Gonadotropins in insects: An overview

, 2001
Control of gonad development in insects requires juvenile hormone, ecdysteroids, and a peptidic brain gonadotropin(s). Compared to vertebrates, the situation in insects with respect to the molecular structure of gonadotropins is far less uniform ...

Analysis of High‐Risk Factors for Failure of Bleeding Control in Enhanced Myometrial Vascularity Treated With Uterine Artery Embolization

Journal of Clinical Ultrasound, EarlyView.
Enhanced Myometrial Vascularity (EMV) is a serious gynecological condition that often leads to abnormal uterine bleeding. Malformation size and involvement of the uterine fundus are significant risk factors. If EMV diameter > 3.85 cm, the bleeding of the patient is more likely to result in failure in UAE treatment.

The use of recombinant FSH in combination therapy in a young male with idiopathic hypogonadotropic hypogonadism

Медицинский совет, 2018
Currently, testosterone drugs are used to treat hypogonadotropic hypogonadism, which allow men to get a good height and reach a stage of sexual development corresponding to their age.

Cultured granulosa cells produce two plasminogen activators and an antiactivator, each regulated differently by gonadotropins

, 1985
Although treatment of cultured granulosa cells with gonadotropins increases their fibrinolytic activity, the biochemical nature of this effect is unclear.

First‐Trimester Crown‐Rump Length and Large for Gestational Age Newborns: What Correlation?

Journal of Clinical Ultrasound, EarlyView.
Our research found for the first time that uneventful pregnancies with LGA neonates are characterized by larger than expected CRL at the first trimester. CRL is one of the new markers that can be used to early identify fetuses at risk of increased fetal growth.

Evaluating Sperm Recovery Time and Efficacy of Monotherapy vs. Combination Therapies in Men with Congenital Hypogonadotropic Hypogonadism: A Systematic Review and Meta-Analysis

The World Journal of Men's Health
Purpose: There is a lack of pooled data exploring the time and rates for human chorionic gonadotropin (hCG) monotherapy vs. combination therapies (hCG+human menopausal gonadotropin or recombinant human follicle-stimulating hormone) to restore ...

Monitoring Changes in Sperm Concentration and Quality Help Improve Captive Breeding Outcomes of the Endangered Amphibian Rawlinsonia littlejohni

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Amphibians are among the most threatened taxonomic groups, with many species experiencing rapid declines that have resulted in small, isolated populations vulnerable to inbreeding depression and reduced fertility. One major outcome of inbreeding is lowered fecundity, often linked to morphological changes in gametes.
