His Fertility:
Testicles and their role in conception

The testicles play a vital role in conception.
There are many factors about this part of the male's body that need to be right for conception.

For starters, they are built outside a mans body for a reason.

For optimum fertility the mans testes need to be a slightly lower temperature then the rest of the body, so having them hang outside of the body helps the male to keep them cooler.

Some men worry if theirs are too small or too big, but the size of them really doesn't generally interfere their ability to conceive. There can be an array of common problems that men experience preventing them from being able to help the woman conceive.
Let's explore in more depth below.

What Might Impede Fertility For A Male?

Does your partner have undescended genitals?
Men who have this problem usually have lower sperm counts, poorer quality sperm and lower fertility rates than men whose descend normally, so if you think your partner might fall into this category it may be worth a trip to a fertility specialist for further investigation.

What To Avoid

---

Avoid overheating by wearing looser fitting underwear like boxer shorts, and give the tighter undies a miss whilst trying to conceive.

---

Avoid long hot baths, sleeping on a warm water bed (or with an electric blanket going). Even sitting for long periods, say on a long drive can trap heat, so make sure you get up every now and then for better air circulation and to avoid the temperature of the balls rising.
