In brief Mating shuts down the 2-methoxyestradiol (2ME) nongenomic pathway that accelerates oviductal egg transport in the rat. This study shows that sperm cells, but not vaginocervical stimulation, utilize TNF-α to shut down this 2ME nongenomic pat

Cathecolestrogens are estradiol metabolites produced during folliculogenesis in the mammalian ovary. 2-Hydroxyestradiol (2-OHE2) is one of the most abundant although its role remains unknown. The aim of this study is to investigate whether the presen

Summary Several observational studies have showed a combination of lower testosterone (T) to LH ratio and higher estradiol (E2) to T ratio in secretory infertile men compared to men with normal spermatogenesis, suggesting a steroidogenic dysfunction

Estradiol (E2) accelerates egg transport by a nongenomic action, requiring activation of estrogen receptor (ER) and successive cAMP and IP3production in the rat oviduct. Furthermore, E2increases IP3production in primary cultures of oviductal smooth m

Mating shuts down a 2-methoxyestradiol (2ME)-dependent, non-genomic activity that is responsible for accelerating egg transport in the rat oviduct. The aims of this work were to investigate the role of TGFβ1 in this 2ME-reduced activity and to deter

Vaginocervical stimulation (VCS) induces twice-daily prolactin (PRL) surges resulting in pseudopregnancy in the rat. Furthermore, activation of the extracellular signal-regulated kinase-1/2 (Erk-1/2) is involved in the effect of estradiol (E2) on the

In the rat oviduct, estradiol (E2) accelerates egg transport by a nongenomic action that requires previous conversion of E2to methoxyestrogens via catechol-O-methyltranferase (COMT) and activation of estrogen receptor (ER) with subsequent production

Summary Estradiol (E2) is normally metabolized to hydroxyestradiols and methoxyestradiols by CYP1A1, CYP1B1 and COMT. However, an altered production of these metabolites by a disturbed expression of these enzymes is associated with reproductive and n

Objective To determine the role of endothelin (EDN) signaling in the estradiol (E2) nongenomic and genomic mechanism that regulates egg transport in the oviduct.
