Brief summary

The main objective of this study is to compare the cumulative ongoing pregnancy rates of two different IVF protocols in women candidate for ART characterized by low prognosis.

Detailed description

The patients will be allocated into two groups: control and study group \_ In study group, patients will be treated by DuoStim protocol: The first phase of ovarian stimulation is started on the second day or third day of period. GnRH agonist will be used to trigger when at least two follicles ≥ 17 mm. Approximately 36 hours later, oocytes will be retrieved vaginally under ultrasound monitoring and ICSI will be performed. Five days later after oocyte retrieval, the second stimulation will be started. All embryos will be cryopreserved. \_ In control group, patients will be treated with antagonist protocol: The cycle of ovarian stimulation is started on the second day or third day of period. hCG will be used to trigger when at least two follicles ≥ 17 mm. Approximately 36 hours later, oocytes will be retrieved vaginally under ultrasound monitoring and ICSI will be performed. If serum progesterone on the day of trigger ≥ 1.5 ng/ml, all embryos will be cryostored; otherwise, fresh embryos will be transferred.

Design outcomes

Primary

MeasureTime frameDescription
Cumulative Ongoing pregnancy rateweek 11 - 14 of pregnancycalculated by the number of ongoing pregnancy patients divided by the total number of patients in appropriate group

Secondary

MeasureTime frameDescription
Ongoing pregnancy rateweek 11 - 14 of pregnancydefined as the pregnancy completed 11 - 14 weeks of gestation and having vital fetus
Number of oocytes retrieved4 hours after occyte pick-upNumber of oocytes retrieved identified by the embryologists
Pregnancy rate2 weeks after embryo transferbeta-hCG test is positive
Number of competent embryos3 days to 5 days after oocyte pick-upNumber of embryos that can be transferred
Fertilization rate1 to 3 days after oocyte pick-upnumber of fertilized oocyted divided by number of mature oocytes
Number of mature oocytes4 hours after oocyte pick-upNumber of mature oocytes identified by the embryologists
