Results of the present study showed that majority of females with hormonal imbalance had increase in gonadotrophins concentrations (serum LH and
FSH).
"We were able to find a potential compensatory mechanism whereby decreased sperm production relating to the type of underwear signals to the hypothalamus to increase secretion of gonadotropin, a hormone that acts on the testes and that is reflected by the increased levels of
FSH, to try to increase sperm production," Minguez-Alarcon said in a statement.
FSH is known to play an important role in male fertility and is associated with sperm production.
La
FSH tiene una vida media corta, por lo cual requiere realizar frecuentes aplicaciones para inducir superovulacion; dos aplicaciones diarias han resultado en una mayor respuesta superovulatoria que la obtenida con una sola aplicacion (6, 19, 26).
The under virilized males who had normal/raised basal LH,
FSH, testosterone but adequate response to hCG stimulation were diagnosed as cases of AIS.
To deepen a possible involvement of estrogen in the process, we have also compared the results with those obtained treating the animals with
FSH or with FSH-Clomiphene.
The pathogenesis of functioning gonadotropinomas is unknown; several theories have been postulated, among which some that stand out are greater production of intact and biologically active
FSH, hypersecretion of an abnormal form of
FSH that inhibits GnRH secretion at the level of the hypothalamus, further inhibiting secretion of
FSH and LH, inhibition of the union of the abnormal form of
FSH to
FSH receptors at the pituitary level, or loss of negative counter-regulation by estrogens towards gonadotrophins [5, 6].
Our unique
FSH technology ensures that any oil quality change is detected and reported in real time.
Overall, present findings indicated that
FSH supplementation was beneficial regarding nutritional aspects of broiler meat where FSH2 found suitable.
FSH and Estradiol:
FSH is secreted by the anterior pituitary and stimulates the growth of ovarian follicles (Image 1); these developing follicles secrete estrogen and inhibin, leading to feedback suppression of
FSH.
Serum LH and
FSH levels were determined at baseline and 30, 45, 60, and 90 min after injection of GnRH (100 [micro]g Relefact; Sanofi-Aventis, Frankfurt, Germany).
According to the Stages of Reproductive Ageing Workshop (STRAW) classification, there is a subgroup known as "Incipient Ovarian Failure" (IOF) or late reproductive ageing (Stage 3) characterised by elevated
FSH levels and regular menstrual cycle.
