HOW DOES CONCEPTION OCCUR?
When the male sperm unite with the female egg in the fallopian tube, conception occurs. At the time of ejaculation, the sperms are protected by thick and sticky seminal fluid, which liquefies after about 15 20 minutes, making the sperms loose their protective covering. The secretions of the vagina are acidic. The sperms are sensitive to acids and those that have not entered the cervix during these 15 to 20 minutes are killed. Most of the sperms killed are immature, damaged or abnormal and therefore not suitable for conception. The alkaline secretions of the cervix nourish the sperms that have entered. Also at the time of the ovulation, secretions of the cervix become thin, transparent and most suited for the sperms to enter the uterus (cervical mucus). The sperms take about 45 minutes to travel from cervix, through the uterus and inside the fallopian tube. The secretions of the fallopian tube being alkaline and rich in sugar, provide nourishment to the sperms and help them survive for
