Chastity and orgasm denial discussion

I’m just starting out here, and I joined partly because I worry about how chastity might affect fertility. My spouse and I have been trying to conceive for nearly three years now without success. Recently, we’ve started wondering if his being kept in a cage has any impact on his sperm health (he isn’t locked up for more than a week at a time usually, so that duration itself isn’t the problem). He feels he shouldn’t be confined while we are trying to conceive. I get his logic and am frustrated by how long this process takes, but I really miss having him locked! I know this forum doesn’t give medical advice, but I’d love to hear what other couples have experienced regarding fertility when using cages periodically. Could being locked up actually help? Since it prevents ejaculation, maybe it allows sperm count to build up? His semen tests showed low count, morphology, and motility. Or could the constriction and slight pull on his testicles be harmful? Many fertility sites recommend men switch from briefs to boxers because briefs keep things warmer by holding them closer to the body. This makes me think confinement might be detrimental. Any suggestions for enjoyable alternatives while he is unlocked? Teasing and denial just don’t feel right without him being caged. I’ve read through older threads and it seems this topic has come up before, though not recently.
