Comparison of Urinary LH Surge Kits and Transvaginal Sonography forOvulation Detection

Aim: The present study is to assess the effectiveness of urine luteinizing hormone (LH) surge kits in comparisonto transvaginal ultrasonography (TVS) for the detection of ovulation in ovulatory infertile women.Methods: This observational research, conducted at Department of Obstetrics and Gynaecology, Patna MedicalCollege and Hospital, Patna ,Bihar, India involved 84 ovulatory infertile women aged 18 to 35 with normal semenanalysis. Patent tube Participants were randomized into two groups: Group 1 utilized urine LH surge kits, whereasGroup 2 received transvaginal sonography monitoring. All participants were administered letrozole for thepurpose of ovulation induction. The primary objectives were the rates of ovulation confirmation; the secondaryoutcomes encompassed letrozole dose, conception rates, and follicular size at the time of ovulation. Statisticalanalyses were conducted with SPSS.Results: Ovulation was verified in 83.3% (35/42) of Group 1 and 90.5% (38/42) of Group 2 (p=0.35). The meantime to ovulation detection was consistent at 20 hours (p=0.92). Conception rates were comparable: 51.4 percentin Group 1 and 52.6 percent in Group 2 (p=0.92). The mean follicular diameters at ovulation were 20.5 mm forGroup 1 and 20.3 mm for Group 2, demonstrating no significant differences.Conclusions: Urinary LH surge kits are equivalent to transvaginal ultrasound for identifying ovulation in ovula-tory infertile women, offering a less intrusive and more economical option without jeopardizing fertility results.These findings endorse the use of LH surge kits into fertility treatment strategies.
