The prediction of ovulation: a comparison of the basal body temperature graph, cervical mucus score, and real-time pelvic ultrasonography.

Ninety-five menstrual cycles were studied in 20 women undergoing donor artificial insemination (AID). In 49 cycles basal body temperature (BBT) changes were charted daily and both daily cervical mucus scoring (modified Insler score) and daily realtime ultrasonography (USS) were performed from day 11 to ovulation. AID was performed only on the day of follicular rupture. A control group, not subjected to USS, were inseminated two to three times per cycle over 46 cycles in the periovulatory period. The Insler score was found to be a reliable indicator of follicular development and rupture. The BBT was found to be less reliable than the Insler score or USS. While USS may be used to confirm follicular development, the Insler score is reliable and less costly.

Involving the male partner for interpreting the basal body temperature graph.

OBJECTIVE: To determine if the male cohabiting partner of a woman may serve as a control for exogenous influences on basal body temperature (BBT). METHODS: Twelve couples from the Atlanta area were enrolled for a total of 41 couple-cycles. Couples recorded their oral temperatures daily and used urinary test kits for luteinizing hormone to estimate the day of ovulation. The covariability between the pre-ovulatory temperature of the women and their partners was assessed. The gaps in the couples' temperatures (female temperature minus male temperature) were compared in the pre- and postovulatory phases. RESULTS: Considerable covariability was found between temperatures of partners in the pre-ovulatory phase (covariance parameter = 0.49; P <.001). The pre- and postovulatory temperature gaps for all couples were significantly different in size (P <.001). For all couple-cycles, the size of the mean postovulatory temperature gap was at least 0.3-degree Fahrenheit greater than the mean pre-ovulatory temperature gap. CONCLUSION: Recording the BBT of women's partners may improve interpretation and accuracy of the BBT method. An increase in the size of a couple's temperature gap accompanies the transition from the pre- to the postovulatory phase. By this method, a given couple could determine their unique temperature gap indicating this transition.

Cervical mucus and prediction of the time of ovulation.

12 normal ovulatory women were studied during 17 menstrual cycles. The first day on which the women had increasing quantities of 0.1 ml or more clear cervical mucus (IQCCM) was closely related to the time of ovulation as monitored by basal body temperature and radioimmunoassay of serum-luteinizing hormone, follicle-stimulating hormone, estradiol, and progesterone. The results show that the time of ovulation can be predicted clinically without specialized tests by observing the day of onset of IQCCM.

Daily fecundability: first results from a new data base.

This multicenter study has produced a database of 7017 menstrual cycles contributed by 881 women. It provides improved knowledge on length and location of the "fertile window" (identified as of up to 12 days duration) and the patterns and level of daily conception probability. The day of ovulation was identified in each cycle from records of basal body temperature and mucus symptoms. By referencing days of intercourse to the surrogate ovulation markers, estimates of daily fecundability were computed either directly or by the Scwartz model, both for single and multiple acts of intercourse in the fertile window. The relationship between coital pattern and fecundability has been explored. Univariate analysis underlines the significant link with fecundability only of the woman's reproductive history.

A biphasic basal body temperature record during pregnancy.

A case of biphasic temperature record is reported during the course of an ectopic pregnancy. Possible implications of this phenomenon may improve our understanding of the role of ovum transmigration and the endocrinological interaction of pregnancy with hormonal control of ovulation.

Natural family planning indicators of ovulation.

Indirect evidence of the occurrence of ovulation, which is generally accepted, is an increase in plasma or serum progesterone. Pelvic ultrasonography can estimate the probable time of ovulation within 12 h. There is a close association between the rise in progesterone, luteinizing hormone (LH) and oestrogen peaks and ovulation. A WHO study reported that ovulation occurred at a median time of 8 h after the rise in plasma progesterone, 15 h after the LH peak and 24 h after the oestrogen peak. The basal body temperature (BBT) method is the most effective in determining the premenstrual infertile period, but it is unreliable for an accurate determination of ovulation and the postmenstrual infertile period. Nor is BBT an effective method of predicting ovulation during postpartum lactational amenorrhoea. Therefore, BBT is usually used as a secondary indicator of ovulation and is combined with more reliable indicators. Observed changes in cervical mucus patterns can be used to define the probable fertile period, although this method produces a wide range of days. The peak mucus symptom is closely correlated with ovulation. Mucus symptoms can be used as a guide for the timing of blood or urine samples for estimation of LH, oestrogen and progesterone or their metabolites. Symptothermal methods incorporate other symptoms such as cervical changes, intermenstrual pain, breast tenderness and backaches, but these are secondary signs of ovulation and are recommended to be used in conjunction with mucus and BBT.
