OBJECTIVE
In girls with congenital adrenal hyperplasia the degree to which excess androgen exposure leads to the development of prostatic tissue is largely uncharacterized, except in rare case reports of prostatic growth and adenocarcinoma. Such growth yields concern for future malignant
The effect of ACTH administration for 1-5 days on the morphology and steroidogenic capability of sheep adrenal tissue has been examined. During this period of treatment there was a gradual decline in the in vitro conversion of 3H-labelled precursors to products of solely zona glomerulosa origin
The effects of the s.c. administration of a depot formulation of the luteinizing hormone-releasing hormone (LHRH) analogue Zoladex were studied in normal male rats, alone and in combination with three drugs with "antiandrogenic" action (ketoconazole, cyproterone acetate, and RU 23908) on prostatic
The major hazard of postmenopausal cyclic estrogen therapy is endometrial hyperstimulation. The incidence of hyperplasia is dose dependent; the incidence of carcinoma is both dose and duration dependent. The risk of carcinoma is small. Invasive procedures such as endometrial biopsy to detect those
The authors report a case of a dysgenetic male pseudohermaphroditism with a 45,X/46,XY karyotype in a mosaic form, which was diagnosed in an infant. The one-week-old infant was evaluated because of proximal hypospadias and retention of the right testis. The results of hormonal tests were the
Discharge of municipal wastewater promotes the entry of diverse oestrogenic compounds into the water bodies. This complex mixture of substances interferes in the steroidogenic pathway, being able to promote severe reproductive impairment in freshwater fish populations. The purpose of the present
Adrenocortical disease (ACD) is a common problem in surgically sterilized, middle-aged to old ferrets (Mustela putorius furo). The adrenal tissues of these ferrets develop hyperplasia, adenomas, or adenocarcinomas, which produce steroid hormones including estradiol, 17-hydroxyprogesterone, and
We have followed nine adult patients with congenital adrenal hyperplasia (CAH) for between 7-77 months on dexamethasone (DXM) 0.5 mg mane and 0.25 mg nocte, reducing to 0.5 mg mane. Twenty-four hour profiles of ACTH, 17-hydroxyprogesterone (17OHP), and androstenedione were performed; the areas under
Slices of each of the six antral follicles at different stages of atresia isolated from ovaries of six patients with or without pretreatment with HCG before laparotomy, were incubated with [1-14C] acetate. Incorporation into progestins, androgens and oestrogens was assessed by the reverse dilution
BACKGROUND
Classical congenital adrenal hyperplasia (CAH), a genetic disorder characterized by 21-hydroxylase deficiency, impairs male fertility, if insufficiently treated.
METHODS
A 30-year-old male was referred to our clinic for endocrine and fertility assessment after undergoing unilateral
This study was undertaken to determine whether maintenance of spermatogenesis in hypophysectomized rats by pregnenolone and other C21 steroids may be due to in vivo conversion of these compounds to androgens. Hypophysectomized rats were treated sc with 2 mg of pregnenolone, 17-hydroxypregnenolone,
Clinical status, skin biopsy specimens, and endocrine function were evaluated in normal-coated Pomeranians (n = 12) and Pomeranians affected with growth hormone (GH)-responsive dermatosis (n = 7), then were compared with values in mixed-breed dog controls (n = 19). All Pomeranians were clinically
Although the pathogenesis of polycystic ovarian syndrome (PCOS) is still controversial, a series of investigations has demonstrated an array of neuroendocrine abnormalities as a major component of the syndrome. From a neuroendocrine perspective, patients with PCOS exhibit an accelerated frequency
