Firstly, which doctor did you consult?

If your ovaries are not releasing an egg every month, it means you are not ovulating. What surgery are you going to have? It could be that the doctor will be performing a key-hole surgery (laparoscopy) + tubal patency test (to see whether your fallopian tubes are patent or not). There is another alternative to this, which is HSG (hysterosalphingography) which doesn't involve surgery. Between these two options, the doctor usually will advise you on the best option based on your overall problem.

For abnormal semen results, another test is needed to make sure that the results are accurate.... In general, there are not many medical options available to improve sperm count unless there is a definite cause for the abnormality. Things your husband can do that MAY improve the counts are:
1) Stop smoking or drinking alcohol
2) Avoid hot baths + Wear loose underwear (sperm production is better at temperature below normal body temperature)
3) Lead a healthy lifesytle + ensure good control of any medical illness
4) Reduce stress

You should not avoid sexual intercourse just because you want to "save" up the sperm as that won't help. 2-3x a week is not excessive . Anyway, the best thing now is to wait for the 2nd semen analysis. In a lot of cases, the 2nd test may show good sperm count....
