Gestational age determination in pregnancies conceived via assisted reproductive technology

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 5, Page 604-612, May 2026.
ABSTRACT Objectives To compare gestational age (GA) dating models for pregnancies conceived via assisted reproductive technology (ART), assess whether 14 or 15 days more accurately reflects the median follicular‐phase duration in ART pregnancies and evaluate whether the gestational timelines of ART pregnancies are comparable with that of spontaneously ...

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders

Andrology, Volume 14, Issue 4, Page 1002-1016, May 2026.
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 ...

Luteinizing hormone receptor knockout mouse: What has it taught us?

Andrology, Volume 14, Issue 4, Page 1017-1028, May 2026.
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 ...

Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

Andrology, Volume 14, Issue 4, Page 978-991, May 2026.
Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.
