· Growth hormone (GH), which is essential for growth · Thyroid stimulating hormone (TSH), which regulates thyroid function · Prolactin (PRL), which is essential for lactation · Follicle stimulating hormone (FSH) and Luteinizing hormone (LH), which are essential for ovulation in female animals and sperm production in male animals · Adrenocorticotroph hormone (ACTH), which stimulates the adrenal ...

Pausinystalia yohimbe (P. yohimbe) stem bark powder is commonly used as seasoning for barbecue beef in Nigeria and some West African countries. This study evaluated the effect of ingesting ethanol extract P. on hormones tissues linked with fertility female Wistar rats. A total fifteen adult rats weighing between 140 - 160g were this after an initial Acute Toxicity test was done to establish a s...

The effect of graded exercise on the secretion of cortisol, testosterone, prolactin, growth hormone, thyroid stimulating hormone (TSH), luteinizing hormone and follicle stimulating hormone (FSH) is reported. While cortisol, prolactin, growth hormone and testosterone rise during the period of exercise, a rise in luteinizing hormone becomes evident only after rest. Levels of FSH and TSH remained ...

OBJECTIVE Our purpose was to confirm the elevation of vaginal pH expected in patients with bacterial pathogens in premenopausal women and to examine the relationship of serum follicle-stimulating hormone and estradiol levels to vaginal pH in menopausal patients without and with hormone replacement therapy. STUDY DESIGN Vaginal pH was determined by phenaphthazine (Nitrazine) pH paper in 253 pa...

The influence of assay design and quantification system on assay performance was investigated by developing, optimizing, and comparing a time-resolved immunofluorometric assay (IFMA), an immunoenzymometric assay (IEMA), an immunoradiometric assay (IRMA), and a competitive radioimmunoassay (RIA), all performed with the same monoclonal antibodies (MCA) directed against human follicle-stimulating ...

The reason ovarian function and fertility are diminished in women with a low antral follicle count (AFC), despite significant numbers of follicles remaining in ovaries, is unknown. The bovine model is unique to address this question because cattle and women with a low AFC exhibit similar phenotypic characteristics including a diminished ovarian reserve, reduced circulating concentrations of ant...
