The answer is the second one: The inability to fertilize an egg.

Explanation for each option:

1. The inability to have an erection - This describes erectile dysfunction, not infertility. Erectile dysfunction is a condition where a man has difficulty achieving or maintaining an erection, but it does not directly define infertility.

2. The inability to fertilize an egg - This is the correct definition of infertility. Infertility refers to the biological inability of a person to contribute to conception, which can involve issues with fertilizing an egg.

3. A sperm count lower than 100 million sperm/mL - While a low sperm count can be a factor in male infertility, infertility itself is not defined solely by sperm count. Infertility involves a broader range of issues that can prevent conception.

In summary, infertility is best defined as the inability to fertilize an egg, which encompasses a range of potential biological issues that can prevent conception.
