"In general, the direct actions of melatonin on the gonads and adnexa of mammals indicate it is an important agent for maintaining optimal reproductive physiology" - https://www.mdpi.com/1422-0067/14/4/7231 https://www.mdpi.com/1422-0067/14/4/7231 When I look at other papers in this space I do find some adverse responses in hamster nuts when given melatonin injections (but not when it is administered using an implant). At this point I did not want to research the other claims in the quote anymore. Instead, perhaps I can ask you: Do you know of any solid research that backs these (frankly very strong and contrary to everything else I've read) claims? If not, why did you choose to say this?
