For guys, no limit.
For ladies, the older u r, the more difficult it is to get pregnant. Higher risk of down syndrome babies with older ladies. Older age, higher risk during pregnancy
For guys no limit correct, but younger males have a higher spermcount.
The female is clearly the biggest factor for your chance to conceive, but if you have a older woman + younger male it does compensate a little bit at least.
For females generally speaking untill 30 it's easy to conceive, 30-35 it's a bit harder, 35-40 it's very hard, 40-45 best chance is IVF .
Also important to note if a female was pregnant before it slows down the age factor. So if a woman has a child at 28 for example and at 44 deciddes I want another child ! it's more likely for that woman to conceive than for a first time mother. This explains why sometimes married couples have "accidental " younger children compared to the rest of their children.
