  36. Parenchyma
    Functional, essential tissue of an organ. The seminiferous tubules are the parenchyma of the testis.
  37. Perineum
    In a male, the external area between the anus and scrotum. In a female, the external area between the anus and the vagina.
  38. Phimosis
    Narrowing (stricture) of the opening of the prepuce (foreskin) over the glans penis.
  39. Photoselective vaporization of the prostate

  40. Prepuce
    Fold of skin covering the glans penis (tip of the penis); foreskin.
  41. Prostatectomy
    Removal (excision) of the prostate gland.
  42. Prostate gland
    Exocrine gland, in men, at the base of the urinary bladder. It secretes fluid (part of semen) into the urethra during ejaculation.
  43. Prostatic hyperplasia
    Increased growth of the prostate gland in numbers of cells. This is a hyperplasia benign condition (benign prostatic hyperplasia or BPH).
  44. Prostatitis
    Inflammation of the prostate gland.
