Study of the Changes of Acrosomal Enzyme, Nitric Oxide Synthase, and Superoxide Dismutase of Infertile Patients with Positive Antisperm Antibody in Seminal Plasma.
The purpose of this article is to study the effect of positive antisperm antibody (AsAb) in seminal plasma on acrosomal enzyme activity, nitric oxide synthase (NOS) activity, and superxide dismutase (SOD) activity of spermatozoa. A total of 40 infertility patients with positive AsAb in seminal plasma were selected as experimental group, and 40 fertile males were selected as control group. Based on the changes in absorbance, the acrosomal enzyme activity was detected by the BAEE/ADH method, the NOS activity was detected by the redoxreaction assay, and SOD level was measured with xanthine oxidase method. Compared with the control group, acrosomal enzyme activity of spermatozoa of the experimental group was significantly decreased (P < 0.01), NOS activity was apparently increased (P < 0.01), and the SOD level in seminal plasma was significantly decreased (P < 0.01). The infertility caused by positive AsAb in seminal plasma may be related to the changes in the acrosomal enzyme of spermatozoa and the SOD and NOS activities in seminal plasma.
