Final answer:
The combining form 'prostat/o' refers to the 'prostate gland', a key part of the male reproductive system responsible for secreting seminal fluid components during ejaculation.
Step-by-step explanation:
The CF (combining form) prostat/o refers to the prostate gland. This gland is a critical part of the male reproductive system and is located at the base of the bladder, surrounding the urethra. It is responsible for producing a significant portion of the seminal fluid during ejaculation, which includes substances like zinc, citrate, enzymes, and prostate specific antigen (PSA). The prostate gland's secretion plays a key role in both the coagulation and decoagulation of semen after ejaculation. This function is crucial for maintaining the viability of sperm within the female reproductive tract post-ejaculation.
