title: [Prediction of Ovulation and timing of AIH].
abstract: The relation among ultrasonographic follicular diameter, serum estradiol (E2), luteinizing hormone (LH), cervical mucus changes, and basal body temperature (BBT) was studied. One hundred and eight cycles were examined in forty-two infertile patients. The last low day of the BBT curve was taken as day zero. In 83 of the 85 cycles, 158 of 163 times, follicles could be observed by ultrasonography. Follicular rupture was confirmed in 12 cycles. The mean diameter of the follicles measured the day before estimated ovulation was 24.00 +/- 3.10mm (mean +/- S.D.). Serum E2 levels were more than 400pg /ml from day -2 to day -1 and the peak serum LH levels occurred on day 0. The volume of cervical mucus (C.M.) was more than 100mm3 from day -2 to day +1. The volume was decreased in clomid stimulated cycles and the C.M. displayed a 3+ ferning 23/28 cycles on day 0. Among 5 pregnancies induced by homologous artificial insemination (AIH), three were done on day -2, one on day +1 and one on day +2. The best time to do AIH is when serum E2 is more than 400pg /ml, serum LH is more than 60m IU/ml, cervical mucus is 3+ ferning , and the follicular diameter is more than 20mm.
