Reproductive Function Flashcards
The generation of sperm
Spermatogenesis
Part of the male external genitalia; it contains erectile tissue that fills with blood during sexual arousal
Penis
A sheath of loose skin that covers the glans penis at birth. Often surgically removed for hygienic, cultural, or religious reasons
Foreskin
An oily secretion produced by the glans that can combine with dead skin to form a cheesy substance. If not regularly removed from under the foreskin, the penis can become irritated and infected
Smegma
An opening or passageway
Meatus
Propulsion of sperm-containing fluid
Ejaculation
A sac of skin just below the penis that contains the testes, epididymis, and lower spermatic cords
Scrotum
Gonads; organs that produce sperm and the sex hormones
Testes
Structure in the male reproductive tract that stores sperm up to 6 weeks until ejaculation
Epididymis
Hormone that gives males their classic secondary sex characteristics and sex drive. Can also regulate metabolism and protein anabolism, inhibits pituitary secretion of the gonadotropins, and promotes potassium excretion and renal sodium reabsorption
Testosterone
Part of the male duct system that carries sperm out of the testes
Vas deferens
A cordlike structure, consisting of the vas deferens and its accompanying arteries, veins, nerves, and lymphatic vessels, that passes from the abdominal cavity through the inguinal canal down into the scrotum to the back of the testicle
Spermatic cord
A pouch that joins the seminal vesicles to form the ejaculatory duct in the male reproductive system. Stores semen and contributes secretions to it
Ampulla
A pair of pouches that secrete an alkaline ejaculatory fluid containing sugar, protein, and prostaglandins. Join with the ampulla to form the ejaculatory duct
Seminal vesicles
Canal in the male reproductive tract formed by union of the vas deferens and the duct from the seminal vesicle
Ejaculatory duct
Fluid made up of ejaculatory fluid and sperm. It flows from the ejaculatory duct to the urethra, where it is released from the penis during sexual intercourse
Semen
A chestnut-shaped gland at the base of the urethra in men; it produces fluid that mixes with the sperm and secretions of the seminal vesicles. This fluid decreases acidity of the secretions, increases sperm motility, and prolongs sperm life
Prostate gland
Two pea-sized glands adjacent to the urethra that secrete an alkaline fluid into the urethra to neutralize acidity caused by urine transportation. These secretions can sometimes be seen at the meatus before ejaculation. This secretion aids in lubrication of the penis during sexual intercourse and may contain some sperm left over from a previous ejaculation
Cowper gland
The climax of pleasurable sensations
Orgasm
The generation of eggs
Oogenesis
The transportation of the eggs
Ovulation
The fertilization of eggs
Impregnation
The support of fetal development from conception to birth by the female reproductive system
Gestation
The birth of the fetus
Parturition
The production and secretion of milk for the feeding of offspring
Lactation
Paired almond-shaped organs located on each side of the uterus
Ovaries
Two cylinders that extend from the fundus of the uterus to the ovaries
Fallopian tubes
A fertilized egg
Zygote
Pregnancy in which the zygote does not reach the uterus but rather implants outside the uterus
Ectopic pregnancy
A hollow pear-shaped organ held in place by the broad, round uterosacral ligaments
Uterus
Tilted forward. Usually used in reference to the uterus
Anteflexed
Tilted backwards - in reference to the uterus
Retroflexed
The inner mucosal lining of the uterus wall that undergoes hormonal changes to facilitate and maintain pregnancy
Endometrium
A vascular organ that develops during pregnancy to nourish the fetus through the umbilical cord
Placenta
The middle layer of the uterine wall, made up of smooth muscle and a vascular system. During pregnancy, the vascular system radically increases to support the fetus
Myometrium
The outer serous layer of the uterine wall that covers all of the fundus and part of the corpus but none of the cervix
Perimetrium
The narrow opening from the vagina to the uterus
Cervix
A series of monthly changes in females that begin at puberty and continue through the reproductive years
Menstrual cycle
Shedding of the endometrium. It generally occurs on a regular basis (usually every 28 days) during the reproductive years of women.
Menstruation
The complete and permanent cessation of the menstrual cycle
Menopause
A hollow tunnel-like structure that extends from the cervix to the external genitalia
Vagina
Gland in the mucosal lining of the vagina that secretes a protective lubricating fluid during sexual intercourse
Skene gland
A thin connective tissue that covers the external vagina opening to some degree
Hymen
The structures of external female genitalia. These structures include the mons pubis, the labia majora, the labia minora, the clitoris, and the vestibule
Vulva
The pad of fat over the symphysis pubis that becomes covered with hair after puberty
Mons pubis
The two large, fatty skin folds of the external genitalia that protect the perineum and aid in lubrication
Labia majora
Two small, firm skin folds located just inside the labia majora of the external female genitalia
Labia minora
Part of the vulva formed by the connection of two labia minor. It’s sensitive to stimulation and becomes filled with blood during sexual arousal. It contains two corpora cavernosa, similar to the penis
Clitoris
Glands that lie just within the labia minor and provide lubrication during sexual intercourse
Bartholin glands
The area of the vagina that contains the urethral and vaginal opening
Vestibule
Glands that are located in the breast of male and female but function only in females. They produce milk when stimulated to do so
Mammary glands
A hormone from the anterior pituitary gland that stimulates milk production
Prolactin
A pigmented projection of the breast that is surrounded by the areola
Nipple
An area of pigmentation surrounding the nipple of the breast
Areola
Gland that produces secretions that protect and lubricate the nipple and areola of the breast during breastfeeding
Areolar gland
The urethral meatus occurring on the dorsal surface of the penis instead of the end
Epispadias
Condition in which the urethral meatus is found on the ventral surface of the penis instead of the distal end
Hypospadias
A downward curvature of the penis
Chordee
A congenital condition in which one or both testes do not descend from the abdomen to the scrotum prior to birth
Cryptorchidism
Undescended testes that deviate from the path of descent
Ectopic testes
A testicle that moves back and forth between the scrotum and the lower abdomen. Such a testicle is easily returned to the scrotum through gentle manipulation
Retractile testicle
A testicle that has returned to the lower abdomen and cannot easily be guided back into the scrotum. Also called acquired undescended testicle
Ascending testicle
A biological inability to contribute to reproduction
Infertility
The inability to attain or maintain a penile erection sufficient to complete sexual intercourse. Also called impotence

Painful menstruation, to the extent that it impairs daily activities
Dysmenorrhea
A group of physical and emotional symptoms that affect many women prior to menstruation for reasons not fully understood
Premenstrual syndrome (PMS)
A severe form of premenstrual syndrome that is characterized by severe depression, tension, and irritability
Premenstrual dysphoric syndrome
Condition that occurs when the bladder protrudes into the anterior wall of the vagina
Cystocele
Condition that occurs when the rectum protrudes through the posterior wall of the vagina
Rectocele
The descent of the uterus or cervix into the vagina
Uterine prolapse
Condition in which the endometrium begins growing in areas outside the uterus
Endometriosis
