Energy intake is a critical determinant of reproductive performance in small mammals, particularly during energetically demanding periods such as lactation. Recent investigations have revealed that ...

A new article in Ecological and Evolutionary Physiology examines how the immune system and reproduction interact in female mammals, especially during pregnancy, from mating to birth. Lauren E.

The kisspeptin system is increasingly recognised as a central regulator of reproductive physiology in fish. Unlike mammals, teleosts often harbour two or more kisspeptin genes (e.g. Kiss1 and Kiss2) ...

Kisspeptin-10 is a peptide hormone that belongs to the kisspeptin family. Kisspeptin, a putative neuropeptide released by the hypothalamus, is hypothesized to elicit and initiate the release of ...

We studied condition and reproduction of moose (Alces alces) in southcentral Alaska using ultrasonography to determine rump-fat thickness and numbers of corpora lutea and embryos in early gestation, ...

WashU Medicine researcher Polina Lishko, PhD, a BJC Investigator and professor of cell biology and physiology, has shown in mice that sperm have a temperature-controlled switch that changes their ...

In polygamous mammals with strong competition, males generally die earlier than females due to battling other males for a ...

For generations, scientists have puzzled over why women tend to live longer than men. The gap — around five years on average ...

In mammals—including us humans—sperm are surprisingly picky about temperature, thriving best in conditions a few degrees cooler than normal body temperature. But, given that the female reproductive ...
