Then there are the actual studies performed on pregnant women and new mothers, which are ambiguous. Some show memory impairments, especially toward the end of pregnancy, when (psychologists theorize) the brain undergoes a process of neural reprogramming as it prepares to nurture the new baby.
At present it is unknown whether these effects are due to direct effects of growth hormone on hematopoietic cells or if they are caused by the induction of insulin-like growth factor-1 (IGF-1) synthesis.n support of the second possibility, we have induced apoptosis of both nonadherent bone marrow cells and a myeloid progenitor cell line by depriving these cells of CSFs. Preliminary results indicate that addition of IGF-1 to these cells reduces apoptotic cell death by 50%.
Testosterone Replacement Therapy. Testosterone is a major sex hormone produced in the testes of men. The pituitary gland is responsible for controlling the production of testosterone hormone. In the testes, luteinizing hormone binds to receptors on Leydig cells; this stimulates production and secretion of testosterone.Testosterone helps to develop the primary and secondary sexual characteristics in males.he pituitary gland is responsible for controlling the production of testosterone hormone.
