Yes, a 100-year-old man can theoretically get a woman pregnant. While sperm production typically decreases with age, some men can remain fertile even into their 70s and 80s. However, it's important to note that the chances of conception significantly decrease with age, and there are numerous health risks for both the man and the child.
Factors that affect a man's fertility with age include:
- Sperm count: Sperm production naturally decreases with age, leading to a lower sperm count.
- Sperm motility: The ability of sperm to move and reach the egg can decline with age.
- Sperm morphology: The shape and structure of sperm can become abnormal with age, making it harder to fertilize an egg.
- Increased risk of health problems: Older men are more likely to have health conditions that can affect their fertility, such as prostate cancer or diabetes.
It's crucial to consider the following:
- Health risks for the child: Older fathers have a higher risk of transmitting genetic disorders to their children.
- Challenges for the parents: Raising a child at an advanced age can be physically and emotionally demanding.
While it is technically possible for a 100-year-old man to impregnate a woman, it is highly improbable and carries considerable risks.
