We'd like to conceive, we are and we live both healthy, but my husband had a bit too much drinks about 2 months ago. could this have any influence if we might conceive now, since sperm take about 2/3 months to produce?

Men get a break with their lifestyle choices more than women when it comes to reproduction. Only the healthier sperm swim well so any affected by a drinking bout are less likely to be successful. There are millions produced continuously and this differs from the woman whose one egg is released after whatever her exposures have been. I wouldn't make much of his habits, but help him do better.

No - that had no affect on sperms
