Gestation vs Pregnancy.
Some may be surprised at the success rate of viable conceptions in humans. -
How the virus that causes COVID-19 can infect and damage the placenta.
Using a cell model SARS-CoV-2 infection caused significant reduction in the survival and differentiation of syncytiotrophoblast cells, which led to lower production of the human chorionic gonadotropin hormone (hCG) - needed for early pregnancy maintenance.

A nice Preprint paper to start off the year on the placenta and shared developmental pathways with the heart.
Authors: "the molecular and physiological associations between the embryonic heart and developing placenta are increasingly evident"
The authors "review the clinical, structural, and molecular relationships between congenital heart defects (sic) and placental dysfunction..."

Quite a finding with implications for litter bearing species.
Key point: "A crucial finding was the greater variability in both primordial follicles in the ovaries from females derived from male-biased litters and stromal cell count in the endometrium of females from male- and female- biased litters. This could be inflating the variability of reproductive success seen in females from male-biased litters."
