Recombinant (Human) Follicle Stimulating Hormone - Genetically engineered follicle stimulating hormone as opposed to FSH extracted from the urine of post menopausal women. It is synthesized in vitro by cells into which genes encoding for FSH subunits have been inserted. Brand names are Gonal-F and Follistim. Recurrent Pregnancy Loss , Recurrent Miscarriage, Recurrent Spontaneous Abortion (RSA) - Repeated miscarriages. Testing can be done to try to determine the cause of such losses. If an underlying condition is found, the woman may need to be treated for the problem before a pregnancy can be carried to term. Reproductive Endocrinologist - A medical specialty combining obstetrics and gynecology with endocrinology to treat reproductive disorders. Reproductive Surgeon - An ob-gyn or urologist who specializes in the surgical correction of anatomical disorders that affect reproductive function. Repronex - A medication used to replace the pituitary hormones LH and FSH. Similar to Humegon and Pergonal. May be used to induce ovulation in women who do not respond to clomiphene citrate. Most frequently used with women who do not normally produce estrogen because of a pituitary gland or hypothalamic malfunction. May also be used with men to stimulate sperm production. R-FSH, R-hFSH - See Recombinant (Human) Follicle Stimulating Hormone. Resistant Ovary - An ovary that cannot respond to the follicle-stimulating message sent by FSH. Primitive germ cells will be present in the ovary; however, they will not respond to FSH stimulation. Retrograde Ejaculation - A male fertility problem that allows the sperm to travel into the bladder instead of out the opening of the penis due to a failure in the sphincter muscle at the base of the bladder. Retroverted Uterus - Uterus that is tilted back toward the rectum. Reversal - Term used in infertility for undoing a sterilization procedure such as a tubal ligation or vasectomy.
