we present 2 cases of likely rare event. in case 1, 3rd degree consanguineous marriage revealed inv(6) with same break points in parents who were found to be phenotypically normal. the same inv(6) being inherited in progeny but presented with low amh (anti mullerian hormone) and high level of fsh (follicular stimulating hormone) leading to polycystic ovarian syndrome/premature ovarian failure. ...

Background: Various hormone tests of the presence of spermatozoa on testicular sperm extraction (TESE) in azoospermic men have been investigated. Because of its clinical importance, we conducted this study to evaluate complete reproductive serum hormone levels in nonobstructive azoospermic (NOA) patients for determining markers which can predict the spermatogenesis. Materials and Methods: Seven...

Organophosphate pesticides are considered as endocrine disruptors that interfere with reproductive functions. The corpus luteum (CL) is a transient endocrine gland that produces progesterone, a crucial hormone for a successful beginning and maintenance of pregnancy. Steroidogenic acute regulatory protein (StAR) facilitates the rate-limiting transfer of cholesterol from the outer mitochondrial m...

Introduction: PCOS is an important reproductive and endocrine disorder in women in the reproductive age. Present reports indicate that Vitex agnus-castus acts through hypothalamus-pituitary axis. This study was carried out to evaluate the effects of Vitex fruit hydroalcoholic extract on the alteration of sex hormones in a PCOS animal model. Methods: Following 14 days of monitoring of estrous...

Energy restriction (ER) extends the life span and slows aging and age-related diseases in short-lived mammalian species. Although a wide variety of physiological systems have been studied using this paradigm, little is known regarding the effects of ER on skeletal health and reproductive aging. Studies in rhesus monkeys have reported that ER delays sexual and skeletal maturation in young male m...

Non-invasive endocrinology utilizes non-invasive biological samples (such as faeces, urine, hair, aquatic media, and saliva) for the quantification of hormones in wildlife. Urinary-based enzyme immunoassay (EIA) and radio-immunoassay have enabled the rapid quantification of reproductive and stress hormones in amphibians (Anura: Amphibia). With minimal disturbance, these methods can be used to a...

the aim of this study was to investigate the potential association between growth hormone gh/alui and growth hormone receptor ghr/alui polymorphisms with milk yield and reproductive performances in holstein dairy cows in iran. blood samples of 150 holstein cows were collected and their genomic dna was extracted using gene-fanavaran dna extracting kit. fragments of the 428 bp of exon 5 growth ho...
