The ecology of gestational growth in a wild cooperative mammal
Journal of Animal Ecology, EarlyView.Using data from hundreds of wild pregnant meerkats, Thorley et al show that gestational growth varies widely, is shaped by nutrition but not social conditions, and improves pup survival without shortening telomeres. The fitness consequences and limited flexibility of prenatal growth likely enhance selection on early postnatal growth plasticity ...

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders
Andrology, EarlyView.Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

Assessing the Value of Coordinated Sire Genetics in a Synchronized AI Program [PDF]
Synchronized artificial insemination was used to inseminate cows using different types of sire genetics, including low-accuracy, calving-ease, and high-accuracy. These three calf sire groups were compared to calves born to cows bred using natural service.

Luteinizing hormone receptor knockout mouse: What has it taught us?
Andrology, EarlyView.Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

Andrology, EarlyView.Abstract Background Predicting male fertility in farm animals remains a challenge. Seminal plasma (SP) contains a high amount of heterogeneous seminal extracellular vesicles (sEVs), believed involved in reproductive processes and maybe key to understanding male fertility.
