Abstract
It is now common practice to attempt ovarian hyperstimulation in vitro fertilization and embryo transfer (IVF-ET) to promote the development of multiple preovulatory follicles and to maximize the number of mature egg available. There are several drugs for hyperstimulation such as clomiphene citrate only, clomiphene citrate and human menopausal gonadotropin (HMG) and HMG only. Accumlated experience has shown that the hyperstimulation of the ovary in IVF-ET results in high pregnancy rate. But the hyperstimulation of the ovary in IVF-ET may cause the hyperandrogenism, so we must consider the adverse effect on pregnancy rate of the hyperandrogenism. Little is known about the functional significance of androgen for the follicular growth, however, the hyperandrogenism might interfere with oocyte maturation. The aim of the present investigation was to determine the serum profiles of estradiol, androstenedione and testosterone during the hyperstimulated menstrual cycles in IVF. The results were summarized as follows: 1. There was a gradual increase in the mean levels of serum estradiol, androstenedione, and testosterone approaching follicular maturation. 2. The mean serum estradiol levels in the hyperstimulated groups were significantly higher than that in the control group in late follicular phase and ovum retrieval (ovulation) day (p<0.01). 3. The mean serum androstenedione levels in the clomiphene citrate groups were significantly higher than that in the control group in late follicular phase (p<0.01). There was no statistically significant different in the mean serum androstenedione levels between the control group and the HMG group (p>0.05). 4. There was no statistically significant difference in the mean levels of testosterone among each group (p>0.05). 5. There was no statistically significant different in the mean levels of estradiol, androstenedione and testosterone between the fertilized patients and non-fertilized patients in clomiphene citrate and HMG group (p>0.05).
