人类的精浆中含有惊人量的前列腺素,大多数为PG_K类,其含量从100～500μg/ml,但是这些精浆PGs的生物学机能至今尚未弄清。有些作者提出,PGs在排卵前可以改变精子向宫颈粘液的穿透。为了进一步评价这种假设,作者测定了排卵前宫颈粘液中的PGs。从23例年龄18～43岁的健康妇女收集到宫颈粘液,所有受试者的月经规律,其中5例带有宫内节育器。根据基础体温,在排卵前期收集宫颈粘液。
Human seminal plasma contains a surprising amount of prostaglandins, most of which are PG_K, ranging from 100 to 500 μg / ml, but the biological function of these PGs has not been elucidated yet. Some authors suggest that PGs alter the penetration of sperm into cervical mucus before ovulation. To further evaluate this hypothesis, the authors measured PGs in cervical mucus prior to ovulation. Cervical mucus was collected from 23 healthy women aged 18-43 years, with regular menstruation in all subjects, 5 of whom had an IUD. According to basal body temperature, cervical mucus is collected before ovulation.
