Ovarian hyperstimulation syndrome The ovaries can swell, leak excess fluid into the body, and produce too many follicles, the small fluid sacs in which an egg develops. Fibroids should be treated if they are associated with abnormal uterine bleeding or if they are thought to be the cause of infertility. This is called the fulcrum effect.[22] Some surgeries (carpal tunnel for instance) generally turn out better for the patient when the area can be opened up, allowing the surgeon to see "the whole picture" surrounding physiology, to better address the issue at hand. Microsurgery in Pediatric Urology. (PDF, 13 MB) The National Foundation, 1977.

The Male-specific Region of the Human Y Chromsome is a Mosaic of Discrete Sequence Classes. (PDF, 754 KB) Nature, 2003.

When a man ejaculates and releases semen through the penis, the seminal fluid, or semen, helps transport the sperm toward the egg. Because of the action at the estrogen-receptor level within the hypothalamus, CC alleviates the negative feedback effect exerted by endogenous estrogens. [161, 162, 163] As a result, CC normalizes the GnRH release; therefore, the secretion of FSH and LH is capable of normalized follicular recruitment, selection, and development to reestablish the normal process of ovulation. [161, 164] The standard dose of CC is 50 mg PO qd for 5 days, starting on the menstrual cycle day 3-5 or after progestin-induced bleeding.
