The physiological responses of the epaulette shark to low oxygen are mediated by the nucleoside adenosine . In hypoxic conditions, the heart and ventilation rates drop sharply.  The shark's blood pressure falls by half as the blood vessels dilate to deliver more blood to the brain and heart. Unlike in bony fishes and tetrapods, the blood flow rate remains constant and there is no elevation of blood glucose levels.  The brains of sharks only consume a third as much ATP as those of teleosts .  The epaulette shark is able to lower this energy demand further by reducing the metabolism of certain areas of its brain, . keeping the sensory nuclei functional while deactivating the motor nuclei. This allows the shark to supply enough ATP to prevent neuron death, while still remaining alert to its environment. 
Again, a great question for your doctor!! Discuss this with them. One very good option is always simply not to do it. You are the best one to weigh the pros and cons that your doctor lays out for you and decide what is the right decision for you. One thing that people often fail to realize is that the normal range for testosterone is that – a NORMAL RANGE. That means that readings anywhere in that range are NORMAL. If you are on the “low side of normal” – that is NORMAL. Another thing to realize is that doctors to not treat test results, they treat symptoms. Just because your testosterone comes in at 200 does not necessarily mean you need TRT! See also the below question.
Is it possible for PF muscles to ever fix themselves in relation to us fixing poor habits? For a while after my son was born, whenever I would stand for long periods of time, it felt like all the blood was rushing down to my perineum, and I would have this painful burning sensation in my lower back. I hadn’t found this gem of a site at that point, and was probably doing 100+ kegels daily, trying to be diligent and stay tuned. *hah* After finding this site, squatting, walking 4+ miles daily, and giving up on kegels, (My apologies to the queen!) I no longer experience that pain. I always thought it was just time more fully healing my body, but could these changes have been my body self correcting as I learn better habits?
