[Natural latex (Hevea brasiliensis) mold for neovaginoplasty].

Purpose: to evaluate the use of natural latex mold (Hevea brasiliensis) as a modification of McIndoe and Bannister neovaginoplasty in patients presenting Mayer-Rokitansky-Küster-Hauser (MKRH) syndrome.

Methods: we retrospectively included nine patients presenting MKRH syndrome, who had been submitted to McIndoe and Bannister neovaginoplasty modified by the use of natural latex mold. Neovaginal epithelization and depth, coitus occurrence and satisfaction, and surgical complications were evaluated.

Lipid peroxidation and vitamin E in serum and follicular fluid of infertile women with peritoneal endometriosis submitted to controlled ovarian hyperstimulation: a pilot study.

Objective: To assess the level of lipid peroxidation (LP) and vitamin E in the follicular fluid and serum of infertile patients, with or without endometriosis, who were submitted to ovulation induction for assisted reproduction procedures.

Design: Prospective study.

Setting: Assisted conception unit, university hospital.

Positive correlation between serum and peritoneal fluid CA-125 levels in women with pelvic endometriosis.

Context And Objective: One of the diagnostic markers of endometriosis is CA-125, and elevated levels of this are caused by high concentrations in the ectopic endometrium. The objective of this study was to correlate CA-125 levels in serum and peritoneal fluid from women with and without pelvic endometriosis.

Design And Setting: This was a prospective, cross-sectional, controlled study of consecutive patients undergoing laparoscopy for infertility, pelvic pain or tubal ligation, during early follicular phase, at the university hospital of Faculdade de Medicina de Ribeirão Preto.

Reduced aromatase activity in granulosa cells of women with endometriosis undergoing assisted reproduction techniques.

The aim of the present study was to measure the in vitro aromatase activity in granulosa cells of women with endometriosis submitted to assisted reproduction techniques. A case-control study was conducted on eight patients with endometriosis and eight with other infertility causes submitted to in vitro fertilization or intracytoplasmic sperm injection. Granulosa cells were obtained from pre-ovulatory follicles during oocyte retrieval and cultured for 24 h in the presence or absence of testosterone (2 x 10(-6) and 2 x 10(-5) M), follicle-stimulating hormone (FSH) and insulin-like growth factor-I (IGF-I) (both at 50 ng/ml).

Growth hormone secretion and insulin-like growth factor-1 are related to hyperandrogenism in nonobese patients with polycystic ovary syndrome.

Women of normal weight with polycystic ovary syndrome (PCOS) and hyperinsulinemia presented high growth hormone (GH) levels in response to the l-dopa test, suggesting that the action of GH and insulin-like growth factor-1 (IGF-1) might be responsible for the elevation in LH and the consequent hyperandrogenic anovulation observed in normal weight women with PCOS. Insulin resistance and obesity are related to a reduction in GH secretion in obese women with PCOS.

Hormonal assessment of women submitted to tubal ligation.

Sixteen fertile women aged 30-35 years with regular menstruations were studied before and 6 months after tubal ligation (TL). The diagnosis of ovulation was based on clinical ultrasonographic and hormonal parameters [follicle-stimulating hormone (FSH), luteinizing hormone (LH), E2 and P4]. The menstrual pattern did not vary before and after surgery.

In vitro fertilization in patients with ovarian endometrioma.

Purpose: To assess the influence of ovarian endometrioma during IVF.

Methods: Patients were submitted to cystectomy by the laparoscopic route for exeresis of ovarian endometrioma. Group I (n = 28) consisted of patients without ovarian endometrioma and group II (n = 14) consisted of patients with recurrence of ovarian endometrioma during IVF.
