In vitro fertilization and embryo transfer has been used as a part of treatments for imfertility patients. Out IV-ET program began in June 1986 and first IVF-ET baby was delivered in December 8, 1991.
The number of treated subjects in our IVF-ET program were 447 and the number of total cycles of contolled ovarian hyperstimulation were 50. Ultlasound guided transvaginal follicle aspiration was successful in 48 cycles and success rate of
follicle
aspiration was 96%. The number of ova picked up were 322. The mean number or retrieved per follicle aspiration was 2.95. the maturity of 322 aspirated ova showed 50 preovulatory mature oocytes(15.2%), 219 intermediate(68.01%), 11 immature(3.41%),
42
postmaure(13.04%). Embryo transfer was done in 45 cycles(93.75% of successful aspiration cycles). The mean number of cleaved oocyte per aspiration cycle was 2.95 and successful cleavage rate after insemination was 44.09%. pregnancies were
obtained
in 21
cases. Clinical pregnancy rate per follicle aspiration was 18.7%%, clinical pregnancy rate per embryo transfer was 19.14%, of these 21 cases, there was 1 premature delivery(surrogate), 7 ongoing pregnancies (1 surrogate included), 1 combined
pregnancy
(intrauterine and tubal pregnancy) and 12 preclinical (chemical) pregnancies.
