Erection issues during copulation.

Hello We are planning for a baby since last 5 months. My husband has been having erectile dysfunction since last 2 years, for which he received ayurvedic treatment but it was no help. Despite this, we started planning, we had regular intercourse for 2 days during ovulation. Still, he has problem in getting a proper erection and maintaining it. i feel that semen is not spilled deep enough into vagina due to this reason. (my cycles are induced and monitored by follicular studies). Test shows that my husband's sperm count is pretty good as my gynae told me. My question is that can his erection issue effect our chances of conception? as semen doesnt go deep, is it possible that sperms are not able to reach fallopian tubes? pls guide.
