Sperm in its journey through the female reproductive tract?

Sperm is the male reproductive cell. Sperm are made in the testicles and are made from a different type of cell than an ovum (egg). The sperm is the only cell that can produce an egg.

Sperm cells have three parts: head, midpiece, and tail. The head contains genetic material called DNA; this controls how your baby looks when it grows up! The midpiece provides energy for movement through liquid like water or milk; if you put your finger into milk, it feels slippery because there are lots of tiny sperm swimming around in there! The tail helps them swim towards an egg so they can fertilize it with their DNA before dying off soon afterward - which means no more babies after this point!

How do sperm get made?

Sperm are made in the testes. They're produced in a pair of organs called seminiferous tubules located within the scrotum, an external organ that hangs outside of your abdomen (the part below your belly button). The sperm then travel through a tube called the epididymis and are stored there until they're ready for release into the ejaculate.

The testes can also be thought of as factories where sperm cells are made--they have machinery inside them that produces these tiny cells at lightning speed!

How do sperm get released?

Sperm is released from the testicles into the epididymis, a tube that sits on top of each testicle. The sperm travels through this tube for about two weeks before traveling through another tube called the vas deferens and into the urethra, or pee hole.

This is where the sperm leaves the body and is ejaculated. The testicles also produce testosterone, which is what makes men masculine.

Testosterone is the male sex hormone that is responsible for the development of male sexual characteristics and secondary sex characteristics. It is also important in maintaining muscle mass and strength, bone density, hair growth, fat distribution, and red blood cell production.

How many sperm are in a human male ejaculate?

The volume of semen that's ejaculated varies from man to man, but it's usually around a teaspoon or a little more. The number count of sperm in the ejaculate also varies among men; it all depends on your age and health and other factors like diet and exercise.

A healthy male aged 20-29 should have between 40 million (population average) and 300 million (high) sperm per milliliter of semen. Men over 60 often have less than 20 million/ml. As you get older, your semen volume may also decrease slightly; however, this is normal for most people who live long enough.

How long does it take for sperm to travel and reach the ovum?

Sperm can swim at a rate of about 1 millimeter per minute. It will take about 20 minutes for sperm to travel from the epididymis, where they are stored, to the female reproductive tract. Once there, they must travel through the fallopian tubes (about 10-12 cm long on average) before reaching an egg cell.

Once in contact with an ovum (or egg), sperm will have only about 24 hours before its lifespan ends, and it dies inside your body.

What if the sperm doesn't make it to the ovum?

There are several other ways that sperm can die before they reach the ovum. Sperm can be blocked by cervical mucus, which your body produces to keep out foreign objects like bacteria and viruses. If you have a higher concentration of sperm than normal in your cervix, it will block more of them from entering your uterus.

If an egg has already been fertilized by another sperm cell (called "polyspermy"), then another one might not be able to penetrate through its outer layer--this would cause it to die as well! And if there aren't enough nutrients available for all those little guys down there, they'll start eating each other until only one remains victorious over all others and then dies because he didn't get any food either way.

Sperm is a tough little guy, but a lot can stand in its way.

You might be surprised to learn that sperm is a tough little guy. It's not just a blob of goo; it's made up of many different parts that can be affected by many things.

The environment, the male, and the female body affect sperm health. For example:

• The amount of heat that you're exposed to can affect how well your sperm swims (or doesn't). Sperm cells are sensitive to temperature changes and can die off if they get too hot or cold If you're trying for a baby in the summertime when temperatures are high outside but cool inside your house...your chances could decrease!
• Smoking cigarettes has also been shown to reduce fertility because it reduces blood flow through the testes, affecting how much testosterone (a hormone needed for healthy sperm production) is produced there.*

Conclusion

It's amazing how much work goes into creating just one sperm cell. From its first appearance in the testes as a stem cell, it travels through many different stages before becoming fully developed and ready for release. Then, once it leaves its home base inside the male body, it has to go through the female reproductive tract before finally reaching its target: an egg cell that could produce offspring if fertilized by another sperm. It might seem impossible for something so small--but then again, we wouldn't be here without these little guys!
