www.neotiahealthcare.com Ovulation induction in IUI PERFORMANCE Dr.Shiuli Mukherjee MBBS,MD,FNB(Reproductive Medicine) Infertility & IVF consultant www.neotiahealthcare.com • 35 years old lady suffering from primary infertility, husband normozoospermic, HSG-B/L spillage positive, AMH- 1.5, had 6 cycles of ovulation induction with clomiphene citrate and timed coitus (unmonitored cycle), not conceived. Now planned for IUI (AIH). How to stimulate? • • • • CC + Gonadotrophin Anestrazole Continuous Gonadotrophin Continuous Gn + antagonist www.neotiahealthcare.com Learning Objectives At the conclusion of the presentation participants should be able to answer: • Why we need ovulation induction? • How to stimulate ovary? • How to monitor? www.neotiahealthcare.com Controlled ovarian stimulation in IUI cycle OBJECTIVE: To produce more than one egg for better chance of pregnancy www.neotiahealthcare.com Different drugs and stimulation protocols used for IUI 3 TYPES OF DRUGs 6 TYPES OF PROTOCOLS • Clomiphene citrate • 3 CONVENTIONAL • Letrozole/anestrazole • 3 NON CONVENTIONAL • GONADOTROPIN – FSH or HMG • GnRH AGONIST or ANTAGONIST www.neotiahealthcare.com Why different drugs and protocols? • All patients are not equal responders to a particular type of stimulation • Response basically depends on : • OVARIAN RESERVE - 3 A Age AFC (Antral follicle count) AMH (Anti Mullerian Hormone) • PELVIC PATHOLOGY • BMI www.neotiahealthcare.com AFC and AMH • AFC – follicles between 5-10 mm diameter on day 2 – 3 • AMH secreted by early antral follicles • Both predict ovarian response accurately.

Update 16(2), 113–130 (2010). www.neotiahealthcare.com Different protocols of stimulation CONVENTIONAL: • Cc with or without adjuncts • Cc with ‘soft’ gonadotropin stimulation – Scattered d3, d5, d7, d9 with cc – Sequential after completion of cc d5 or d7 – Fixed d3 & d8 with cc • Continuous low dose gonadotropin stimulation www.neotiahealthcare.com Our publication….
