The nonprogressive motility of sperm populations from mice with a tw32 haplotype
nonprogressive motility sperm populations mice tw32 haplotype
2009/2/19
We have previously reported that epididymal spermatozoa from mice carrying a tw32 haplotype have a lower net velocity than do spermatozoa from congenic +/+ males. Using a test for nonprogressive mot...
In vitro sperm-binding assay to distinguish differences in populations of human sperm or damage to sperm resulting from cryopreservation
Sperm quality fresh versus frozen semen
2009/2/18
Annually, >1.3 million men are members of couples seeking help because of infertility. Semen from many of these men contains reasonable numbers of motile and normal sperm, but for a subset of indivi...
Effect of chorionic gonadotropin and flutamide on Leydig cell and macrophage populations in the testosterone-estradiol-implanted adult rat
chorionic gonadotropin Leydig cell macrophage populations testosterone-estradiol-implanted adult rat
2009/2/17
The objective of this study was to investigate the role of androgens and nonandrogenic Leydig cell products in maintaining Leydig cell and macrophage numbers in the testis of the adult rat. Adult ...
The effects of gonadotropin-releasing hormone immunization and recombinant follicle-stimulating hormone on the Leydig cell and macrophage populations of the adult rat testis
Stereology morphometry optical disector leucocytes
2009/2/17
The objective of this study was to investigate the role of the gonadotropins and, in particular follicle-stimulating hormone (FSH) in maintaining the Leydig cell and macrophage populations of the adul...
Preparation and short-term culture of enriched populations of guinea pig spermatocytes and spermatids
spermatogenesis spermatocyte spermatid
2009/2/6
In order to study acrosome biogenesis in vitro, the authors developed techniques for the isolation and culture of enriched populations of guinea pig spermatogenic cells using a modification of the t...
Single-Nucleotide Polymorphisms and Mutation Analyses of the TNP1 and TNP2 Genes of Fertile and Infertile Human Male Populations
Protamine transition nuclear protein sperm male infertility genome promoter SNPs
2008/12/23
Previously, we examined the relationship between protamine gene variations and human male infertility. In this study, we show specific variability in the transition nuclear protein genes (TNPs) of...
