[Perinatal result of an institutional assisted reproduction program].
BACKGROUND
Assisted reproductive technology manipulates masculine gametes, embryos and implantation. It also aids the known or unknown factor of sterility without having the base problem correction as a target. In vitro fertilization and embryo transfer are among these techniques.


OBJECTIVE
To describe the overall outcome and the final perinatal offspring after in vitro fertilization cycle in an institutional third level hospital.


METHODS
IVF cycles were retrospectively analyzed from October 1999 to May 2004. Several variables were described like: age, fertilization rate, implantation and pregnancy rate, fetal status, time of gestation during labor, miscarriage follicle-stimulating hormone rate and take-home baby rate. Patients underwent hypophyseal supression with GnRH analog, using a long luteal phase protocol and stimulated with recombinant FSH. Overall data is expressed as average +/- standard deviation and percentage.


RESULTS
365 cycles were analyzed in 314 patients, average age was of 34 +/- 3.7 years, tubal factor was diagnosed in 63.3%, fertilization rate was of 60.4%, implantation rate of 37.1%, per transfer pregnancy rate of 25.1%, per transfer live born rate of 21.7%, multiple pregnancy rate of 29.3%, miscarriage rate of 28% and ectopic pregnancy rate of 4.8%. In 87.8% of the cases caesarean operation was made; multiple pregnancy offspring weighted more than 1250 g in 70% of them; 70.5% was born after 32 weeks of pregnancy; 90% was born live and with good prognosis. Glucose metabolism alterations were the most frequent maternal complication.


CONCLUSIONS
Although the results obtained were similar to those of assisted reproduction centers, it suggests improving multiple pregnancy rate and abortion rate.
