Low estrogen doses normalize testosterone and estradiol levels to the female range in transgender women

Clinics, 2018
OBJECTIVE: The ideal dosage of cross-sex hormones remains unknown. The aim of this study was to evaluate the luteinizing hormone, follicle-stimulating hormone, testosterone, estradiol and prolactin levels after low-dose estrogen therapy with or without ...

Genomic Insights into the Origin, High Fecundity and Environmental Adaptation of Hu Sheep

Advanced Science, EarlyView.
The Hu sheep diverged from the Small‐tailed Han sheep ≈1330 years ago, and subsequently migrated from northern to warm and humid southern regions. The genes BMPR1B, UNC5C, and GRID2 play a synergistic role in the superior reproductive traits of Hu sheep.

High physical activity and ovarian reserve: a prospective study of normo-ovulatory professional athletes

Journal of Ovarian Research, 2022
Background This study investigated whether high physical activity affects ovarian reserve in normo-ovulatory, reproductive-age women. Methods This prospective, observational study compared 31 professional female athletes, with 31 women who did not engage

Bioprinted Organoids: An Innovative Engine in Biomedicine

Advanced Science, EarlyView.
Bioprinted organoids refer to either the printing of stem cells into tissue shape and subsequent differentiate into organoids, or assembling induced organoids as bioinks to replicate native organ. It enables the creation of miniaturized organs with complex architectures and physiological functions, potentially enhancing reproducibility, throughput, and

Fractionation of the Swine Follicle Stimulating Hormone

Experimental Biology and Medicine, 1953
Summary1. A simple method has been developed for the recovery of FSH from residues resulting from the acid acetone extraction of swine pituitary glands. 2. The biological activity of the preparations obtained compare favorably with those of other investigators.

Alternative Models for Anticancer Drug Discovery From Natural Products Using Binary Tumor‐Microenvironment‐on‐a‐Chip

Advanced Science, EarlyView.
This study presents a binary tumor‐microenvironment‐on‐a‐chip (T‐MOC) system incorporating multicellular tumor spheroids (MCTs) as an alternative preclinical platform to evaluate the efficacy of anticancer natural products. The T‐MOC model reproduces in vivo drug delivery barriers and physiological conditions, enabling morphological analysis to predict

Disruption of Zebrafish Follicle-Stimulating Hormone Receptor (fshr) But Not Luteinizing Hormone Receptor (lhcgr) Gene by TALEN Leads to Failed Follicle Activation in Females Followed by Sexual Reversal to Males.

Endocrinology, 2015
Gonadotropins are primary hormones that control vertebrate reproduction. In a recent study, we analyzed the impacts of FSH and LH on zebrafish reproduction by disrupting FSH and LH-β genes (fshb and lhb) using transcription activator-like effector ...

Compound Heterozygous Variants in ZSWIM7 Gene Linked to Infertility and Its Role in Gonadal Development

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT This study aims to elucidate the role of the ZSWIM7 gene in the etiology of infertility, focusing on its potential association with premature ovarian insufficiency and azoospermia. We investigated an 18‐year‐old female patient who presented with primary amenorrhea, hypoplasia of the uterus and ovaries, Tanner stage II breast and pubic hair ...

Sex-specific regulation of follicle-stimulating hormone secretion by synaptotagmin 9

Nature Communications, 2015
The anterior pituitary releases six different hormones that control virtually all aspects of vertebrate physiology, yet the molecular mechanisms underlying their Ca2+-triggered release remain unknown.

A Splice‐Region Variant Causes an Atypical Presentation of GNAS Inactivation Disorder

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Pathogenic variants in GNAS can cause a wide range of diseases including pseudohypoparathyroidism, pseudopseudohypoparathyroidism, McCune‐Albright syndrome, among others. The specific phenotypic features that may be seen are influenced by the variant type and location in the gene, whether it causes loss or gain of function, and whether it is ...
