Can Subclinical hypothyroidism lead to infertility?

I was diagnosed with subclinical hypothyroidism early this year as my TSH has been bouncing between 8.7 (highest) and 3.4 (lowest) over the last two years. Last bloodwork showed TSH of 6.3. I am not being treated, doctors still have the „wait and see approach“ as TSH is not high enough. I have antibodies which indicate I have Hashimoto.

I have symptoms, but not sure if they are all typical for hypothyroidism - fatigue, muscle pain, hair thinning, trouble sleeping (my body felt like it’s on fire at night, started to get better since I’m taking vitamin d), trouble concentrating. This had been going on for much longer than the two years I’ve been monitored for thyroid levels. I haven’t gained any weight and I’m skinny (1,62cm / 53kg). I have zero sex drive and don’t really feel like myself overall. My cycle is all over the place. Digestion is all over the place. All my symptoms are not keeping me from being active and living a normal life, and I guess I don’t know anything else so for a long time I didn’t realize something is wrong.

I had my hormone levels checked by a naturopath and my FSH and LH are in tue range of postmenopausal women. It was quite a shock and I’m wondering if my untreated subclinical hypothyroidism could have led to this? Should I start taking meds?

Thanks so much for your help, I’m just starting to understand it all better. I’ve read lots of posts on here and it seems such an incredibly complex condition I feel a bit overwhelmed.
