A study was made of the endometria of 16 patients with gonadal dysgenesis who had been give cyclic replacement treatment with conjugated estrogens for 2 to 10 years, and of 9 other patients who had received medroxyprogesterone in addition to the conjugated estrogens for 2 to 5 years. Seven of the
Four hypergonadotrophic women between 25 and 37 years of age with gonadal dysgenesis were treated sequentially with estrogens and a progestin. The hormonal environment induced by this therapy was similar to that of ovulating women, as demonstrated by serum levels of estradiol, endometrial histology
Eleven patients with Turner syndrome and 6 with pure gonadal dysgenesis were examined. Diagnosis was made on the base of clinical and cytogenetic examination. All patients had primary amenorrhea and underdevelopment of primary, secondary and tertiary sexual features. Hormonal estimations revealed
BACKGROUND
The rare association of mixed gonadal dysgenesis and non classical congenital hyperplasia by 21-hydroxylase deficiency poses the problem of their respective responsibility in the development of sexual ambiguity.
METHODS
In a newborn with ambiguous genitalia, blood 17-OH progesterone was
Cyclic replacement therapy using estrogen and progesterone was instituted in 28 patients with gonadal dysgenesis and 13 patients with hypopituitarism. When estriol was given at a dose of 2 mg per day, 10 patients (9 gonadal dysgenesis and 1 hypopituitarism) developed hyperreninemia and 3 of the 10
In 4 cases of gonadal dysgenesis the clinical, hormonal, cytogenetic, and histological findings were correlated. There were 2 patients with 46,XY karyotype, one patient with 45,X Turner's syndrome and one patient with a 46,XX chromosome complement. All patients had streak gonads with ovarian stroma.
BACKGROUND
Gender identity is influenced by genetic and hormonal factors and also by the sex of rearing.
METHODS
A child was born with ambiguous genitalia. Male sex assignment was made. Hypospadias and left inguinal hernia were present. The hernial sac contained an ovarian tissue. Plasma
Embryo transfer was performed in three mares with gonadal dysgenesis. Karyotypes of the mares were as follows: Mare 1, 63,XX, 64,XX, 65,XX; Mare 2, 63,X; and Mare 3, 65,XXX. The mares were administered progesterone in oil, 300 mg intramuscularly daily, starting 1 or 2 days after donor mare
To determine the pathogenesis of carbohydrate intolerance associated with gonadal dysgenesis, plasma glucose, insulin, glucagon, and growth hormone responses to oral glucose and intravenous tolbutamide, arginine and insulin were evaluated in 21 nonobese patients, 7-19 years old. Glucose intolerance
Cyclical hypothalamic function was investigated in three patients with an XY karyotype and female external genitalia; in one of them we diagnosed gonadal agenesis, and in the other two testicular feminization. We studied the effect of estradiol and progesterone on gonadotropin release. The patient
About 120 cases of XY gonadal dysgenesis have been reported on. We treated such a patient with bilateral gonadectomy. The gonadal tissue's capacity to respond to hormonal trophic stimulation was assessed. When the gonads were examined ultrastructurally, structures with the morphologic
The sexual development and behavior of 37 women suffering from the gonadal dysgenesis syndrome were investigated. It was found that their sexual development was significantly retarded compared with a control group of 50 fertile patients of the same age. This retardation was greater in a subgroup of
BACKGROUND
46,XY, or Swyer syndrome, is a complete gonadal dysgenesis. Patients usually presents with primary amenorrhea with underdeveloped secondary sex characteristics. Phenotypes of these patients are female. In this report, a Swyer syndrome case is reported with novel clinical features that are
To determine the influence of estrogenic steroids on serum FSH bioactivity (B) and immunoreactivity (I) and the FSH isoform distribution profiles, we studied normal women during ovulatory menstrual cycles and a patient with gonadal dysgenesis treated with diethylstilbestrol (DES). Four women with
A 16-year-old person, reared as female presented with complaints of genital ambiguity and primary amenorrhoea along with lack of secondary sexual characters, but without short stature and Turner's stigmata. She was taking steroids after being misdiagnosed as congenital adrenal hyperplasia (CAH).
