Factors Related to Coital Frequency of Women in Their Thirties.

This cross-sectional study aimed to identify factors related to coital frequency (CF) among 254 women in their 30s using a semistructured interview to collect sociodemographic, anthropometric, reproductive, clinical, and relationship data. CF was characterized as (a) never, (b) rarely (≤1 times/month), (c) occasionally (≤1 times /week), (d) regularly (2-3 times/week), or (e) frequently (>3 times/week). The mean age was 34.

Sexual function of women practicing sex in nonconventional settings.

The quality of sexual intercourse in the context of conjugal visits by women to their jailed partners is unknown. This study aimed to assess the quality of the sex lives and psychological conditions of women attending conjugal visits with their jailed inmate partners. This controlled study involved 124 women between the ages of 18 to 40 years who engaged in sexual relations with their inmate partners (conjugal visit group) or with their partners at home (control group).

[Metabolic profile in women of different body mass indices with polycystic ovary syndrome].

Purpose: To characterize and compare clinical, anthropometric and biochemical-metabolic variables in patients with polycystic ovary syndrome (PCOS), stratified according to body mass index (BMI).

Methods: A cross-sectional study conducted on 78 women aged 18 to 45 years with a clinical diagnosis of PCOS by the Rotterdam criteria. Patients were stratified according to BMI.

[Clinical use for anti-mullerian hormone in gynecology].

Anti-mullerian hormone (AMH) is a glycoprotein produced by granulosa cells of primary, pre-antral and small antral ovarian follicles and its clinical applicability has been recently demonstrated by several studies. Prediction of the response to ovarian stimulation for in vitro fertilization corresponds to the most frequent utilization of AMH in clinical practice, being routinely assessed in many services to identify subgroups of women susceptible to a poor response or to Ovarian Hyperstimulation Syndrome. There are great perspectives that AMH may be applicable to the individual determination of risk for iatrogenic gonadal injury in women with neoplasms who will be submitted to chemotherapy.

[Serum anti-Müllerian hormone to predict ovarian response in assisted reproduction cycles].

Purpose: To compare serum anti-Mullerian hormone (AMH) levels on the seventh day of ovarian stimulation between normal and poor responders.

Methods: Nineteen women aged ≥35, presenting with regular menses, submitted to ovarian stimulation for assisted reproduction were included. Women with endometriosis, polycystic ovarian syndrome or those who were previously submitted to ovarian surgery were excluded.

[Serum markers of oxidative stress in infertile women with endometriosis].

Purpose: to compare serum markers of oxidative stress between infertile patients with and without endometriosis and to assess the association of these markers with disease staging.

Methods: this was a prospective study conducted on 112 consecutive infertile, non-obese patients younger than 39 years, divided into two groups: Endometriosis (n=48, 26 with minimal and mild endometriosis - Stage I/II, and 22 with moderate and severe endometriosis - Stage III/IV) and Control (n=64, with tubal and/or male factor infertility). Blood samples were collected during the early follicular phase of the menstrual cycle for the analysis of serum malondialdehyde, glutathione and total hydroxyperoxide levels by spectrophotometry and of vitamin E by high performance liquid chromatography.

Oocyte diameter as a predictor of fertilization and embryo quality in assisted reproduction cycles.

Objective: To assess the impact of the mean oocyte diameter (MOD) on occurrence of fertilization and embryo quality in assisted reproduction cycles.

Design: Prospective observational study.

Setting: Sector of Human Reproduction of the University Hospital, Faculty of Medicine of Ribeirão Preto, University of São Paulo (HCFMRP-USP).

[Meiotic abnormalities of oocytes from patients with endometriosis submitted to ovarian stimulation].

Purpose: to evaluate the meiotic spindle and the chromosome distribution of in vitro mature oocytes from stimulated cycles of infertile women with endometriosis, and with male and/or tubal infertility factors (Control Group), comparing the rates of in vitro maturation (IVM) between the two groups evaluated.

Methods: fourteen patients with endometriosis and eight with male and/or tubal infertility factors, submitted to ovarian stimulation for intracytoplasmatic sperm injection have been prospectively and consecutively selected, and formed a Study and Control Group, respectively. Immature oocytes (46 and 22, respectively, from the Endometriosis and Control Groups) were submitted to IVM.

[Evaluation of meiotic abnormalities of oocytes from polycystic ovary syndrome patients submitted to ovarian stimulation].

Purpose: to evaluate the meiotic spindle and the chromosome distribution of in vitro matured oocytes obtained from stimulated cycles of infertile women with polycystic ovary syndrome (PCOS) and with male factor and/or tubal infertility (Control Group) and compare in vitro maturation (IVM) rates between the groups analyzed.

Methods: five infertile patients with PCOS and eight controls, submitted to stimulated cycles for intracytoplasmic sperm injection, were selected prospectively and consecutively, and respectively assigned to the study group and the Control Group. Immature oocytes (21 and 29, respectively, from PCOS and Control Group) were submitted to IVM.

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.
