estradiol receptors human testis receptor ontogenesis Leydig cell function human testicular disorders testicular cytosolic receptors
2009/2/20
Free cytoplasmic estradiol receptor was determined in testicular biopsies from six adults showing various primary testicular disorders, and in testicular tissue obtained at autopsy from 18 males of ...
Cytoplasmic extrusion and the switch from creatine kinase B to M isoform are completed by the commencement of epididymal transport in human and stallion spermatozoa
Maturity and function men stallions fertility cytoplasmic
2009/2/17
Although in several species there is a relationship between epididymal sperm transport and fertility, in human in vitro fertilization (IVF), spermatozoa recovered from the caput epididymidis or ev...
Leydig cell cytoplasmic content is related to daily sperm production in men
Leydig cell smooth endoplasmic reticulum
2009/2/6
The relationship between the abundance of specific Leydig cell organelles and daily sperm production (DSP) was determined. Testes from 10 men (26-53 years of age) were obtained at autopsy within 10 ...
