| description | Objective: To study the efficacy of a simple protocol of natural cycle in vitro fertilization.
Method: A retrospective study of 59 natural treatment cycles in 37 infertile couples with previous unsuccessful attempts of conventional in vitro fertilization.
Results: In 24% of cycles, the aspiration was cancelled because of inadequate visualization of follicles or because of preterm ovulation. Aspiration was performed in 45 cycles with oocyte retrieval of 82% per aspiration. Embryo transfer was performed in 30 cycles, pregnancy rate per pick-up was 15%.
Conclusion: In vitro fertilization in a natural cycle is a simple, relatively cheap and comfortable procedure with reasonable results and can be offered to patients scheduled not only for in vitro fertilization because of tubal factor but also to patients with endometriosis or unexplained infertility. |
