Journey of sperm to ovum

How long sperm live… The details of their journey… The variables for survival! Today, we know that this is not the case, and that sperm health is just as important as regular, predictable ovulation and overall menstrual health. In other words, it does in fact take two to tango. A woman must indeed ovulate — but for a pregnancy to be achieved, healthy and motile sperm must be present to fertilize the egg.

The Sperm Journey to the Egg - Exseed

The male and female parts of the human reproductive system can bring together an egg and a sperm so that they join and begin the development of a new human being. The female system also protects and nourishes the developing foetus during the nine months of pregnancy. Sperm are made in the testes and mature in a coiled tube, the epididymis. At the end of sexual intercourse, they travel along the vas deferens and mix with fluids made by the prostate gland and seminal vesicle.

Fertility Basics

Fig 1. The journey begins with millions of sperm cells that are released into the female reproductive tract during intercourse. The sperm cells gain their full ability to swim when they are ejaculated into the reproductive tract [ 1 ],[ 2 ]. Upon ejaculation, the sperm cells are enclosed in a fluid called seminal plasma or semen, which is a mix of fluids from the testes, seminal vesicles, prostate, and the bulbourethral glands.

Suarez, A. 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. In the uterus, muscular contractions may enhance passage of sperm through the uterine cavity. A few thousand sperm swim through the uterotubal junctions to reach the Fallopian tubes uterine tubes, oviducts where sperm are stored in a reservoir, or at least maintained in a fertile state, by interacting with endosalpingeal oviductal epithelium.
