what i understood has nothing to do with age or training but with the use of magic itself as they use their bodies to channel the power they absorve from the sources (water/earth/fire/wind), their infertility is a side effect. One evidence of that is when Yen is training Ciri, the girl complains that her lower stomach hurts when she is absorving the magic. In Ciri's training, when she is learning about absorving the sources her nose starts to bleed and Yen warns her about draining the power from the sources too fast because it can be letal. So it cleary shows how magic affects their bodies, so much than in long term it results in infertility.

So for Visenna either she was a younger sorceress or her body somehow reacted diferently to the magic
