Impaired estrogen production by Leydig cells of the naturally retained testis in unilaterally cryptorchid boars and stallions
testis cryptorchid boar stallion estrogens
2009/2/23
Estrogen production in vitro was compared for Leydig cells from cryptorchid and scrotal testes in boars and stallions. Animals with natural and experimental cryptorchidism were used. Purified Leydig...
Involvement of endothelial nitric oxide synthase in the impaired endothelium-dependent relaxation of cavernous smooth muscle in hypercholesterolemic rabbit
Hypercholesterolemia cavernous smooth muscle
2009/2/18
The present study was designed to evaluate whether functional impairment and/or protein expression of constitutive nitric oxide synthase (cNOS; endothelial NOS [eNOS] and neuronal NOS[nNOS]) was i...
Testosterone-dependent restoration of spermatogenesis in adult rats is impaired by a 5alpha-reductase inhibitor
Testosterone-dependent restoration spermatogenesis adult rats 5alpha-reductase inhibitor
2009/2/18
Germ cell development (spermiogenesis in particular) in the adult rat is known to be testosterone dependent. Recently we proposed a role for the 5alpha reduction of testosterone to dihydrotestostero...
Deficiency of fucosidase results in acrosomal dysgenesis and impaired sperm maturation
Fucosidosis spermatogenesis epididymis dog
2009/2/17
Although a variety of glycosyltransferases and glycosidases have been implicated in spermatogenesis and posttesticular sperm maturation, the biological role of these enzymes in these processes is larg...
Impaired germ cell development in the testes of immature rats with neonatal hypothyroidism
Gonocyte Sertoli cell thyroid hormone stereology optical disector germ cell number
2009/2/17
The induction of neonatal hypothyroidism from day 1 to day 25 postpartum using 6-propyl-2-thiouracil (PTU) resulted in a 45% and 77% reduction of testis weight on days 20 and 30, respectively, and a...
Impaired secretory function of the prostate in men with oligo-asthenozoospermia
Seminal plasma infertility PSA seminal vesicles
2009/2/13
The secretory function of the human prostate and the seminal vesicles is a prerequisite for gel formation and liquefaction of semen, but the relation to poor sperm motility and low sperm count in ...
Impaired seminal antioxidant capacity in human semen with hyperviscosity or oligoasthenozoospermia
Superoxide dismutase catalase total antioxidant status
2008/12/29
Antioxidant capacity of seminal plasma was evaluated in 120 semen samples subdivided into asthenozoospermic and oligoasthenozoospermic specimens with normal consistency and into asthenozoospermic an...
Screening for AZF deletion in a large series of severely impaired spermatogenesis patients
AZF deletion severely impaired spermatogenesis patients
2008/12/25
Recent investigations have pointed to a high prevalence of Y chromosome submicroscopic deletions in men with severely impaired spermatogenesis. We report on the incidence in 128 infertile men, in wh...
Impaired Sperm Function After Spinal Cord Injury in the Rat Is Associated With Altered Cyclic Adenosine Monophosphate Signaling
cAMP SYBR-14 JC-1
2008/12/23
Our previous observations of changes in the expression of cAMP-dependent genes and the cAMP-responsive element modulator (CREM) in rat testicular cells after spinal cord injury (SCI) implied abnor...
