COMPARISON BETWEEN TWO FET CYCLE METHODS WITH AND WITHOUT URINARY LH SURGE MEASUREMENT WITH URINARY LH KIT

The objective of this study is to assess the effectiveness of adding urinary LH surg e kit to hormonal prepared frozen embryo transfer (FET) cycles. In this prospective clinical trial, 48 patients enrolled in two groups. Endometrial hormone priming in both groups was similar; but i n group A, from day 10 of cycle, urinary LH surge detection was started embryo transfer (ET) scheduled after first positive test. In group B, ET was done after reaching endometrium thic kness to at least 7 mm. The duration of cycle, the frequency of ultrasound monitoring, the total dosage of estrogen consumption an d the result of cycle were measured. The duration of cycle before ET in group A was shorter (8.79 ± 1.14 VS 11 ± 1.47 days, P Value: 0.0005), the number of ultrasound repetition also was lesser (2.42 ± 0.58 VS 3.67 ± 0.86, P Value: 0.001). Respectively, in group A the total dosage estrogen consumption was less than group B (35.58 ± 5.2 VS 46.83 ± 5.27 mg, P value: 0.0005). The pregnancy rate in group A was more than group B, although it was not significantly different ( 37.5 % VS 25 % , P value: 0.52). It see ms except endometrial characters, assurance about the best time for embryo implantation prevent wasting valuable frozen embry o by incorrect timing of thawing and transfer.
