PURPOSE: to evaluate the efficacy of in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI) in natural cycle (NC). METHODS: retrospective clinical trial that evaluated 70 treatment cycles in 60 couples that were submitted to IVF treatment with ICSI in NC performed in private clinic from 1999 until 2003. It was performed daily ultrasound monitorization or on alternate days, and urinary LH dosage when the follicle reached 16 mm of diameter. It was scheduled egg retrieval when the follicle reached 18 mm of diameter and 36 hours after hCG administration when the LH test was negative. Embryo transfer was performed 48 to 52 hours after ICSI. RESULTS: 70 ICSI cycles in 60 patients were performed and the indications of treatment included: male factor (47.1%), tubal factor (37.1%), associated factors (8.7%), unknown infertility (7.1%). Out of 70 cycles, 18 cycles were cancelled (25.7% of cancellation rate). Out of 52 patients that were submitted to ovarian punction to oocyte retrieval we found mature oocytes in 77% of the cases (40 cycles), in four cases we collected immature oocytes and in eight cases we could not found it. We had 70% of fertilization rate and only one fertilized oocyte did not achieve the cleavage stage. So, the transfers rate per punction and per mature oocyte was 52% and 67.5%, respectively. We had 11.4% of pregnancy rate per cycle, 15.4% per punction and 29.6% per embryo transfer. CONCLUSIONS: FIV/ICSI in NC seem to be a satisfactory option of treatment, with low costs and complications (multiple gestation and Ovarian Hyperstimulation Syndrome), mainly in poor responder patients and in poor populations.

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.
