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.

Effects of Interleukin-6 (IL-6) on In Vitro Cultured Equine Chorionic Girdle Cells

Animals
Introduction: Equine chorionic girdle cells can give rise to the endometrial cup, a structure that secretes equine chorionic gonadotropin (eCG). To date, the mechanisms underlying the proliferation, differentiation, invasion, and hormone secretion of ...

The threshold of estradiol level for fresh embryo transfer differs between blastocyst and cleavage‐stage embryo

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Our results suggested that the difference in pregnancy outcomes between fresh and frozen embryo transfer is related to the peak estradiol level and embryo transfer stage. The cutoff values for peak estradiol level for performing freeze‐all strategy to improve pregnancy outcomes were different for cleavage‐stage and blastocyst‐stage embryo transfer ...

A comparative study to estimate three commercial products of human chorionic gonadotropin (hCG) on blood biochemistry, sexual hormones concentrations, reproductive indices, and larvae production of African catfish Clarias gariepinus brood-stock

Italian Journal of Animal Science
Currently, almost all hatcheries that produce catfish seeds depend on hormone stimulations, application of human chorionic gonadotropin hormone (hCG) is considered the common method for commercial spawning of African catfish Clarias gariepinus ...

Transcription Factor TCF12‐Mediated Maternal Gene Expressions in Mouse Oocyte Are Prerequisites of Successful Fertilisation and Zygotic Genome Activation

Cell Proliferation, EarlyView.
Maternal TCF12 ensures the competence of fertilisation by controlling the expression of Astl and the proper location of cortical granules. Furthermore, maternal TCF12 maintains the phosphatase activity of PP2A by regulating the expression of Arpp19. Oocyte‐specific deletion of Tcf12 leads to fertilisation defects as well as ZGA failure at the 2‐cell ...

Single‐dose pharmacokinetic study comparing the pharmacokinetics of recombinant human chorionic gonadotropin in healthy Japanese and Caucasian women and recombinant human chorionic gonadotropin and urinary human chorionic gonadotropin in healthy Japanese women

Reproductive Medicine and Biology, 2018
Purpose Recombinant hCG (r‐hCG) was approved in Japan in 2016. As a prerequisite for a Phase III study in Japan related to this approval, the pharmacokinetic (PK) profile of r‐hCG was investigated. Methods An open‐label, partly randomized, single‐center,

Mechanistic Insights Into Recurrent Implantation Failure: The Lactate–H3K18la–SLC7A11 Axis Explored via Endometrial Organoid and Blastoid–Endometrial Cell Implantation Models

Cell Proliferation, EarlyView.
Clinical samples first revealed impaired lactate synthesis in RIF patients. Subsequently, using endometrial organoids and a blastoid‐endometrial cell implantation model, we demonstrated that lactate enhances endometrial receptivity via H3K18la‐mediated SLC7A11 activation.
