Background: The study was conducted to evaluate the efficacy of urinary LH surge kits and TVS to detect ovulation in induced cycles and to compare the ovulation rates by both methods.Methods: Prospective experimental randomized control trial on 72 women with an ovulatory infertility aged 18-35 years, fulfilling the inclusion criteria were given letrozole for ovulation induction. All were randomly divided in two groups. Group 1 woman were asked to check ovulation by urinary LH surge kits and group 2 women were called for follicle monitoring by TVS.Results: Letrozole has no negative effect on endometrium; induced cycle has larger diameter of follicle (median: 22 mm). In induced cycle ovulation occurs later compared to normal cycle (D-16) and half of the women had a BMI more than the recommended WHO criteria (average was 25.28 kg/m2). Number of letrozole cycles (p=0.2642), dose requirement (p=0.0812) and pregnancy rates (10.26% versus 18.19%) were comparable in both groups.Conclusions: TVS is objective, accurate and thus standard modality for ovulation detection. LH surge kit is subjective, having more chances of error but can be used as a good alternative in certain settings like woman of remote area, woman having fear of invasive modality and COVID era woman who are afraid to visit hospital repeatedly.
