[The hamster test. Practical consequences]

The result of the in vitro human sperm penetration test into hamster eggs must not be considered as absolute. It is a step in the management of male infertility and must be interpreted in regard of the results of other tests. In our experience, if the test is negative, the probability to observe a pregnancy in the patient's partner is about one in seven and half years; if the test is positive, it is about one in two and half years. On the other hand, if a pregnancy occurs, with a positive or a negative test, it will start 5 to 7 months later.
