ANATOMY

Detailed explanation-1: -The cervix opens anteriorly into the uterine body. About an inch long, the body of the uterus serves as a connection between the two uterine horns and the cervix. The uterine body is the site where semen should be deposited during artificial insemination.

Detailed explanation-2: -Vagina. The passageway through which fluid passes out of the body during menstrual periods. It is also called the “birth canal.” The vagina connects the cervix (the opening of the womb, or uterus) and the vulva (the external genitalia).

Detailed explanation-3: -At coitus, human sperm are deposited into the anterior vagina, where, to avoid vaginal acid and immune responses, they quickly contact cervical mucus and enter the cervix. Cervical mucus filters out sperm with poor morphology and motility and as such only a minority of ejaculated sperm actually enter the cervix.

Detailed explanation-4: -The sperm enters the female body through the vagina. From the vagina, it enters the cervix and passes on to the uterus. The egg released from the ovary is present in the fallopian tube. So, the sperm passes on to the fallopian tube from the uterus to fertilise the ovum.

Detailed explanation-5: -The Sperm’s Journey to the Egg Leaving the cervix they enter the womb. Here, they swim towards the Fallopian tubes. The vagina and the womb are quite hostile environments for sperm, however, once the sperm reach the Fallopian tubes they are mainly free from the potential negative effects of the woman’s immune system.
