Chemical signals from eggs facilitate cryptic female choice in humans," is published in the latest issue of the journal Proceedings of the Royal Society B.

Neanderthal gene in women boosts infertility

It is still unclear why some women go into labor for long periods, and some face a high risk of childbirth. Also, some women fall pregnant quickly, while others may take years before they conceive. The answer may be due to a gene inherited from the Neanderthals, an extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ago.
