Yes, you can have an orgasm without ejaculating. This is called having a dry orgasm, or orgasmic anejaculation. Dry orgasms can have numerous causes, some of which are only temporary, but some can be either last a very long time, or even be permanent. The causes of dry orgasms include: Multiple or repeated orgasms - this can cause your body's semen stores to get depleted, meaning less or none is released the next time you orgasm Testosterone deficiency - this can happen to people who have a hormone imbalance, and also can occur with age Damage to nerves - this can be a result of injuries to the spine, or as a side effect of illnesses like cancer, diabetes, and multiple sclerosis Blockages in the urethra or the ejaculatory duct - this can be caused by growths such as cysts, or even trapped sperm Genetic abnormalities - your genes may mean you simply don't produce enough semen and don't necessarily have a health issue Certain surgeries - various kinds of surgery can affect the nerves and muscles that allow you to ejaculate semen, such as having your bladder, lymph nodes, or prostate removed. In some cases, what can appear to be a dry orgasm can actually be what is known as retrograde ejaculation, which is when semen goes backwards into your bladder as opposed to coming out of your penis. This can happen if your bladder doesn't remain closed when you orgasm - meaning semen is allowed in, and is released later on in urine. Retrograde ejaculation, and dry orgasms in general, aren't necessarily a big problem unless you want to have children. If you have any concerns about dry orgasms, visiting a healthcare professional like a doctor can help find the cause, and if applicable, can help treat the issue.
