At your age with high prolactin we are concerned that a prolactin secreting pituitary adinoma is the cause and this does lower LH/FSH. A MRI is usually used to evaluate. Prolactin can get very much higher. One should not ignore these things as the adinomas can press on the optic nerves. Condition easily managed with 0.5mg/week Dostinex/cabergoline - so do not panic. Some medications can increase prolactin and recent orgasms or hugging babies/puppies/kittens can temporarily increase prolactin. There are other pituitary problems that can lower LH/FSH.
TSH=3.93 is normal because thyroid lab ranges are stupid at best. Should be closer to TSH=1.0
TSH may be high from iodine deficiency and that is easy in the UK because iodized salt is not generally on the shelves at the shops. fT4=13.9 should be mid-range 13.75 or a bit higher. So fT4 is good. But the active hormone is fT3 which has not been tested. fT4 is a reservoir for fT4–>T3 and T3 conversion may be impaired or perhaps rT3, reverse T3 is blocking effects of your fT3.
Thyroid affects your metabolic rate and thyroid hormones are used to regulate your body temperature and body temperatures are a measure of thyroid function that can be more useful than thyroid lab results. Please check your oral body temperatures twice a day as suggested later on in this post.
FSH is a better measure of your LH status than LH itself as serum LH levels vary greatly with a short half-life and pulsatile release.
Symptoms for years… was there a blow to the head or whiplash leading up to this?

Evaluate your overall thyroid function by checking oral body temperatures as per the thyroid basics sticky. Thyroid hormone fT3 is what gets the job done and it regulates mitochondrial activity, the source of ATP which is the universal currency of cellular energy. This is part of the body’s temperature control loop. This can get messed up if you are iodine deficient. In many countries, you need to be using iodized salt. Other countries add iodine to dairy or bread.

I can be a bit abrupt in my replies and recommendations. I have a lot of ground to cover as this forum has become much more active in the last two years. I can’t follow threads that go deep over time. You need to respond to all of my points and requests as soon as possible before you fall off of my radar. The worse problems are guys who ignore issues re thyroid, body temperatures, history of iodized salt. Please do not piss people off saying that lab results are normal, we need lab number and ranges.
The value that you get out of this process and forum depends on your effort and performance. The bulk of your learning is reading/studying the suggested stickies.
