PURPOSE: to evaluate the experience of an assisted reproduction center that uses depot administration of half-dose of GnRH agonist for pituitary suppression in assisted reproductive cycles. METHODS: prospective study that evaluated in vitro fertilization or intracytoplasmatic sperm injection (IVF/ICSI) cycles utilizing half-dose of leuprolide acetate between August 2005 and March 2006. Recombinant FSH was administered for controlled ovarian induction based on the protocol. hCG was administered when at least one follicle reached 19 mm in diameter. IVF or ICSI was performed according to infertility factor. Up to four embryos were transferred on the second or third day after oocyte retrieval. Progesterone supplementation was initiated on the same day of oocyte retrieval, and after 14 days beta-hCG was measured. The following parameters were evaluated: number of aspirated cycles, cancelled cycles, transferred cycles, total dose of FSH employed, number of mature oocytes retrieved, fertilization rate, number of transferred embryos, embryo implantation rate, and pregnancy rate. RESULTS: A hundred and nine IVF/ICSI cycles were initiated. The mean age of the patients was 34.9 years. We observed 1.8% of cancellation rate. The mean total dose of gonadotrophins employed was 1,905 IU per cycle. We obtained 86.5% of mature oocytes and the fertilization rate was 76.3%. The mean number of embryos transferred was 2.7. Pregnancy rates per aspiration and per transfer were 25.2 and 25.7%, respectively. Of those who reached pregnancy, 26.3% were twins and 5.3% were triplets. CONCLUSIONS: the half-dose of GnRH depot employed for pituitary suppression was a useful alternative for ovarian stimulation in IVF cycles because it is comfortable and practical for the patient, besides its low cost.

PURPOSE: to evaluate the first in vitro fertilization results at a medical university using low-cost programmed cycles. METHODS: from May to December 2002, 66 programmed cycles of in vitro fertilization were carried out using norethisterone acetate, clomiphene citrate and human chorionic gonadotrophin (hCG). The ovarian follicle aspiration was guided by ultrasonography, 34 to 36 h after the administration of hCG, and the embryo transfer, 48 h after puncturing. The diagnosis of clinical pregnancy was defined when a pulsating heart was detected by transvaginal ultrasonography. RESULTS: the cycle cancelation rate was 21.2%. An average of 2.8 follicles and 1.7 oocytes were obtained per puncture. In 79.6% of the punctured cycles it was possible to retrieve oocytes and 69% of them were fertilized. The number of embryos per transfer was 1.5. Some level of difficulty occurred in 10.2% of the aspiration procedures and 32.4% in the embryo transfer. The obtained pregnancy rate was 10,8% per transfer; however, the drug cost per transferred embryo was only R$ 96,00. CONCLUSION: the difficulty to begin an in vitro fertilization program in a medical school, not aiming at profits and to help a population without financial possibilities, became evident. After progressive experience, the cumulative pregnancy rate tends to be similar to that of reference centers, but with significantly lower costs and incidence of complications.
