Follicle-Stimulating Hormone Glycobiology [PDF]

Endocrinology, 2019
FSH glycosylation varies in two functionally important aspects: microheterogeneity, resulting from oligosaccharide structure variation, and macroheterogeneity, arising from partial FSHβ subunit glycosylation. Although advances in mass spectrometry permit extensive characterization of FSH glycan populations, microheterogeneity remains difficult to ...

Effect of follicle stimulating hormone and testosterone on viability rate of cryopreserved spermatogonial stem cell after thawing [PDF]

The Iranian Journal of Veterinary Science and Technology, 2013
Stem cells are generally defined as clonogenic cells capable of both self-renewal and differentiation. Probably the best method for long-term preservation of spermatogonial stem cells is cryopreservation.

Discovery and Preclinical Development of Orally Active Small Molecules that Exhibit Highly Selective Follicle Stimulating Hormone Receptor Agonism

Frontiers in Pharmacology, 2021
An orally active follicle stimulating hormone receptor allosteric agonist would provide a preferred treatment for over 16 million infertile women of reproductive age in low complexity methods (ovulation induction-intrauterine insemination) or in high ...

Follicle-Stimulating Hormone Receptors in Oocytes? [PDF]

The Journal of Clinical Endocrinology & Metabolism, 2002
The regulatory mechanisms of oocyte maturation remain poorly understood. Although gonadotropins play a major role in these processes, they have generally been considered to act on somatic supportive cells, but not directly on germ cells. We have raised high affinity monoclonal antibodies against LH and FSH receptors.

Recombinant follicle stimulating hormone is effective in poor responders to highly purified follicle stimulating hormone [PDF]

Human Reproduction, 2000
Ovarian stimulation in cases of poor ovarian responsiveness is an important challenge in in-vitro fertilization (IVF) programmes. Despite improvements in oocyte number and quality, an ideal ovarian stimulation strategy has yet to be defined. Here, the results of ovarian stimulation with recombinant follicle stimulating hormone (rFSH) in 28 poor ...

Effect of FSH on testicular morphology and spermatogenesis in gonadotrophin-deficient hypogonadal mice lacking androgen receptors [PDF]

, 2010
Follicle stimulating hormone (FSH) and androgen act to stimulate and maintain spermatogenesis. FSH acts directly on the Sertoli cells to stimulate germ cell number and acts indirectly to increase androgen production by the Leydig cells.

Bioactive follicle-stimulating hormone [PDF]

Trends in Endocrinology & Metabolism, 1991
Abstract Specific and sensitive in vitro bioassays suitable for measurement of follicle-stimulating hormone (FSH) in small quantities of serum and urine have recently been validated. Comparisons of bioassay (B-FSH) potencies with immunoassay (I-FSH) estimates and chromatofocusing patterns have facilitated new discoveries regarding the regulation of ...

A simplified superovulation protocol using split-single administration of Folltropin®-V in hyaluronan: application to purebred sheep

Veterinární Medicína, 2018
Superovulation is an important step in assisted reproductive technology. Due to its short half-life, follicle stimulating hormone is usually given twice daily to ewes for three to five days, which is both time- and labour-intensive.
