CONTEXT Idiopathic hypogonadotropic hypogonadism (IHH) with normal smell (normosmic IHH) or anosmia (Kallmann syndrome) is associated with defects in the production or action of GnRH. Accordingly, most IHH patients respond to physiological pulsatile GnRH replacement by normalizing serum LH, FSH, and testosterone (T) levels and achieving gametogenesis; some patients, however, show atypical respo...
The regulation of steroidogenesis of human fetal, rhesus monkey fetal and newborn testes was studied in vitro and in vivo. Human fetal testes (first half of gestation) bound specifically radioiodinated human chorionic gonadotropin (hCG) and responded with an increase of testosterone (T) production to physiologic levels (5 to 50 ng/mi) of hCG in incubations. Furthermore, placental effusate stimu...
BACKGROUND & OBJECTIVES Hyperprolactinaemia affects testicular functions by influencing hypothalamo-pituitary-testicular (HPT) axis at various levels. Available literature on the level of defect, time course of improvement of gonadal functions and its relation with decline in prolactin levels is scanty. We carried out this study to evaluate the HPT axis in patients with macroprolactinomas, befo...
Aim: A testicular germ cell tumour is not observed widely, but its incidence and mortality rates have increased in recent years. One of the most common forms this seminoma. Germ neoplasia situ (GCNIS) precursor The apelin/APJ axis many cancers a pathway that plays an active role angiogenesis, lymphangiogenesis, growth, migration. This study investigated cellular distributions apelin APJ protein...
Background and purpose: Studies have indicated that phytoestrogens in soybean can influence the reproductive system. The aim of this study was to investigate the effect of hydroalcoholic extract of soybean on testicular tissue and pituitary-gonad axis in male rat. Materials and methods: Forty adult male Wistar rats were randomly allocated into five groups including control, sham, and three...
To study how hydrogen-rich saline (HS) promotes the recovery of testicular biological function in a hemi-sectioned spinal cord injury (hSCI) rat model, a right hemisection was performed at the T11-T12 of the spinal cord in Wistar rats. Animals were divided into four groups: normal group; vehicle group: sham-operated rats administered saline; hSCI group: subjected to hSCI and administered saline...
