the most promising way to achieve pregnancy in a woman with Turner syndrome☆In vitro fertilization of Turner syndrome patients with an ovum provided by a related or anonymous donor results in pregnancy rates approaching 60%.
(Pregnancy can occur spontaneously in some patients with Turner syndrome, but the risk of spontaneous abortion, Down syndrome and Turner syndrome are all increased in such cases.) reproductiveobstetricsUWorld May 19, 2020, 5:28 PM HirotoShishido
mechanism of endometrial hyperplasia in postmenopausal obese womanSmall amounts of androgens continue to be produced in the ovaries and adrenal glands after menopause. In obese women, these androgens (eg, androstenedione) are readily converted to estrogens (eg, estrone) by the aromatase enzyme found in adipose tissue.
However, ovarian progesterone production remains low; therefore, the unopposed estrogen causes unregulated endom etrial proliferation and subsequent endometrial hyperplasia. reproductiveUWorld May 18, 2020, 12:22 AM HirotoShishido

FSH and inhibin in the patient with 1 testicle(Sertoli cells are present within the seminiferous tubules of the testes.)
In patients with 1 testicle, the mass of Sertoli cells is significantly reduced. Therefore, the circulating ☆levels of inhibin B are likely to be low in these patients. Low inhibin B levels will not provide adequate negative feedback on FSH secretion, thus ☆FSH levels will tend to be elevated in males who only have 1 testicle. reproductiveUWorld Feb 23, 2020, 11:16 PM HirotoShishido
