Pituitaries were collected from intact rams and rams that had been rendered bilaterally cryptorchid by surgery to examine the effects of cryptorchidism on gonadotropin heterogeneity, levels of uncombined luteinizing hormone (LH) subunits, and the apparent molecular sizes of LH and follicle-stimulating hormone (FSH). Cryptorchid rams had higher pituitary contents of LH and FSH as well as reduced...

Follicle-stimulating hormone (FSH; follitropin) is a pituitary glycoprotein composed of two post-translationally modified subunits, which must properly assemble to be biologically active. FSH has been difficult to purify and to obtain in quantities sufficient for detailed biochemical studies. We have targeted FSH expression to the mammary gland of transgenic mice by using cDNAs encoding the bov...

High serum follicle stimulating hormone (FSH) values are consistent with ovarian failure. We studied the progress of 67 women aged under 35 years with oligomenorrhoea or secondary amenorrhoea in whom the serum FSH value was greater than 20 U/1. Twenty-four patients remained amenorrhoeic, but 17 ovulated and six conceived, two on two occasions. Coincident mean serum luteinising hormone (LH) conc...

background: estradiol (e2) is required for follicular development and play an important role in embryo implantation. objective: the aim of this study was to assess the impact of serum e2 levels on the day of hcg administration in ivf-icsi patients who are performed controlled ovarian hyperstimulation (coh). materials and methods: a total of 203 women who were undergone one time ivf cyclus were ...

ObjectiveTo characterize circulating insulin-like factor 3 (INSL3) in different stages of ovarian insufficiency and its role the evaluation premature (POI).DesignRetrospective cohort study.SettingUniversity-based center for reproductive medicine.Patient(s)A total 145 women, including 48 patients with POI (25 IU/L < follicle-stimulating hormone [FSH] ?40 IU/L), 49 biochemical (bPOI) (10 FSH ?25 ...

Purpose: To evaluate the effects of leuprorelin plus growth hormone on serum luteinizing (LH), follicle-stimulating (FSH), and estradiol (E2) levels in children with idiopathic central precocious puberty. Methods: A total 102 girls puberty who met inclusion criteria between April 2020 September 2021 were enrolled this study, assigned randomly to either a control group given only, or combined tr...

Methods: Five beagle bitches were administered MPA subcutaneously at 10 mg/kg, every four weeks. A combination of corticotropin-releasing hormone (CRH), growth hormone-releasing hormone (GHRH), gonadotrophin-releasing hormone (GnRH), and thyrotropin-releasing hormone (TRH) was administered before and 2, 5, 8, and 11 months after the initial MPA treatment. Blood samples for determination of plas...
