Seminal vesicles are novel sites of luteinizing hormone/human chorionic gonadotropin-receptor gene expression
LH/hCG receptors male accessory organs gonadotropins
2009/2/17
The hypothesis that rat seminal vesicles may contain luteinizing hormone (LH)/human chorionic gonadotropin (hCG) receptors was tested by means of a number of different techniques. Northern blotting ...
Enhanced susceptibility of follicle-stimulating-hormone-deprived infertile bonnet monkey（Macaca radiata）spermatozoa to dithiothreitol-induced DNA decondensation in situ
Enhanced susceptibility follicle-stimulating-hormone-deprived infertile bonnet monkey dithiothreitol-induced DNA decondensation

Copulatory behavior and fertility in transgenic male mice expressing human placental growth hormone gene
Sexual behavior placental growth hormone variant
2009/2/17
Male transgenic (TG) mice overexpressing the human placental growth hormone (GH) variant gene (hGH-V) exhibit reproductive deficits in spite of normal testosterone levels and normal sperm counts. ...
Hormone treatment after irradiation stimulates recovery of rat spermatogenesis from surviving spermatogonia
