[Follicular development patterns in infertile women with biphasic basal body temperature]

Seventy-one cases of infertile women with both normal menstrual cycle and biphasic BBT were studied with ultrasonography, laparoscopy, hormonal assay and endometrial histology. Signs for follicular development and ovulation were divided into four types: (1) normal ovulation in 12 cases; (2) ovulation of small follicle in 21 cases; (3) luteinized unruptured follicle in 15 cases; (4) small luteinized follicle in 23 cases. Mean serum progesterone levels in the luteal phase were within normal limits in all cases. Secretory endometrium accounted for 77.46%. Proliferative or hyperplastic endometrium accounted for 22.54%. The Authors conclude that the criteria of biphasic BBT, P levels and endometrial histology are not reliable enough for determine the cause of female infertility women. In this study the rate of salpingitis: and the rate of aberration of follicular development and chronic anovulation was 7.04%, 83.10% respectively. The latter played an important role in causing female infertility.
