Using Microfluidic Separation Sperm Selection for Unexplained Infertility and Reccurrent Implantation Failure

Patients will be treated with conventional IVF treatment. A vaginal ultrasound (US) examination will be perform on day 3 of the cycle for assessment of ovarian size and to exclude patients with large ovarian cysts. If a cyst \>20 mm is present, the cycle will cancel. At an initial dose of 225 IU, hMG will be given daily by IM injection commencing on day 3 of the cycle. The dose will be adjusted as re- quired depending on the E2 (estradiol) level. Daily endovaginal US examinations for follicle growth assessment will be started when the E2 level reached 275 pg/mL (1,000 pmoljL). When at least two follicles would reach 18 mm in diameter, 5,000 IU of hCG will be administered intramuscularly. Oocyte retrieval will be performed vaginally under US guidance 36 hours later. Sperm for ICSI procedure of oocytes will be prepared by a standard swim-up technique using for control group and sperm chip method will be used for study group for Unexplained Infertility and Recurrent Implantation Failure group. Uterine transfer of embryos will be carry out fifth day after oocyte retrieval using a catheter.
