钙(Ca)在体内作用于细胞膜和细胞内,在各种机能中起重要作用,但在精子的运动能和受精能的获得,精子顶体反应,精子和卵子结合等生殖现象中,Ca也起重要的作用。另一方面作为决定妊娠现象的因子-宫颈粘液(CM)与精子运能的关连,具有重要的意义。CM性状随卵巢周期而变化,影响着精子的CM穿透性和向宫腔运行能力。作者每日测定排卵前后的CM内的Ca浓度、观察Ca浓度周期性变化、同时研究体外和体内的Ca浓度和精子运动能,CM贯穿性,Y精子比率的
Calcium (Ca) plays an important role in various functions in the body and in cell membranes. However, in the reproduction of sperm motility and fertilization, sperm acrosome reaction and sperm and egg binding, Ca Play an important role. On the other hand, it is of great significance as a factor that determines the pregnancy phenomenon - the relationship between cervical mucus (CM) and sperm transport capacity. CM traits vary with the ovarian cycle, affecting the sperm’s CM penetration and its ability to function in the uterus. The authors measured the Ca concentration in the CM before and after ovulation, observed the periodic changes of Ca concentration, studied the concentration of Ca in vitro and in vivo and the kinetic energy of sperm, CM penetration, Y sperm ratio
