Safe and effective induction of ovulation with use of PREGNYL requires monitoring of ovarian response with serum estradiol and transvaginal ultrasound on a regular basis.

The combination of both pelvic ultrasound and serum estradiol measurement are useful for monitoring the development of follicles, for timing of the ovulatory trigger, as well as for detecting ovarian enlargement and minimizing the risk of the Ovarian Hyperstimulation Syndrome and multiple gestation.

This may be estimated by pelvic ultrasound alone or in combination with measurement of serum estradiol levels.

Confirm the number of growing follicles using ultrasonography because serum estrogens do not give an indication of the size or number of follicles.
