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.

Premature ovarian failure may be idiopathic or associated with several autoimmune and genetic disorders as X chromosome deletions. We report two cases of preamture ovarian failure associated with a deletion in the long arm of X chromosome. Both patients were nulligravidas presenting secondary amenorrhea and complaints of infertility, without family history of premature ovarian failure and reporting normal puberal development. Their karyotypes showed deletions of the distal long arm of all X chromosomes and were 46,X, del(Xq22) and 46,X, del(Xq13q28), respectively. After the diagnosis the patients decided to be submitted to an in vitro fertilization with egg donation.

BACKGROUND: patients with primary amenorrhea and gonadal dysgenesia have higher serum gonadotrophins and should be submitted to chromosome studies. Karyotype studies may be performed in gonadal tissue or peripheral blood however, it is not yet established if cases of primary amenorrhea without signs of virilization need additional investigation of gonadal karyotype. PURPOSE: to analize the gonadal karyotypes (ovaries) from patients with primary amenorrhea and compare them to their respective peripheral blood karyotypes. METHODS: clinical and karyotype data of 12 patients were retrospectively analyzed from January 1997 to December 2003. RESULTS: when the investigation was indicated for primary amenorrhea without signs of virilization, the gonadal and peripheral blood karyotypes were concordant in 8 cases (7 cases 46XX and 1 case 46XY). One patient with virilization signs was the only case of discordant karyotype. CONCLUSION: the present study suggests that the gonadal karyotype does not bring additional information to peripheral blood karyotype in patients with amenorrhea and no signs of virilization. Although all previous studies had a small number of patients, it seems advisable to investigate the gonadal karyotype in patients with signs of virilization. The cost-benefit analysis could allow cost and stress reduction for patients, family and institutions.
