When it comes to male reproduction, there’s quite a bit to unpack! Unlike women, who are born with all the eggs they will ever have and go through them until menopause, men have the ability to produce sperm throughout their lives, starting from puberty. Isn’t that fascinating?
The Role of Hormones in Sperm Production
Sperm production is regulated by hormones like follicle-stimulating hormone (FSH) and luteinising hormone (LH). LH plays a key role in triggering testosterone, which not only helps with sperm formation but also influences secondary sexual characteristics and libido.
The Journey of Sperm
So, here’s how it works: once puberty hits, the testes spring into action, generating millions of sperm cells. Initially, these sperm cells hang out in the testes for about 10 weeks before moving to the epididymis, where they mature for another two weeks. This is when they develop their tails and gain the ability to swim—pretty essential for their journey!
During ejaculation, muscle contractions propel the sperm through the seminal ducts and out of the urethra. If sexual intercourse occurs with someone who has female reproductive organs, the sperm then make their way through the vagina, cervix, and uterus to the fallopian tubes. If they encounter a mature egg there, they’ll attempt to penetrate it. If one sperm succeeds, it leads to fertilization—the start of a new life! However, with around 300-400 million sperm in a single ejaculation, most won’t make it anywhere near the egg. If sperm count or motility is below par, fertility can be affected.
The Importance of Sperm Motility
Speaking of sperm motility, this is actually the leading cause of male infertility. The World Health Organization has set some benchmarks for “normal” sperm motility, including:
- A minimum ejaculate volume of >2 ml
- A pH level above 7.2
- At least 40 million sperm cells overall
- A concentration of over 20 million sperm per milliliter
- More than 15% of those sperm are normally shaped
- Ideally, over 50% should show forward movement, or 25% should exhibit progressive movement within an hour after ejaculation
Next Steps for Fertility Challenges
If you’re curious whether sperm could be a factor in fertility challenges, a detailed sperm analysis can give you the answers you need. Depending on the results, your healthcare provider can guide you on what steps to take next.

Conclusion
In short, male reproduction is a complex but fascinating process that plays a crucial role in fertility. Understanding how sperm production and motility work can help navigate any challenges that might arise on the path to parenthood.
