go ahead and see if they can do the laparoscopy. i've had 3 done, and they are pretty easy to recover from. it will give you some answers too.
we didn't do in vitro fertilization (ivf) because i have a sucky uterine environment. also, we couldn't agree for a few years about it (i wanted to, he didn't; then we ended up spending the money we had for it on car repairs! yikes!). for us, it would have been around 10,000.00 including fertility drugs (not covered by insurance), sonograms (although my ob/gyn said he'd do the sonos for free as a gift- would save us about 1500.00 because they're done every other day, sometimes every day), bloodwork (done each time you have a sonogram), egg retrieval including hospitalization and anesthesia, embroyologist, lab, embryo transfer. if we wanted to do ICSI (intracytoplastic sperm injection) or assisted hatching, it would cost extra.
but i have problems when i use fertility drugs and am terrified to try them again. and now we're just getting too tired of it all.
i understand your feelings completely about seeing all your friends and family getting pregnant and leaving you behind. we are now the last couple without kids even at our workplaces. and it's sometimes hard. but we do have a lot more freedom than our friends. and i feel our marriage is better and stronger. we tried almost 10 years, and it's time to let go. but it's hard somedays.
try to focus on the positives when you start to feel down. it does help. i have one friend who has toddlers, and she calls me sometimes when the kids are fighting, biting or screaming to remind me to enjoy my peace and quiet. lol. it does help me remember that life is still good even though i can't have kids.
