Bioassays of Follicle Stimulating Hormone
Endocrine Reviews, 1988With the availability of these highly sensitive in vitro assays, measurement of bio-FSH in serum and urine becomes possible. Clinical studies have been done to investigate the role of bioactive FSH in different physiological and pathological conditions. There are however problems with these assays.

Neuroendocrinology, 2008
Injection of ovine follicle-stimulating hormone (o-FSH) into the third cerebral ventricle significantly suppressed plasma luteinizing hormone (LH) release in conscious, unrestrained ovariectomized rats. Intraventricular injection of o-FSH (0.5 µg) significantly lowered the plasma levels of LH by 70 min and decreased pulse frequency, whereas the ...

ORAL CONTRACEPTIVES AND FOLLICLE-STIMULATING HORMONE
The Lancet, 1968The authors report the effects of an oral contraceptive on plasma levels of follicle-stimulating-hormone (FSH) as measured by a double-antibody method of radioimmunoassay. Reichert 780 pituitary FSH labelled with iodine-131 and rabbit antihuman FSH serum were used with the International Reference Preparation number 2 of human menopausal gonadotrophin ...

Endocrinology, 1979
Highly purified FSH was obtained from several batches of bovine pituitaries by sequential application of the following procedures: 1) extraction with an alcoholic sodium acetate buffer, 2) fractionation with metaphosphoric acid, 3) fractionation with ammonium sulfate, 4) gel filtration on Sephadex G-150, 5) ion exchange chromatography on CM-Sephadex, 6)

Spurious elevation of follicle‐stimulating hormone
Acta Obstetricia et Gynecologica Scandinavica, 1992Serum concentrations of follicle‐stimulating hormone (FSH) were measured in a 33‐year‐old eurnenorrhoeic woman with primary infertility. Postmenopausal levels were obtained. Using an alternative assay, the patient was found to have normal levels of FSH. The probable cause of the misleading result is discussed.

Norepinephrine in Graafian Follicles Is Depleted by Follicle-Stimulating Hormone*
Endocrinology, 1982The purpose of the present study was to measure norepinephrine (NE) in Graafian follicles and correlate changes in its concentration with circulating gonadotropins secreted endogenously or administered exogenously. Graafian follicles were removed from the ovaries of adult cycling rats. The follicles were pooled in groups of 10-13, and NE was determined

Follicle-Stimulating Hormone and Advanced Follicle Development in the Human
Archives of Medical Research, 2001The great majority of human oocytes is destined to undergo atresia. Only follicles able to respond to stimulation by follicle-stimulating hormone (FSH) will enter the final stage of development and ovulate. While the role of FSH in early follicle development is unclear, late follicular development is FSH-dependent.

About 15 % of all couples experience infertility at some time during their reproductive lives. Nowadays, infertility can be treated by the use of assisted reproductive technologies (ART), such as in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI).

Immunology of Follicle-Stimulating Hormone and Luteinizing Hormone
1970Publisher Summary This chapter discusses immunology of follicle-stimulating hormone and luteinizing hormone. Although great strides have been made in the last few years due to the introduction of modern physiochemical techniques, absolute purity of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) has not yet been attained.
