Global ablation of INSL3 hormone or its receptor RXFP2 in male mice results in cryptorchidism and infertility. Using novel LacZ knock-in Rxfp2 allele we demonstrated a strong expression of this gene in postmeiotic germ cells. RXFP2 was expressed in embryonic and neonatal gubernaculum. No RXFP2 expression was detected in cremaster muscles in adult mice. We produced a floxed allele of Rxfp2 and t...
A 5-day Hershberger assay, a 20-day pubertal male assay, a one-month oral administration study and a reproductive toxicity study were carried out using an antiandrogenic chemical, flutamide (FL). The effects of FL were as follows: weight decrease in male reproductive organs such as the prostate and seminal vesicles were observed at ≥0.6 mg/kg/day as the most sensitive parameter in the Hershberg...
In mammals, puberty is a process of acquiring reproductive competence, triggering by activation of hypothalamic kisspeptin (KiSS)-gonadotropin releasing hormone (GnRH) neuronal circuit. During peripubertal period, not only the external genitalia but the internal reproductive organs have to be matured in response to the hormonal signals from hypothalamic-pituitary-gonadal (H-P-G) axis. In the pr...
Background and Objective: Evaluation of the importance and the effects of plant derived drugs on fertility of laboratory animals have long been recognized. In this research the effects of administration of aqueous extract of Boswellia thurifera on fertility indices, body weight and reproductive organs weight was evaluated in male rats. Materials and Methods: Eighteen rats were randomly divided ...
