睾丸中形成的精子,由于射精与精浆接触时,发生各种机能的、形态的、生化的特异变化。精子表面存在的精子膜抗原或物质(Substances)随着这些变化而变化,对受精有重要意义。这些物质之一是与伴刀豆球白A〔ConcanavalinA(Con A)〕特异结合的受体。精子面的ConA受体之研究很少以人为对象,与男性不孕的关系的报告尚未见到。作者的研究目标是:具有受精能的正常精液中精子与确认不孕症的精子减少症,无力精子症的精子表面ConA受体的分布区域、状态、区别,即在电子显微镜上形态相同的精子在生化上、质的方面有何差异。
Sperm formed in the testes, due to ejaculation and seminal plasma exposure, the occurrence of various functions, morphological and biochemical changes. Sperm membrane antigens or Substances that exist on the surface of sperm vary with these changes and are important for fertilization. One of these substances is a receptor that specifically binds to Concanavalin A (Con A). There are few reports of sperm-derived studies of ConA receptors on human subjects and no reports of male infertility have been reported. The authors’ research goals are: spermatozoa in fertilized normal spermatozoa and spermatogenic diseases to identify infertility, the distribution of spermai surface ConA receptors in spermatozoa, their status, and their differences, ie spermatozoa with the same morphology on electron microscopy In biochemistry, the quality of what is the difference.
