Maternal virilization in pregnancy is associated, in most benigncases, with luteoma of pregnancy and hyperreactio luteinalis.Only a few reports relate this phenomenon to hyperthecosis orpolycystic ovarian syndrome (PCOS). A case of recurrent maternalvirilization during two consecutive pregnancies in a patientwith PCOS is presented. In both pregnancies, the deepening ofher voice, facial hirsutism and scalp hair loss began at theend of the first trimester and regressed 34 months post-partum.The patient underwent ovarian venous catheterization, and androgensecretion from both ovaries was found to be markedly high butsimilar, therefore ruling out an ovarian androgen-secretingtumour. Reviewing the English literature of similar cases, wefound reports of only seven cases of maternal virilization duringpregnancy associated with PCOS. Here, we present a case of recurrentmaternal virilization in pregnancy associated with PCOS. 相似文献

The triazole fungicides tebuconazole and epoxiconazole were investigated for reproductive toxic effects after exposure during gestation and lactation. Rats were dosed with epoxiconazole (15 or 50 mg/kg bw/day) or tebuconazole (50 or 100 mg/kg bw/day) during pregnancy from gestational day (GD) 7 and continued during lactation until postnatal day (PND) 16. Some dams were randomly chosen for cesarean section at GD 21 to evaluate effects on sexual differentiation in the fetuses. Other dams delivered normally, and the pups were examined (e.g., anogenital distance [AGD] and hormone levels) at birth, at PND 13 or PND 16, and semen quality was assessed in adults. Both tebuconazole and epoxiconazole affected reproductive development in the offspring after exposure in utero. Both compounds virilized the female offspring as shown by an increased AGD PND 0. Furthermore, tebuconazole had a feminizing effect on male offspring as shown by increased nipple retention. This effect was likely caused by the reduced testosterone levels seen in male fetuses. Tebuconazole increased the testicular concentrations of progesterone and 17alpha-hydroxyprogesterone in male fetuses, indicating a direct impact on the steroid synthesis pathway in the Leydig cells. The high dose of epoxiconazole had marked fetotoxic effects, while the lower dose caused increased birth weights. The increased birth weights may be explained by a marked increase in testosterone levels in dams during gestation. Common features for azole fungicides are that they increase gestational length, virilize female pups, and affect steroid hormone levels in fetuses and/or dams. These effects strongly indicate that one major underlying mechanism for the endocrine-disrupting effects of azole fungicides is disturbance of key enzymes like CYP17 involved in the synthesis of steroid hormones. 相似文献

A 52-year-old woman presented with symptoms of virilization, which had been ongoing for 5 months. At the age of 34 years, she had a large abdominal carcinoid tumour removed. Twelve years later, she presented with Cushing's syndrome due to ectopic adrenocorticotrophic hormone (ACTH) production by carcinoid metastases localized in the right parametrium, fornix posterior and right diaphragm. Debulking laparotomy was performed followed by remission of hypercortisolism. Relapse of hypercortisolism followed 3 years later, and a second debulking laparotomy was performed including resection of the right ovary. In the following year, relapses of hypercortisolism were observed until bilateral adrenalectomy was performed. Laboratory evaluation revealed elevated serum levels of testosterone (23.0 nmol/l), androstenedione and 17-hydroxyprogesterone, and a serum estradiol (E2) level in the premenopausal range. The computerized tomography (CT) of the abdomen showed a large pelvic mass on the left side of the uterus without a recognizable left ovary. Treatment with a GnRH agonist (goserelin, 3.6 mg s.c., monthly) was initiated, resulting in normalization of the androgen levels. One year later, obstruction of the right ureter occurred due to progression of the pelvic metastases, thus a third debulking laparotomy with resection of the pelvic metastases including the left ovary was performed. The microscopic examination of the removed pelvic mass showed malignant carcinoid tissue with focal remnants of atrophic ovarian tissue. Two years after surgery, serum androgen levels are undetectable. We hypothesize that the high levels of ACTH at the site of the left ovary have induced androgen hypersecretion by steroid-producing cells in the ovary of our patient. 相似文献

Topical testosterone has been used as a treatment for different vulvar conditions. It is usually well tolerated, although hirsutism and other signs of virilization have been described related to hormonal tests alteration. We report two female patients with vulvar diseases that developed hirsutism after treatment with topical testosterone. Because of its potential virilization, females under this treatment should be closely monitored. 相似文献

Congenital adrenal hyperplasia in females with viriiized genitalia: The problem of delayed diagnosis
Abstract Six girls with the non-salt-losing form of congenital adrenal hyperplasia are described. Diagnosis was delayed in five, the range of ages of diagnosis being 19 months-7 years. In the sixth, despite early diagnosis and medical treatment, surgery was delayed electively until she was 3 years old. The five in whom diagnosis was delayed were all viriiized with a markedly advanced bone age and reduced adult height prognosis. Diagnosis was delayed for a variety of reasons: misinterpretation of laboratory data (one), lack of availability of medical assistance (one), language problems (one), maternal inexperience (one), and failure of the doctor to recognize an obvious clinical abnormality (one).

Lactogenesis II is the onset of copious milk production (i.e., the milk "coming in"), which usually occurs between 30 to 40 hours postpartum. When lactogenesis II fails to occur or is delayed, it may be due to a number of underlying hormonal or non-hormonal conditions. Of the various hormonal etiologies, many can be identified with the aid of a few standard blood tests. Gestational ovarian theca lutein cysts may cause delayed lactogenesis II and are fairly easily detected by ordering testosterone levels. Although this condition can delay lactogenesis II for as long as 31 days, with proper management women affected by these cysts have established breastfeeding. Three of the four women reviewed in this article were eventually able to produce 100% of their infants' caloric requirements. 相似文献
