Very fortunately it seems that sperm is gluten-free, I’m sure that is good news for everyone
Actually, fish sperm(milt) is quite delicious when cooked in a stew
@Kathy Maybe it's time to try some Asian cuisine? As you know, most of Asian diet consists of rice instead of wheat and there are many different ways to make a decent meal out of rice.
A good thing with rice is that it's pretty easy to store and cook. If you have a rice cooker, it's just a matter of put some rice and water into it and press the button then wait about half an hour to make steamed rice to last a day.
And there is even a pre-cooked variant which can be stored up to 9 months and consumed after microwaving it for a minute or two. I'm not sure if it's allowed to link to the Amazon page, so I won't mention it here. But if you feel interested, you can search "Cooked White Hetbahn, Gluten-Free & Vegan" on Google to see it.
Of course, you don't normally just eat rice for a meal. But there are a number of pretty easy recipes like fried rice or bibimbap, and you can also buy various pre-cooked packs which you can microwave with the above mentioned instant rice bowl and combine together to create a quick meal.
In case you love cooking, and interested in trying some exotic food based on rice, I think you may find some hints from this popular Youtube channel:

I'm sorry to hear that you have such a condition. And I hope you will soon find a way to manage the symptoms without too much trouble.
