Male infertility due to globozoospermia

Disease definition

Male infertility due to globozoospermia is a male infertility due to sperm disorder characterized by the presence, in sperm, of a large majority of round-headed spermatozoa that lack the acrosome and have an aberrant nuclear membrane and midpiece defects. The acrosomeless spermatozoa is not able to penetrate the zona pellucida and thus fertilization failures, even with intracytoplasmic sperm injection, are frequent.
