Human animals have a simple, direct system: copulation and sperm delivery may lead to fertilization of an egg, if the timing is right. Once a sperm joins an egg, the resulting zygote gets implanted on ...

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.

In most cooperatively breeding species, reproduction is monopolised by a subset of group members. However, in some species most or all individuals breed. The factors that affect reproductive success ...

I can’t predict the legal fate of abortion in the coming years, but there is one thing I am certain of from my studies of the animal world as an evolutionary biologist. Women won’t stop fighting for ...

The film "Reproduction Among Mammals" provides a detailed overview of the reproductive processes in mammals, particularly focusing on pigs. It describes the development of sperm in the testes, their ...

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) ...
