Typically, the average ejaculation contains 2-6 milliliters of semen, which amounts to about a half to a full teaspoon. A lesser amount of semen, on average, may not be enough to achieve pregnancy; whereas any more than that could dilute the sperm concentration.
You might ask yourself why it is so important for the father to have a healthy sperm count, if only one is needed for fertilization? For one thing, the journey to the egg isn’t easy for the sperm; it has to make its way through the vagina to the fallopian tubes. The average ejaculation can contain around 100 million sperm, but only few of them make it all the way to the fallopian tubes. If a man has less than 20 million sperm per milliliter of semen, it’s possible that he could be at risk for infertility. The sperm has to be particularly healthy to reach the egg.
Besides sperm count, semen can also be analyzed based on motility and morphology. The sperm motility refers to the percentage of sperm that is motile, meaning can swim well. The Advanced Fertility Center of Chicago experienced that men with a motility over 45% tend to be fertile.1
Typically, semen is thick directly following ejaculation and becomes thinner within 10 to 15 minutes. The motility can be restricted due to thickness. A semen analysis can also test for morphology, which analyzes the size, shape, and appearance of sperm. Any defects can be detected using this method.2
Some prospective fathers choose to have a semen analysis done in the course of the TTC journey to determine whether or not they are experiencing infertility issues. Generally speaking, the health of sperm often acts as a mirror of a man’s overall health. If a man is physically fit, eats healthfully, and abstains from smoking and excess drinking, then there is usually a high chance that his sperm is also healthy. [avafootnote]
