Mammalian male fertility relies on complex inter- and intracellular signaling during spermatogenesis. Here we describe three alleles of the widely expressed A-kinase anchoring protein 9 (Akap9) gene, all of which cause gametogenic failure and infertility in the absence of marked somatic phenotypes. Akap9 disruption does not affect spindle nucleation or progression of prophase I of meiosis but d...

Background: Diminished ovarian reserve (DOR) predicts decreased response to stimulation. Low serum anti-Mullerian hormone (AMH) is associated with DOR. AMH a marker of and acts as predictor stimulation protocol. The up regulated by vitamin D via elements that bind the receptor. Vitamin supplementation has role in increasing AMH. objective was compare combined effect DHEA vs alone on Methods: Th...

We report a case of congenital adrenal hyperplasia due to 17 alpha-hydroxylase deficiency in a Chinese genotypic male patient. Despite the male genotype, normal female external genitalia were present and with the introduction of cyclical oestrogen therapy withdrawal bleeding occurred, confirming the presence of functional endometrial tissue. We believe this to be the first report of persistent ...

Persistent Mullerian Duct Syndrome (PMDS), a rare form of male pseudohermaphroditism. It is characterized by the persistence of Mullerian duct structures (uterus, fallopian tubes and upper two-thirds of vagina) in otherwise normally virilized males (Karyotype 46XY). The exact cause of PMDS is not known, however it is thought to result from the defect of the synthesis or release of Mullerian inh...

this study explored the effects of gnrh agonist (gnrha) immunity on expression of fshr mrna in pituitary and fshr protein in uteri, and also confirmed its efficacy on uterine development. 42 prepuberty and non cyclic ewes were assigned to 6 experimental groups (eg) during anestrus season. animals in eg-i, eg-ii and eg-iii were subcutaneously injected with 200, 300 and 400 μg alarelin antigens (...

background: the sertoli cells in the testis create unique and safe environment to protect seminiferous tubules from auto antigens and invading pathogens. these cells produce the survival factor of the blood-testis barrier and produce special materials such as androgen binding proteins and contribute to the coordinated action of spermatogenesis. given that the sertoli cells play an essential rol...

Gonadal differentiation is tightly regulated by the initial sex determining gene and the downstream sex-related genes in vertebrates. However, sex change in fish can alter the sexual fate from one sex to the other. Chemical-induced maleness in the protogynous orange-spotted grouper is transient, and a reversible sex change occurs after the chemical treatment is withdrawn. We used these characte...

Currently, in patients with systemic lupus erythematosus (SLE) increasing attention is paid to the ovarian reserve evaluation, which can serve as one of markers a favorable response therapy and pregnancy planning. For this purpose, anti-Mullerian hormone (AMH) considered most sensitive marker, that reflect continuous growth small follicles. The article presents data on relationship serum levels...
