Low male sexual function includes many aspects, mainly: 1. whether there is any abnormality in sexual desire, whether the penis can be erected under sexual stimulation, and whether the hardness of the erection is sufficient to insert into the vagina; 2. whether the erect penis can maintain sufficient hardness and time to complete sexual intercourse; 3. whether there is premature ejaculation, non-ejaculation, painful ejaculation, retrograde ejaculation, etc. Abnormalities in any of these links can lead to low male sexual function and disorders. And different treatments are taken according to different situations, as follows: 1. low libido: androgenic drugs can be applied to improve libido; 2. insufficient erectile hardness: PDE5 inhibitors can be used; 3. premature ejaculation: drugs such as dapoxetine or anesthetics can be used; 4. retrograde ejaculation occurs: it will directly affect fertility, so if you want to have children, you need to take assisted conception and collect semen.
