Publisher Summary Successful in vitro fertilization (IVF) may be approached by either of two methods that differ substantially in concept. One method of obtaining normal oocytes for IVF is to rely on the precise determination of periovular changes to predict the exact time of ovulation in the natural or spontaneous ovulatory cycle.

The whole fertilization process can be affected by the presence of iso or auto-antibodies or even Fab fragments against specific antigens involved in fertilization like FA1 sperm surface antigen and ZP1, ZP2 and ZP3 oocyte surface antigens. These knowledges can be used to develop a natural vaccine (FA1 seems to be able to inhibit fertilization).
