RESUMO
The nature and incidence of normal and abnormal spontaneous ovarian cycles, identified with ultrasound and endocrine tracking, were examined in 45 regularly cycling infertile women with no definitive cause and 15 women who were apparently normal and were receiving donor insemination because of clearly infertile partners. In 136 cycles, four apparently distinct abnormal patterns were detected. The total incidence in the infertile group was 58% compared with 23% in the donor insemination group (P less than 0.005). Twelve of 26 subjects who had at least three cycles tracked showed two different abnormalities, and 1 subject had three different abnormalities in five abnormal cycles. These results suggest that abnormal cycles are a significant factor in unexplained infertility and that diagnosis and treatment cannot be based on the study of a single cycle.

Twenty conception cycles were tracked with ultrasound ovarian scanning from the midfollicular to midluteal phase, and simultaneous hormone profiles were obtained in 18 of the cycles. Twelve cycles were spontaneous and 8 were induced with a variety of regimens. Two of the spontaneous cycles did not have endocrine data, and in one other no follicular growth was observed, despite repeated scanning. The induced cycles did not differ significantly from the spontaneous ones in any respect except the number of follicles and the consequent estradiol (E2) levels. E2 levels per unit total follicular surface area, however, were similar in both groups and remained relatively constant throughout the late follicular phase.

The intraobserver and interobserver variation of ultrasound measurement of Graafian follicles was assessed. Fourteen follicles from 10 to 30 mm in diameter were each measured three times in three orthogonal planes by three observers. The intraobserver standard deviation (SD) was 0.6 mm and interobserver SD, 1.2 mm, irrespective of follicle diameter. The pooled SD for both variables was 1.2 mm, giving 95% confidence limits of +/- 2.4 mm for any measurement.

Immunoglobulin levels were measured by agar gel single radial immunodiffusion in the serum and cervical mucus of 50 tailed copper IUD users, 20 combined oral contraceptive users and 20 women not using contraception (controls). IgG, IgA and IgM levels were significantly higher in the copper IUD users compared to the other two groups. It is not known whether this was related to the small numbers of bacteria found in the uterine cavity of tailed IUD users or to the foreign body reaction of the device.
