I reviewed the 20 pregnancies after In Vitro Fertilization and Embryo Transfer in EWHA Woman's University Hospital from 1990 September to 1994 December.
@ES And the Results were as follows.
@EN 1) The mean age of patients were 31.7±3.9 and the average duration of infertility was 4.3±2.3years.
2) The major cause of infertility was tubal factor and especially bilateral tubal obstruction was most frequent.
3) Controlled Ovarian Hyperstimulation methods were FSH/hMG and GnRH-agonist/FSH/hMG(long, shohrt, and ultrashort protocol). Long protocol using GnRH-agonist/FSH/hMG had the highest pregnancy rate (35.3%).
4) Regarding the response to controlled ovarian hyperstimulation, serum estradiol level on the day of hCG administration(Do) was 3169.4±3611.5pg/ml. Do endometrium thickness was 9.3±2.7mm, the number of aspirated oocytes was 9.8±7.1, the
number
of
preovulatory oocytes was 9.3±14/7.4mm, the number of cleaved oocytes was 6.1±6.3 and so fertilization rate was 66.3%.
5) The outcomes of pregnancy comprised chemical pregnancy(2 cases0, abortion(7 cases), ectopic pregnancy(1 cases), and ongoing pregnancy (1 cases). As cosidered the number of fetus, singleton pregnancy was in 13 cases(76.4%) and twin pregnancy
was
in 4
cases(23.5%).
