About

Records of women who had in vitro fertilization (IVF) or intra-cytoplasmic sperm injection (ICSI) in Dar AlTeb sub-fertility center will be reviewed and the follicular sensitivity index (FSI) will be calculated and correlated with pregnancy.

Full description

The investigators study is a retrospective cohort study. Records of women who had in vitro fertilization (IVF) or intra-cytoplasmic sperm injection (ICSI) in Dar AlTeb sub-fertility center from January 2010 to December 2013 will be reviewed. All records with missing data will be excluded.

Triptorelin 0.1mg (Decapeptyl® Ferring, Germany) was used for pituitary down-regulation. It was given 7 days after the expected time of ovulation in women with regular cycles. Women with irregular cycles were given combined oral contraceptive pills and triptorelin was started on day 21 after starting the pills. On the second day of menstruation serum FSH, LH, Prolactin and Oestradiol were assessed and the antral follicular count (AFC) was assessed using a vaginal ultrasound scan. AFC will be defined as the number of follicles measuring 3-10mm.

Controlled ovarian hyperstimulation (COH) was started on the 2nd day of menstruation using human menopausal gonadotrophin (HMG) (Merional® IBSA, Switzerland). The initial dose ranged between 150-300 IU/day. The COH drug dose was adjusted according to the patient's response guided by number and size of the follicles in addition to serum E2 values. COH was continued until at least 3 follicles ≥17mm were obtained. This was followed by the administration of Human chorionic gonadotrophin (HCG) (Choriomon®, IBSA, Switzerland) 10000 IU. On the day of HCG administration, ovarian ultrasound scan will be performed using a transvaginal probe and the Preovulatory follicle count (PFC) was assessed, (PFC) was defined as number of follicles measuring≥16mm. FSI will be calculated as (FSI =PFC*10000/AFC*Total dose of FSH) Oocyte retrieval was guided by transvaginal ultrasound and was done 34-36 hours following HCG administration. Fertilization was done by ICSI. 16-18 hours later, fertilization was confirmed by the presence of 2 pronuclei.

The procedure was cancelled if less than 3 follicles ≥17 mm in size are present 12 days after starting FSH despite doses reaching 450 IU. The cycle was also cancelled if there is risk of ovarian hyperstimulation like massive ovarian enlargement or serum estradiol exceeds 3000pg/L The quality of embryos was assessed at day 3 according to the number and evenness of blastomeres in addition to the percentage of fragmentation. Embryos were classified into 3 groups: Excellent embryos containing 6-8 even blastomeres with <10% fragmentation, moderate embryos containing 6-8 even or uneven blastomeres with 10-20% fragmentation, and poor quality embryos containing less than 6 blastomeres or >20% fragmentation.

Embryo transfer was done on the 5th day after oocyte retrieval for couples who had IVF/ICSI. If possible, 2 embryos were transferred and cryopreservation of the remaining embryos was offered.

Luteal support was given in the form of progesterone vaginal tablets (Prontogest® IBSA, Switzerland) 400mg/day starting from the day of oocyte retrieval. A pregnancy test was done 2 weeks after embryo transfer and clinical pregnancy was defined as the presence of an intrauterine gestational sac 5 weeks after embryo transfer.
