Document Summary
By administering smooth muscle stimulants to increase: fertilization. Physical nature of the ejaculate, phagocytosis, contractility of reproductive tract, cervical secretions and ability to navigate through cervical mucus. Low viscosity, in basal areas of cervical crypts, reservoir. What are the two types of ai techniques? insemination. Intracervical insemination is within the cervix and transcervical bypasses the cervix. Low ph, mucins, neutrophils, retrograde loss, sperm-sperm competition. T/f: capacitation is species specific false: capacitation is non species specific. Hold sperm in check (prevents penetration of epididymis and vaginal wall), and as seminal plasma is removed, the sperm gains the ability to penetrate the oocyte. What happens when the sperm becomes hyperactive in the oviduct? change from linear to frenzied in the oviduct to facilitate sperm-oocyte contact. Catsper protein acts to open ca2+ channels and increase motility. T/f: the zona pellucida is species specific true: the zona pellucida is species specific sperm egg binding.
