I have noticed a bit of a pattern. Last month I didn't ejaculate for 5 weeks. Starting on the 4th week I noticed my stomach had started to growl a little between meals. This is massive for me as thanks to my gastroparesis and possibly low stomach acid, my stomach hasn't growled in years and I have to force food down me. My appetite significantly increased in this time. Then once I ejaculated a week later my stomach growling instantly disappeared and my appetite decreased (although it was still more than I'm used to). Tuesday I ejaculated after 4 days abstinence, in those 4 days my appetite was good, the day post ejaculation it was poor, and that night I was awoken by gastroparesis sickness feeling, of which I haven't had in months. It seems that abstaining from ejaculation is positively correlated with increased appetite/stomach growling. This makes me think that a nutrient/hormone used up in making sperm and used in making stomach acid is deficient in me. The obvious choice would be Zinc. It is used in great quantities in semen, and is also a cofactor for carbonic anhydrase which is used in the process of create stomach acid. 2 Slight doubts I have with this though is that I have taken zinc before (not for very long) and noticed no benefit, although it appears the benefit is soubtle / takes a while to build up. The other doubt is that I had a hair mineral analysis done years ago that had normal zinc whereas most other minerals where right on the deficient borderline (including copper). I can see this deficiency occurring through dysautonomia -> gastroparesis -> poor absorption -> low zinc -> low stomach acid -> low zinc absorption, vicious circle. I have started today taking a 3 year out of date zinc gluconate supplement twice per day @25mg. If it is not zinc, what else could cause this effect? Copper, low testostorone, low amino acids, high prolactin? What are common variables between semen and stomach acid that I'm missing? Anyone else had this experience? @nanonug Thanks.
