Eight of these women were trying to conceive at the time of investigation and five succeeded.

The mean profiles of each of the four hormones were similar for the three groups studied. Statistical comparisons (using ‘t’ tests) between Groups II and III showed that FSH concentrations were significantly lower (P<0·01) in the late follicular phase (Days —7 to —3 before the LH peak) in Group III. Similarly, progesterone concentrations were significantly lower (P<0·05) during the early luteal phase (Days +3 to +7 after the LH peak) in Group III.The willing co-operation of all the women who took part in this study is gratefully acknowledged.
