The human male reproductive system indeed has accessory sex glands. These include:

A) Seminal vesicles: These are a pair of simple tubular glands posteroinferior to the urinary bladder of male individuals. They secrete a significant proportion of the fluid that ultimately becomes semen.

B) Prostate gland: This is a gland surrounding the neck of the bladder in male mammals and releasing prostatic fluid.

C) Cowper’s glands: Also known as bulbourethral glands, they produce a clear, slippery fluid that empties directly into the urethra. This fluid serves to lubricate the urethra and to neutralize any acidity that may be present due to residual drops of urine in the urethra.

So, the answer is D) All three.
