چکیده
Objective: Aim of this study was to identify the necessity of use of exogenous or surrogate LH for triggering of ovulation in induced cycles. Materials and methods: This study was conducted in Infertility Care and Research Center (ICRC) Dhaka, Bangladesh. Three hundred anovulatory patients with polycystic ovarian syndrome (PCOS) were the target population for this study. The patients were treated by different ovulation inducing agents to produce mature follicles. When follicle got the size of 18 mm or more LH was given to 150 patients (Group A) and 150 patients did not receive LH (Group B). Follicular rupture was monitored by USG. Main outcome measure was rupture of the follicle. Result: In group A 33.33% and in group B 34.67% patients responded by letrozole only, whereas 66.66% in group A and 65.34% in group B needed additional drugs like metformin glucocorticoids and gonadotropins. In both the groups response was similar in terms of number of follicular recruitment, follicular maturity, endometrial development and hormone production. Follicular rupture rate was similar in both hCG and non-hCG treated group. LUFS was detected only in 2.67% in group A and 2% cases in group B. Conclusion: If follicular development is adequate exogenous LH is not necessary for triggering of ovulation in all stimulated cycles. Key Wards: Induced cycle, Follicle, Rupture, LH Bangladesh J Obstet Gynaecol, 2011; Vol. 26(2) : 72-76

متن کاملI-25: GnRHa Trigger State of the ART -Towards the OHSS Free Clinic
Human chorionic gonadotropin (hCG) has been used as a surrogate for the mid-cycle LH surge for several decades. Due to structural and biological similarities with LH, hCG binds to and activates the same receptor - the LH/hCG receptor. However, despite the fact that hCG effectively secures final oocyte maturation and ovulation, its use as a surrogate for LH has got several drawbacks - first and ...

متن کاملCortisol interferes with the estradiol-induced surge of luteinizing hormone in the ewe.
Two experiments were conducted to test the hypothesis that cortisol interferes with the positive feedback action of estradiol that induces the luteinizing hormone (LH) surge. Ovariectomized sheep were treated sequentially with progesterone and estradiol to create artificial estrous cycles. Cortisol or vehicle (saline) was infused from 2 h before the estradiol stimulus through the time of the an...
