He I've been through this myself and I'm a physician- I think this is a great idea! I think every woman who thinks she might want to become a mother and is older than 30 should do this to get a sense of where she stands. I know I was shocked when at age 33 I was told I had the eggs of a woman 10 years older!

Here is my advice: when they do a day 3 bloodwork they will probably do what is called an FSH level - FSH stands for follicle stimulating hormone, and starts to go up as the remaining number and quality of our eggs decreases. The problem is it's an old test, and doesn't start to rise until pretty late in the game, like when you're approaching menopause. What you want them to do is the new test, called AMH or antimullerian hormone. It's much better at picking up early drops in egg quality and reserve.

I say this as someone who had a normal FSH, could not get pregnant, and when I finally went to fertility clinic was told my AMH was so poor I'd need donor eggs. Luckily after 4 rounds of ivf I'm now pregnant with my miracle baby, but I'm determined not to let this happen to anyone else. Bottom line: ask for AMH test!

I'm in the same process. I am looking to do the IVF before the end of the year, though. The testing hasn't been too much. There is a possibility, if you are 35 and older (like me), you will have to a maternal fetal medicine, depending on your timeline.
Your dh will need to be tested as well. His testing is easier than yours, but some guys, mine included, don't like doctors.

If you have specific questions, let me know in a private message. It's still fresh in my mind, since I did it this month.

It took my DH and I two years to conceive the twins I'm carrying. I'll be 33 in May and he'll be 32 in November. We went through all of those tests and everything came back normal. My DH got a super good report back on his sperm as well. We were diagnosed with the dreaded "unexplained infertility" and in our case secondary unexplained infertility bc we both have children already. I think the tests are definitely a good idea, if they find any issues at least you will know what you're up against.

Didn't go through it myself but during my acupuncture internship, I saw several patients who did the tests and then began actual fertility treatments when the tests came back poor. (Fertility clinics often pair up with acupuncturists because there are some studies that suggest acupuncture used in tandem with IVF can increase chances of success.) They measure hormone levels (the rise and fall during your cycle to check if it's correct.) The ultrasound is to check how your follicles are developing. Your body usually starts developing anywhere from 8 - 12 follicles and then one of them becomes the dominant one to be released while the rest die. Some women either don't develop enough or develop too little, regardless of how much medication to increase it they take. They also check FSH (follicle stimulating hormone) levels--too much of it means your body is pumping the hormone in to try and stimulate follicle growth but it's not getting any success so it keeps pumping more and more in. This is probably one of the worse scenarios because it means the ovaries likely have no more eggs and you're hitting menopause (one of my patients had this.)

Then there's also issues with progesterone level after conception to keep a pregnancy--if someone has too low of that hormone, the egg will be fertilized but the pregnancy won't keep so it's something they will monitor to see if you will need a boost after fertilization.
