Role of Low-Dose Human Chorionic Gonadotropin Following Clomiphene Citrate in Folliculogenesis and Ovulation in Infer-tile Women

Abstract

Background:Ovulation disorders, usually presents as menstrual disturbance, are the cause of infertility in around 25% of couples who have difficulty to conceive. The drug most commonly prescribed for the induction of ovulation is clomiphene citrate (CC). If the patient does not ovulate after the use of CC, the choice was to add gonadotropins. Gonadotropin therapy is very expensive with significant risks of high order multiple gestations and ovarian hyperstimulation syndrome. Human chorionic gonadotropin hCG can function as a surrogate for LH and oc-cupies LH receptors for more than 24 hours allowing prolonged stimulation also it has longer half-life and greater affinity for the LH receptor. Objective: The purpose of this study was to compare the effectiveness of low-dose human chorionic gonadotropin (hCG) in the late follicular phase to induce ovulation in clomifene citrate resistant patients who had previously failed to ovulate on clomiphene citrate (CC) alone. Subjects,Materials and Methods: A total of 71 patients who attend infertility clinic in the High Institute of Infertility Diagnosis and Assisted Reproductive Technologies, Al-Nahrain University, where prospectively randomly assigned into two groups. hCG Group received 100 mg dose of CC from day 5 of men-strual cycle for 5 days, then each patient received 200 IU hCG (DICLAIR®) subcutaneous injection daily when the largest follicle mean diameter was 12 mm or larger starting on day twelve of menstrual cycle. Non-hCG group received 150 mg dose of CC from day 5 of menstrual cycle for 5 days, and both groups were monitored with transvaginal ultrasound. Ultrasound measurements of follicle number and growth, ovulation, endometrial thickness and pattern were recorded and compared between the two groups. Student t test and fisher exact test were used for statistical comparison between the two groups. Results: The low-dose hCG group had significantly higher percentage of ovula-tory cycles (80% vs 44.4% P value 0.006). There was no significant difference in the endometrial thickness between the groups but it appears higher in hCG group (10.55±1.82 vs. 9.62 ± 1.87 in non-hCG group, p value 0.056). Non significant but higher incidence of echogenic (luteinized) endometrium 48 hour post ovula-tion in hCG group (36/40 (90%) vs. 20/25 (80%) for non-hCG group p-value = 0.288). Conclusions: The use of low-dose hCG after CC in the late follicular phase re-sults in continued follicle growth, higher ovulation rate. This treatment offers an efficient and cost-effective alternative before gonadotropin therapy for this type of patients.
