No defects found in reproductive ability of male mice returning from short stay in space

Male mice raised in space using specially developed cages were returned safely to Earth. The sperm production/fertilizing ability of the mice were normal and the reproduction ability of the offspring were not affected by their parents' stay in outer space. The findings on the effects of the environment in space on the male reproductive system will contribute to the accumulation of basic knowledge for humankind to expand the range of its activity to space.

Struggling with infertility? You are not alone. Infertility affects one out of every six Canadian couples. Some resort to in vitro fertilization, with mixed results. In a new study, researchers unveiled a mechanism that likely contributes to the low level of pregnancy success in some fertility clinics. This new information could ultimately increase women's chances of having a baby.

Point-of-care diagnostic for detecting preterm birth on horizon

A new study provides a first step toward the development of an inexpensive point-of-care diagnostic test to assess the presence of known risk factors for preterm birth in resource-poor areas. The study found that measuring levels of TIMP-1 and D-lactic acid in vaginal secretions may be a noninvasive, cost-effective way to assess the risk for preterm birth due to a short cervix and microbiome composition.

For the first time, researchers have created mouse blastocyst-like structures, or 'blastoids,' from a single cultured cell. The work could help advance research into development as well as inform issues around pregnancy, infertility, or health problems later in the offspring's life.

Did early mammals turn to night life to protect their sperm?

Humans are diurnal — we are active in the day and sleep at night. But diurnalism is by far the exception rather the rule in mammals. About 250-230 million years ago, the mammalian ancestors, called the therapsids, became exclusively nocturnal, and stayed so until the demise of the dinosaurs 66 million years ago.
