Fertilization in humans follows a complex series of events including binding of the sperm to the oocyte plasma membrane, oocyte activation, the completion of meiotic maturation of the oocyte with the extrusion of the second polar body, the decondensation of the sperm nucleus and the maternal chromosomes into male and female pronuclei and the restoration of the sperm centrosome. This duplicates and separates, forming two mitotic spindle poles upon which the parental genomes can intermix to complete fertilization. The use of intracytoplasmic sperm injection (ICSI) has been highly effective as a treatment for severe male infertility and thousands of ICSI babies have been born world-wide. Working with rhesus monkey gametes, we have developed a preclinical animal model for understanding the cell biological basis of ICSI. Typically, ICSI results in abnormal nuclear remodeling during sperm decondensation due to the presence of the sperm acrosome and perinuclear structures normally removed at the oolemma during in vitro fertilization. These unusual modifications raise concerns that the ICSI procedure itself might lead to the observed increase in chromosome anomalies reported for
