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 incidence and types of major congenital malformations (MCM) in liveborn children conceived by intracytoplasmic sperm injection (ICSI). METHODS: a total of 680 liveborn children resulted from 511 couples submitted to ICSI from January, 1999 to December, 2002. Data collection of the children was performed through standardized questionnaire and clinical examination. Of the 511 couples, 366 had been contacted for a sampling of 371 gestations. Of the 680 liveborn, 520 had been evaluated, 250 of them (48.1%) through questionnaire and 270 (51.9%) through questionnaire and physical examination. Two hundred and fifty children were from singleton pregnancies and 270 from multiple pregnancies. Malformations were classified according to the 10th revision of the International Statistical Classification of Diseases and Related Health. Only MCM were analyzed in this study. The incidence of MCM was compared with that of the general population obtained by the Latin American Collaborative Study of Congenital Malformations. The statistical analysis was performed by the c² test (level of significance p<0.05). RESULTS: of the 520 children, 15 presented MCM, resulting in an incidence of 2.9%. There was no difference in relation to the control group (p>0.05), which showed 2.6% incidence of MCM. The most frequent malformations were of cardiac origin (four isolated and two associated), corresponding to 40% of the total. The other types of MCM were: renal (three), neural tube (two), skull (one), cleft lip (one), genital (one), Down syndrome (associated with cardiac malformations) (two), and musculoskeletal (one). Six MCM occurred in children from singleton pregnancies and nine in children from multiple pregnancies. CONCLUSION: the liveborn children conceived by ICSI presented incidence of major congenital malformations (2.9%) near to the expected for the general population (2.6%). However, to establish the risks of MCM with precision it is necessary to continue the evaluation of the children conceived by ICSI.
