BACKGROUD Ovarian transplantation is a useful method for preserving the fertility of young women with cancer who undergo radiotherapy and chemotherapy. Follicle-stimulating hormone (FSH) is use to protect transplanted ovarian tissues from ischemia injury through promoting revascularization after transplantation, but the side effect of high level FSH is ovarian overstimulation leading to substan...

Abstract Background Prediction of ovarian response prior to the stimulation cycle is useful in determining optimal starting dose recombinant follicle-stimulating hormone (r-FSH). This study was designed (I) evaluate which following parameters (age, AMH, and FSH) can be used as a predictor GnRH antagonist protocol, (II) determine cutoff value AMH age for predicting poor high response, (III) inve...

Assay of frequently collected blood samples in four mature Hereford bulls indicated the existence of a tonic mechanism for the secretion of luteinizing hormone (LH) and follicle stimulating hormone (FSH), i.e., their episodic release was not observed. Increased plasma concentrations of LH and FSH, however, were obtained in response to an intravenous injection of 500 vg of gonadotropin releasing...

OBJECTIVE To measure testicular volume and the gonadotrophin response to gonadotrophin-releasing hormone (GnRH) stimulation in adolescents undergoing left varicocelectomy. PATIENTS AND METHODS Thirteen adolescents undergoing varicocelectomy had their testicular volume and endocrine function evaluated before and after surgery. RESULTS The initial left testicular volume was consistently small...

Introduction There has been a huge amount of media interest in the development of new home fertility tests for couples trying to conceive. The female fertility tests are marketed as devices that measure the quantity of healthy eggs women have left (ovarian reserve). Ovarian reserve is measured by determining the level of follicle-stimulating hormone (FSH) in the urine. High levels of FSH sugges...

Castrate Resistant Prostate Cancer (CRPC) is a difficult entity to treat in the spectrum of prostate cancer disease. Recently, Follicle Stimulating Hormone (FSH) has been shown to play an important part in the natural history of prostate cancer disease progression (Crawford et al., 2014). Here, we discuss a now deceased 94 year-old patient who illustrates the importance of this.

Pituitary gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) play central roles in regulating gametogenesis and the production of gonadal hormones, in fish as in other vertebrates. Pituitary gonadotropins are composed of two non-covalently associated polypeptide subunits, which must be glycosylated, folded, and assembled as a heterodimer to be biologically active. Si...

With the advent of recombinant follicle stimulating hormone (FSH) and luteinizing hormone (LH), free from contamination with each other (Loumaye et al., 1995), it is possible to dissect the individual contributions of FSH and LH to the regulation of ovarian function and to define optimal gonadotrophin usage in controlled ovarian hyperstimulation (COH) (Hillier, 1994). Basic and clinical researc...

The pituitary glycoprotein hormones, luteinizing hormone and follicle-stimulating hormone (FSH), act through their cognate receptors to initiate a series of coordinated physiological events that results in germ cell maturation. Given the importance of FSH in regulating folliculogenesis and fertility, the development of FSH mimetics has been sought to treat infertility. Currently, purified and r...

Plasma luteinising hormone (LH) and follicle-stimulating hormone (FSH) concentrations were measured before and after intravenous luteinising hormone-releasing hormone (LH-RH) in 33 boys with growth delay. Eighteen were prepubertal and 15 pubertal. Basal LH and FSH levels were low in both groups with mean increments after LH-RH of 3.2 +/- 0.8 U/l (mean +/- SEM) and 2.6 +/- 0.4 U/l respectively i...
