If the acrosome reaction is not functioning in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI), in which the sperm is injected in the egg may be necessary, whereas intrauterine injection (IUI) in which the sperm is placed within the cervix, will not be effective. In addition, it also can increase success. Additionally, it can predict the level of intervention required during assisted reproductive treatments. ICSI enhances fertilization in cases of very low sperm count, poor motility, or a high percentage of abnormal sperm. This test of sperm function can explain infertility in the cases of normal semen analysis when no female infertility factors are present. The results of this test indicate the quality of the sperm’s acrosome. Male infertility is due to low sperm production, misshapen or immobile sperm, inability to have intercourse (erectile dysfunction) or blockages that prevent. The acrosome reaction test uses a trigger, such as hormones or certain electrolytes to trigger the acrosome reaction sequence in a lab and evaluates the sperm’s performance. While a standard sperm analysis can visually test the sperm for the presence of a typical acrosome, it cannot test the acrosome’s ability to function normally when introduced to an egg. There are several tests that evaluate sperm. What are the Causes of Male Infertility When the semen analyses are abnormal, the urologists evaluation may reveal the source of the problem.
