Hi Bobody
There are lots of threads on tesosterone so you will get more info as well as the responses here by going to the forum home page and doing a search.
However I started a now long-running one in Private Lives here:
https://www.menopausematters.co.uk/forum/index.php/topic,27959.0.htmlAlso one on dosages here:
https://www.menopausematters.co.uk/forum/index.php/topic,39588.msg666825.html#msg666825Re your question.
At this point personally I would not see the necessity for replacement testosterone - the blood tests are inaccurate for women at low levels and some gynaes don't do them. From what you say about your menopausal status you are not yet officially in peri-menopause yet as your periods are pretty regular and close together. The stage you are in is medically known as the Late Reproductive Stage (or Phase). Many women start to get symptoms at this point because hormones start to go awry, and especially in many women PMS starts to worsen. HRT can be hit and miss at this stage though - from reading on here - for some women it is the magic that works, for others it causes more problems.
Oestrogen deficiency and a whole host of other causes can be a reason for joint pain so I wouldn't be in a hurry to start it (T) for this symptom and it is not clinically indicated anyway for this alone. Reduced libido would be the first thing to occur and persist, long before other symptoms of low T are felt - I would say. eg I started it (T) when I was probably 6 or 7 years post-meno - but would probably have benefitted a year or two ealrier. Libido went awol years before!
Personally I would park it somewhere in your mind for future reference but concentrate on getting well after your op and starting a low dose oestrogen until you feel well - and then forget about it until ( if) other symptoms appear and persisit.
I know some private gynaes seem very keen on replacing it straight away, but not sure about the evidence - there is so little research and we need more!
Hope this helps
