Penis (M - external sex organs)
the male organ of sexual intercourse
Corpora cavernosa (the penis)
cylinders of spongy tissue in the penis that become congested with blood and stiffen during sexual arousal
Corpus spongiosum (the penis)
the spongy body that runs along the bottom of the penis, contains the penile urethra, and enlarges at the tip of the penis to form the glans

Foreskin (the penis)
the loose skin that covers the penile glans. Also referred to as the prepuce
Surgical removal of the foreskin of the penis
an abnormal condition in which the foreskin is so tight that it cannot be withdrawn from the glans
Scrotum (M-external sex organs)
the pouch of loose skin that contains the testes (from the same linguistic root as the word shred, which means "a long, narrow strip" probably referring to the long furrows on the scrotal sac)
the cord that suspends a testicle within the scrotum and contains a vas deferens, blood vessels, nerves, and the cremaster muscle
a tube that conducts sperm from the testicle to the ejaculatory duct of the penis.
Cremaster muscle (the scrotum)
the muscle that raises and lowers the testicle in response to temperature changes and sexual stimulation.
Germ cell (M-internal sex organs)
a cell from which a new organism develops
the male germ cell
Male sex hormones
a male steroid sex hormone
Seminiferous tubules (M-internal sex organs)
tiny, winding, sperm-producing tubes that are located within the lobes of the testes
the process by which sperm cells are produced and developed
Epididymis (M-internal sex organs)
a tube that lies against the back wall of each testicle and serves as a storage facility for sperm.
a sterilization operation in which the vas deferens are severed
Seminal vesicles (M-internal sex organs)
small glands that lie behind the bladder and secrete fluids that combine with sperm in the ejaculatory ducts.
Ejeaculatory duct (M-internal sex organs)
a duct, formed by the convergence of a vas deferens with a seminal vesicle, through which sperm pass through the prostate and gland and into the urethra.
Prostate gland (M-internal sex organs)
the gland that lies beneath the bladder and secretes prostatic fluid, which gives semen its characteristic odour and texture
Cowper's glands (M-internal sex organs)
structures that lie below the prostate and empty their secretions into the urethra during sexual arousal
the whitish fluid that constitutes the ejaculate, consisting of sperm and secretions from the seminal vesicles, prostate gland, and Cowper's glands
a physician who specializes in the diagnosis and treatment of diseases of the urogenital system
An inflammation of the bladder or urethra
a condition in which one or both tesitlces fail to descend from the abdomen into the scrotum.
Benign prostatic hyperplasia
enlargement of the prostate gland due to hormonal changes associated with aging and characterized by symptoms such as urinary frequency, urinary urgency, and difficulty starting the flow of urine.
Inflammation of the prostate gland
the enlargement and stiffening of the penis as a consequence of its engorgement with blood
Performance anxiety (M - sexual functions)
feelings of dread and foreboding experienced in connection with sexual activity (or any other activity that might be judged by another person)
Sacrum (M-sexual functions)
the thick, triangular bone located near the bottom of the spinal column
Autonomic nervous system
the division of the nervous system that regulates automatic bodily processes, such as heartbeat, pupil dilation, respiration, and digestion. (ANS)
Sympathetic (role of autonomic nervous system)
the branch of the ANS most active during emotional responses that draw on the body's reserves of energy, such as fear and anxiety. The sympathetic ANS largely controls ejaculation.
Parasympathetic (the role of the ANS)
the branch of the ANS most active during processes that restore the body's reserves of energy, such as digestion. The parasympathetic ANS largely controls erection.
a sexual dysfunction in which the male persistently ejaculates too early to afford the couple adequate sexual gratification.
an abnormal condition characterized by an excessive curvature of the penis that can make erections painful
the climax of sexual excitement
a person with sensory and motor paralysis of the lower half of the body
Emission stage (ejaculation)
the first phase of ejaculation, which involves contractions of the prostate gland, the seminal vesicles, and the upper part of the vas deferens
a sac or dilated part of a tube or canal
Urethral bulb (ejaculation)
the small tube that makes up the prostatic part of the urethral tract and that balloons out as muscles close at either end, trapping semen prior to ejaculation.
Expulsion state (ejaculation)
the second stage of ejaculation, during which muscles at the base of the penis and elsewhere contract rhythmically, forcefully expelling semen and generally providing pleasurable sensations.
ejaculation in which the ejaculate empties into the bladder.
