At what age does a man stop producing viable sperm?

Most men make millions of new sperm every day, but men older than 40 have fewer healthy sperm than younger men. The amount of semen (the fluid that contains sperm) and sperm motility (ability to move towards an egg) decrease continually between the ages of 20 and 80.

What are the signs of healthy sperm?

Now, let’s define the elements of healthy sperm:

• Quantity (volume). A healthy sperm count is about 15 million or more for every milliliter (mL) of semen.
• Movement (motility). Not every sperm moves effectively or even at all, but this is normal.
• Shape (morphology). Healthy sperm have rounded heads and long, strong tails.

Can a little drop of sperm make a woman pregnant?

Pregnancy is possible whenever semen is in or on the vagina. But getting pregnant by wiping is unlikely, especially if the semen is not fresh or only a small amount enters the vagina. However it happens, if fresh semen enters the vagina of a person who can conceive, pregnancy becomes a possibility.
