Fertilization by Microinjection of Human Sperm in Hamster and Human Oocytes

The interest of human sperm injection in the periovular space (SIPOS) is to study the fertilizing capacity of one or several human sperm selected on the basis of their phenotype (morphology and mobility). This approach can provide new information on the male gamete with the study of individual sperm rather than a heterogeneous sperm population.
