  • GnRH
  • Low frequency gonadotropin-releasing hormone (GnRH) pulses increase FSH mRNA levels in the rat, but is not directly correlated with an increase in circulating FSH. (wikipedia.org)
  • As puberty approaches (usually between ages 10 and 14), the brain produces gonadotropin-releasing hormone (GnRH), which starts the changes toward sexual maturity. (rchsd.org)
  • GnRH signals the pituitary gland to release two puberty hormones into the bloodstream: FSH and luteinizing hormone (LH). (rchsd.org)
  • primordial
  • Based on bioinformatic and in situ hybridization analyses, we demonstrated the exclusive expression of R-spondin2 in oocytes of primary and more advanced follicles but not in oocytes of dormant primordial follicles. (labome.org)
  • Menopause
  • Follicle-stimulating hormone (FSH) may also be involved in decreasing bone mineral density during menopause, according to new research at the Medical College of Georgia in Augusta, GA. (medindia.net)
  • This hormone seems to sustain bone health, but it drops to an extremely low level during and after menopause. (medindia.net)
  • Hormone Replacement Therapy can be likened to an 'oasis in the desert' for women in the throes of menopause. (medindia.net)
  • mice
  • Following the promotion of early ovarian follicle development using R-spondin2, mice will be treated sequentially with eCG and hCG to stimulate the final phase of follicle development and to derive mature oocytes for fertilization and the derivation of pups. (labome.org)
  • treatment
  • Pre-treatment with R-spondin1-Fc led to the induction of early antral follicles capable of responding to sequential eCG and hCG treatment, leading to the generation of mature oocytes. (labome.org)
