Has you doctor done all other tests to find out why you are not conceiving?
Considering that your tubes are patent has you doctor tested your partners semen sample?
If all other tests (which include a lot of blood tests and sonography
) are normal then probably laparoscopy
is the only way to find out why you are not able to conceive.
however before you go under the table I would suggest take a second opinion
from another gynecologist just to be on the safer side.
If then the opinion is same you can go ahead with the laparoscopy.
