Dear
Welcome to HCM
We understand your concerns

I went through your details. Semen is supposed to smell like chlorine and bleach. Semen contains ammonia and other sterile-smelling alkaloids and this is the reason why it smells like your store-bough cleanser. However, your semen may smell differently on different occasions as well. The smell of your ejaculate may also vary depending on other factors such as your overall health and medications. Men also sometimes find that their semen tends to smell strongly when they haven’t ejaculated for a long time. It also seems to depend on the quantity of the semen released during an orgasm.

Poor personal hygene can result in foul smelling semen. The fish-like smell is an indication that a lot of smegma can be heaping up just under the penis head. Daily cleaning helps a lot.

Foul smells are usually associated with infections of the prostrate gland or other organs of the male reproductive system. If the smell is accompanied with a change in color of the ejaculate to red, brown, yellow or green, you definitely have an infection. It is time to consult a physician and get a diagnosis done.
