Hello. I am 33 Years old male. I have MVP/MR of mild to moderate grade. I am taking Aspirin 75mg for the last two years. I measure my BP and PR almost daily. My BP is normal but my pulse rate are always more than 100. Further, for the last 6 months I have completely lost my sexual desire. I don't know whether tachycardia is because of MVP/MR or there is some other problem related to sexual disorder. Should I check my cortisol level to measure stress level? As such, I don't have any mental depression. But I doubt the stress level which may cause higher pulse rate and loss of libido. I have undergone other tests like CBC, Thyroid, Ferritin, Calcium, Prolactin and B12. But all these are normal. I am confused how to go further. I have consulted physicians but they have not been able to find out the exact cause.
