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 ...

Effects of Exogenous Supplementation of Progesterone on Conception Rates in Lactating Murrah Buffaloes

Veterinary Sciences
The objective of this study was to deduce the effect of exogenous supplementation of progesterone as an intramuscular injection at the time of artificial insemination (AI) on time of ovulation and conception rate in lactating Murrah buffaloes. A total of

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 ...

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

Andrology, EarlyView.
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.

What Moves Men to Change? A Mixed‐Methods Study on Facilitators and Barriers of Lifestyle Changes in Men Seeking Fertility Care

Andrology, EarlyView.
ABSTRACT Background An unhealthy lifestyle negatively affects male fertility. Despite this, men that are part of an infertile couple often fail to improve their lifestyle and evidence on influencing factors is limited. Objectives To identify facilitators and barriers involved in lifestyle changes of men seeking fertility care and in lifestyle ...

Microtubule Inner Protein CFAP77 Contributes to Sperm Motility and Male Fertility in Mice

Andrology, EarlyView.
ABSTRACT Background Sperm motility is essential for male fertility, and its regulation is dependent on the structural integrity of the axoneme. The axoneme consists of a conserved “9+2” microtubule arrangement and is supported by microtubule inner proteins. However, the functional significance of many microtubule inner proteins remains unclear.

Testicular SIRT1 Loss Reveals an Aging‐Like Proteomic Landscape and Precipitates Reproductive Deterioration

Andrology, EarlyView.
ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.

Is it safe to preserve uterus after live birth following progestin‐based fertility‐sparing treatment for endometrial cancer or atypical hyperplasia: A long‐term retrospective cohort study

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Achieving live birth following fertility‐sparing treatment is associated with improved recurrence‐free survival among patients with endometrial cancer/atypical endometrial hyperplasia. Abstract Introduction We aimed to assess the safety of continuous uterus‐preserving treatment among patients with endometrial cancer (EC) and atypical endometrial ...

Discrepancy in menstrual and ultrasound‐based gestational age is associated with chromosomal aberrations and adverse pregnancy outcomes—Results from a nationwide cohort study

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
A smaller than expected crown–rump length (CRL) relative to last menstrual period was strongly associated with increased risk of chromosomal abnormalities, adverse pregnancy outcomes, and obstetric complications. Conversely, a larger than expected CRL was associated with a reduced risk of these outcomes.
