PURPOSE: to evaluate the efficacy of in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI) in natural cycle (NC). METHODS: retrospective clinical trial that evaluated 70 treatment cycles in 60 couples that were submitted to IVF treatment with ICSI in NC performed in private clinic from 1999 until 2003. It was performed daily ultrasound monitorization or on alternate days, and urinary LH dosage when the follicle reached 16 mm of diameter. It was scheduled egg retrieval when the follicle reached 18 mm of diameter and 36 hours after hCG administration when the LH test was negative. Embryo transfer was performed 48 to 52 hours after ICSI. RESULTS: 70 ICSI cycles in 60 patients were performed and the indications of treatment included: male factor (47.1%), tubal factor (37.1%), associated factors (8.7%), unknown infertility (7.1%). Out of 70 cycles, 18 cycles were cancelled (25.7% of cancellation rate). Out of 52 patients that were submitted to ovarian punction to oocyte retrieval we found mature oocytes in 77% of the cases (40 cycles), in four cases we collected immature oocytes and in eight cases we could not found it. We had 70% of fertilization rate and only one fertilized oocyte did not achieve the cleavage stage. So, the transfers rate per punction and per mature oocyte was 52% and 67.5%, respectively. We had 11.4% of pregnancy rate per cycle, 15.4% per punction and 29.6% per embryo transfer. CONCLUSIONS: FIV/ICSI in NC seem to be a satisfactory option of treatment, with low costs and complications (multiple gestation and Ovarian Hyperstimulation Syndrome), mainly in poor responder patients and in poor populations.

PURPOSE: to evaluate the vascular blood flow of the central retinal arteries using dopplervelocimetry in the different phases of the ovulatory menstrual cycle. METHODS: we performed an observational, longitudinal and prospective study evaluating 34 healthy and ovulatory women. All women were submitted to Doppler scan of the eye to evaluate the vascular resistance of the central retinal arteries, either lying down or on a seated position, during four phases of the menstrual cycle. Confirmation of ovulation was performed by measuring serum progesterone during the luteal phase. We analyzed the pulsatility and resistance index and the maximum, minimum and mean velocity. RESULTS: mean age was 29.7 years. No differences were observed between the indexes obtained in both eyes, therefore a mean index was used for comparisons. As the comparison between the positions used for the exams showed a higher PI for the seated position, the analyses were performed separately. The pulsatility index in the lying position was different among the different phases of the menstrual cycle. The arterial resistance was significantly lower during the intermediate follicular and the periovulatory phases, as compared to the early follicular and luteal phases. When the comparison was performed with the patient in the seated position, no differences were observed. CONCLUSIONS: Our results demonstrate a reduction in the vascular resistance of the cerebral microcirculation and a posterior reversal, as shown by changes in the PI.

PURPOSE: to evaluate the association between women's menstrual experience and preferred changes in their menstrual cycles. METHODS: a cross-sectional study design was used. A total of 420 women were interviewed. Participants complied with the following criteria: age (18 to 20, 25 to 34 and 45 to 49 years); schooling (<8 years and >12 years); having menstruated during the three months previous to the study. Subjects were selected in the city of Campinas (SP), in nine private and seven public health services. For data collection, a questionnaire was prepared on the basis of the results of a previous pilot study that consisted of small groups. A data bank was prepared with the information registered in the questionnaires and the analysis was carried out with SAS, version 8.2. For the statistical analysis, the Pearson chi2 test and the Fisher exact test were used to evaluate the association between variables (p<0.05). RESULTS: most subjects preferred greater than once a month intervals between menstruations. There was an association of the typical menstrual intervals experienced by women (p=0.0248) and the degree of interference of menstruation with daily activities (p=0.048) with the preferred interval between menses. However, there was no association between preferred intervals by women and the following characteristics of pain: duration, intensity and use of medication. CONCLUSIONS: the results suggest that women would like intervals longer than one month or to never menstruate.

Purpose: to offer new data for the conflicting reports which present different prognosis for patients with breast carcinoma, according to the timing of surgery in relation to the menstrual cycle. Patients and Methods: in a retrospective study on 451 premenopausal women with breast cancer, aged between 26 and 52 years, 130 cases were selected and followed for 60 months, at least. Sixty-eight were operated during the follicular phase and 62 in the luteal period, whose findings regarding clinical stages, axillary involvement and estrogen and progesterone hormonal receptor concentrations of the neoplasms were also analyzed. Results: the follow-up of 130 patients showed that 64.4% had a disease-free survival after five years and 43% exceeded 10 years. Subdividing the cases into 2 subgroups, according to the timing of surgery, the survival rates were different, 58.8% at 5 and 36.7% at 10 years, when the operation occurred in the follicular phase, and 70.9% and 50%, at 5 and 10 years, respectively, during the luteal period. Conclusions: in this study, the patients operated in the luteal phase reached higher survival rates than the women operated during the follicular period. However, these values were lower than those displayed by the classic prognostic factors of axillary involvement and tumor size.

PURPOSE: to evaluate the luteal function in adolescents with regular menstrual cycles. METHODS: this prospective cohort study included 55 adolescents, aged 14-19 years, with menarche at 12.2 years. Ovulation was identified by ultrasound, starting on the second or fifth day of the cycle. The corpus luteum vascularization and the resistence index of the ovarian vessels were measured by Doppler on the tenth postovulatory day. Progesterone was measured by chemoluminescence on days 6, 9 and 12 of the luteal phase. The endometrial biopsy was performed 8 to 10 days after ovulation. The results were analyzed using the SPSS software and were considered significant when p<0.05. RESULTS: on average ovulation was on day 17. Progesterone levels were 11.4, 10.9 and 3.9 ng/mL on days 6, 9, and 12 after ovulation, respectively; the progesterone mean during the whole luteal phase was 10.3 ng/ml. Luteal vascularization was scarce in 34.6%, mild in 23.6% and exuberant in 41.8%. The resistance index was 0.441. On the tenth day post-ovulation the endometrium was normal in 85.5% and out-of-phase in 14.5%. There was no correlation between the ovulation day and endometrial dating (p=0.294), levels of progesterone and endometrial dating (p=0.454), progesterone and corpus luteum vascularization (p=0.994), or resistance index (p=0.237). There also was no association between endometrium development and degree of vascularization (p=0.611). CONCLUSION: abnormal luteal function in adolescents with regular menstrual cycles was found in 14.5%. Degree of vascularization, resistance index, and serum progesterone were not related to endometrium development.

Purpose: to analyze the symptoms of premenstrual syndrome (PMS), its duration, time of presentation and pathogenesis. Methods: a questionnaire was applied to 254 women aged 20 to 44 years, without gynecological or clinical conditions affecting their general state or physical well-being, excluding those with amenorreha for more than six months, hysterectomized or pregnant. Results: one hundred and ten women (43.3%) describing at least one intense symptom causing harm to their life, were considered as having PMS. Irritability was presented by 86.4%, tiredness by 70.9%, depression by 61.8%, headache by 61.8%, breast tenderness by 59.1% and abdominal pain by 54.5%. Almost all (94.5%) had more that one symptom, 89.1% presented psychological complaints, and 76.4% associated physical and psychological complaints. Most declared that duration of the symptoms was three to four days (32.4%) or five to seven days (31.4%). Conclusions: the clinical picture of PMS is generally composed of irritability and/or depression, associated with tiredness and headache or breast pain, there being association of physical and psychological symptoms, for 3 to 7 days, and it is difficult to attribute a single etiology to it at this stage of knowledge.
