A study of serum estradiol, progesterone, 17alpha-hydroxy-progesterone, testosterone, dihydrotestosterone, dehydroepiandrosterone (DHA), delta4-androstenedione (delta4-A), FSH, and LH was carried out in one of three sisters having polycystic ovarian disease for a period of 18 days before wedge resection, at the time of surgery, and for 24 days following wedge resection.
Since we have found the presence of high plasma BE concentrations in hereditary angioedema (HANE) during attacks as well as during symptom-free periods, we studied, by means of pelvic ultrasound scanning employed to determine the prevalence of PCO and of MFO, 13 women of reproductive age affected with HANE who were not on oral contraceptives.
The frequency of the human leukocyte antigen DQA1*0501 was 0.50 and 0.26 in subjects with polycystic ovary syndrome and control subjects, respectively (corrected for multiple comparisons, p = 0.067).
In addition, a new mutation was found in exon 20 of the insulin receptor gene in a patient with moderate insulin resistance associated with morbid obesity, acanthosis nigricans, and polycystic ovary syndrome.
This article surveys the congenital and late-onset forms of the common steroidogenic enzyme defects of the adrenal cortex--steroid 21-hydroxylase, steroid 11 beta-hydroxylase, and 3 beta-hydroxysteroid dehydrogenase deficiencies--in connection with the occurrence of polycystic ovarian disease.

There was no relationship between the presence of the variant LH and the clinical and hormonal parameter in the PCOS subjects; however, in the controls the presence of the variant LH was associated with a higher serum total testosterone (P = 0.046), oestradiol (P = 0.03) and SHBG (P = 0.002).
Our findings suggest that increased insulin receptor serine phosphorylation decreases its protein tyrosine kinase activity and is one mechanism for the post-binding defect in insulin action characteristic of PCOS.
Fourteen Caucasian families with 81 affected individuals have been assessed in which polycystic ovaries/male pattern baldness (PCO/MPB) segregates as an autosomal dominant phenotype (1).
In both types of follicles, follistatin and alpha-, beta a-, and beta b-subunit cytoplasmic staining were observed in granulosa cells, as were their corresponding messages, with the exception of the undetectable follistatin mRNA signal in the PCOS follicles.
A syndrome of female pseudohermaphrodism, hypergonadotropic hypogonadism, and multicystic ovaries associated with missense mutations in the gene encoding aromatase (P450arom).
We identified two mutations in the CYP19 gene responsible for aromatase deficiency in an 18-year-old 46,XX female with ambiguous external genitalia at birth, primary amenorrhea and sexual infantilism, and polycystic ovaries.
