Modulation of insulin-like growth factor-1 in the seminal plasma of infertile men
Modulation insulin-like growth factor-1 seminal plasma infertile men
2009/2/18
It has been suggested that insulin-like growth factor (IGF)-1 plays an important role in the regulation of spermatogenesis in the testes. In the present study, concentrations of total IGF-1 we...
The effects of antifreeze peptide III (AFP) and insulin transferrin selenium（ITS）on cryopreservation of chimpanzee（Pan troglodytes）spermatozoa
Semen acrosome CAMA FITC-PSA
2009/2/17
We investigated the effects of antifreeze peptides (AFP) and insulin transferrin selenium (ITS) on the motility and membrane integrity of chimpanzee (Pan troglodytes) spermatozoa after chilling (0...
Immunohistochemical localization of insulin-like growth factor I（IGF-I）in the rat epididymis
Immunohistochemical localization insulin-like growth factor I（IGF-I） rat epididymis
2009/2/12
The distribution of insulin-like growth factor I (IGF-I) was studied by immunohistochemistry during postnatal development of the rat epididymis. At 2 weeks the immunoreactivity was mainly located al...
Insulin-like growth factor 1, but not growth hormone, has in vitro proliferative effects on neonatal foreskin fibroblasts without affecting 5-alpha-reductase or androgen receptor activity
5-a-Reductase androgen receptor micropenis
2009/2/11
Clinical observation of patients with congenital growth hormone (GH) deficiency and Laron-type dwarfism suggests that factors such as GH or insulin-like growth factor 1 (IGF-1) might in addition to ...
Binding of methyltrienolone to androgen receptors in human skin fibroblasts is enhanced by insulin
R1881 cycloheximide actinomycin D DNA protein
2009/2/10
Previous reports have suggested a relationship between hyperinsulinemia and increased androgen secretion leading to female virilization, but no report has been made of the effects of insulin on an...
Effects of insulin-like growth factor-I on androgen production by highly purified pubertal and adult rat Leydig cells
Somatomedin-C development steroidogenesis
2009/2/10
Leydig cells were isolated and purified from adult and midpubertal rats to study the effects of insulin-like growth factor-I (IGF-I) on steroidogenesis. Androgen production, as measured in Leydig ce...
Insulin-Dependent Diabetes Affects Testicular Function by FSH- and LH-Linked Mechanisms
Testes follicle-stimulating hormone luteinizing hormone
2008/12/22
A study was conducted to form a unified hypothesis regarding the gonadotropin-related mechanisms that underlie alterations in the male reproductive system in individuals with diabetes. Streptozotoci...
