Ejaculation is generally defined as the expulsion of sperm through the urethra, and since the testes are the main organ that produces sperm, if a man does not have testes bilaterally, ejaculation is usually not accomplished. The testicles are the male reproductive organs where sperm is produced. If a man does not have a testicle on one side, it usually has no effect on the man’s sexual function because the remaining testicle can produce enough androgens and sperm to have normal sex and reproduce. If both testicles are absent, it will affect the secretion of male hormones and sperm production, resulting in a large amount of androgen deficiency in the body, which will lead to loss of libido and inability to have an erection. Therefore, men without testicles are usually unable to have sex and ejaculate, and will lose the ability to procreate, etc. It is recommended to have a doctor’s examination in time to determine the cause of the disease. It is recommended that the patient should consult a doctor for examination in time, so as to clarify the condition and then carry out targeted treatment.
