We report on 12- and 14-year old sisters with a 46, XY chromosome constitution, normal female external genitalia, and absence of gonadal tissue. Except for omphalocele, right renal agenesis and malrotation of the colon in the elder sister, the internal organs were normal. Both were mentally retarded, of short stature, and had extremely retarded bone age. In addition, they had an almost identical pattern of minor anomalies: peculiar face, hypodontia, short neck, inverted nipples, thoracolumbar scoliosis, "dysplastic" hips, partial clino-/syndactyly of toes. The occurrence of a basically similar set of malformations in two sisters and the first cousin consanguinity of the parents suggests autosomal recessive inheritance. The conserved region of the SRY gene ([high mobility group] HMG box) was sequenced in the elder sib and was normal. No consistent malformations are observed at present in agonadal patients. This supports the idea that several autosomal genes have the potential of influencing the sequence of events of sex determination.

The LH secretory patterns and ovarian endocrine responses have been determined during pulsatile gonadotropin-releasing hormone (GnRH) administration for induction of ovulation in patients with hypothalamic amenorrhea (HA). However, until now these endocrine dynamics during GnRH therapy have not been thoroughly investigated in patients with polycystic ovarian disease (PCOD). Seven patients with HA and 4 patients with PCOD have therefore been studied to determine changes in LH pulsatile activity and in serum sex steroid levels in response to chronic intermittent GnRH stimulation. GnRH was administered intravenously (5-10 micrograms/90 minutes) by means of a portable infusion pump. Blood samples were obtained at 15-minute intervals for 4 hours on the day before the start of GnRH stimulation (control day) and on treatment days 5, 10 and 15. LH was determined in all samples and FSH, serum androgens and estrogens were measured in baseline samples by RIA. While 8 (62%) ovulations and 5 conceptions were observed in 13 treatment cycles in patients with HA, no ovulations were achieved during 9 treatment cycles in patients with PCOD. On the control day significantly (p less than 0.05) higher basal LH and testosterone (T) levels and significantly (p less than 0.05) lower FSH levels were found in the PCOD patients. The LH pulsatile profiles of the PCOD patients showed significantly (p less than 0.05) higher pulse amplitudes and areas under the curve (integrated responses). Pulsatile GnRH administration induced a significant (p less than 0.05) increase in LH pulse amplitudes in both HA and PCOD patients, and also increased (p less than 0.05) the integrated responses in patients with HA. During the GnRH stimulation, the LH interpulse intervals of both HA and PCOD patients were found to be similar to the frequency in which exogenous GnRH was administered. FSH levels rose continuously (p less than 0.001) during stimulation in patients with HA, but remained unchanged in patients with PCOD. In HA patients, T, androstenedione (AD) and estrone (E1) did not change during the GnRH treatment, but estradiol (E2) rose so that the ratios of aromatized estrogens to non-aromatized androgens (E1/AD, E2/T) increased. In contrast, T and AD increased significantly (p less than 0.05 or less) and E2 remained unchanged during stimulations in PCOD patients, which resulted in decreasing ratios of estrogens to androgens. These observations confirm that pulsatile GnRH administration can successfully induce ovulation in patients with HA by restoring the ovarian physiology. The data also demonstrate that pulsatile GnRH administration can influence the LH secretory patterns in PCOD patients.(ABSTRACT TRUNCATED AT 400 WORDS)

The bacterial colonizing of the intrauterine device (IUD) and its tail were studied in 152 IUDs obtained from 70 symptomless IUD wearers, 13 women with dysfunctional bleeding, 23 women with pelvic inflammatory disease, 31 women in whom the tail of an IUD was no longer visible and 17 women who were pregnant with an IUD in situ. The IUDs were either removed by the transcervical route or through a fundal incision in the uterus after hysterectomy. Most IUD were heavily contaminated by bacteria, especially Staphylococcus epidermidis, Enterococci and anaerobic Lactobacilli. The number of colonies was higher in women with dysfunctional bleeding and pelvic inflammatory disease than in others with a predominance of pathogenic bacteria, namely beta-hemolytic Streptococci, Staphylococcus aureus and Escherichia coli. Almost half of the IUDs without a tail protruding through the cervix were sterile. With pregnancy in the presence of an IUD, 71% of devices grew bacteria which were mainly anaerobic.
