Reproductive System
The Reproductive System
Function is to produce life
Although the anatomic parts are different in male and female, they both have the same type of organs
Consists of gonads and accessory organs
Gonads are the sex glands (testes and ovaries)
Ducts (tubes) that carry the sex cells and the secretions
Accessory organs
Male
Testes
Gland that produce male sex cells (sperm) or spermatozoa in the seminiferous tubules that are in each testis and hormones like testosterone which helps the sperm mature and is responsible for secondary male sex characteristics -body and facial hair, muscles and deep voice
Scrotum
Sac suspended between the two thighs where the testes are housed
Scrotum is located outside of the body in order to have a lower temperature which is a must for sperm production
Epididymis
A tightly coiled tube that is approximately 20 feet long which the sperm go through after they develop in the seminferous tubules
It stores sperm until they mature and become motile and it produces fluid that become a part of semen
Vas deferens
A tube that goes up into the abdominal cavity and curves behind the bladder and joins with the seminal vesicle which receives sperm and fluid from the epididymis
It serves as a passageway and as a temporary storage area for sperm
Removed during a vasectomy
Seminal vesicles
2 small pouch like tubes that have a glandular lining that produces a thick yellow fluid rich in sugar that provides nutrients for the sperm and makes up a large part of semen
Ejaculatory ducts
2 short tubes that are formed from the union of the vas deferens and the seminal vesicles that carry sperm and fluids (collectively called semen) into the urethra
Prostate gland
A donut-shaped gland that produces an alkaline secretion that increases the sperm motility and neutralizes the acidity in the vagina
During ejaculation, the muscular tissue in the prostate gland contracts to help the expulsion of the semen into the urethra
Cowper’s glands
Glands located under the prostate secrete a mucus that serves as a lubricant for intercourse, and alkaline fluid which decreases the acidity of urine that resides in the urethra
The urethra carries both urine and semen
Penis
External male organ that is responsible for depositing semen in the vagina and the elimination of urine
Diseases and abnormal conditions
Epididymitis
Inflammation of the epididymis
Caused by gonococcus, strep, or staph
Frequently occurs with a UTI, or prostate infection, mumps or a STD
S/S intense pain in the testes, swelling and fever
If not treated can cause scarring and sterility
Treatment includes antibiotics, cold applications, scrotal support, and pain medication
Orchitis
An inflammation of the testes, usually caused by mumps, pathogens, or injury
S/S- swelling of the scrotum, pain, and fever
Lead to atrophy of the testes and cause sterility
Treatment- includes antibiotics, antipyretics, scrotal support, and pain medication
Prevention include mumps vaccinations and using measures to prevent STDs
Prostatic hypertrophy/hyperplasia
Enlargement of the prostate gland
S/S difficulty in starting to urinate, frequent urination, nocturia, dribbling, UTI, and urinary when the urethra is blocked
Treatment- fluid restriction, antibiotics, and prostatic massage, a prostatectomy, or a transurethral resection
Common in men over 50 and it can be benign caused by inflammation, a tumor, or a change in hormonal activity or a cancerous condition
Prostate cancer
Can have the same symptoms as prostatic hypertrophy or it may not have any symptoms
A screening (blood test) PSA can detect a substance released by the cancer cells and aid in early detection/dx
Digital exam may show a hard, abnormal mass in the prostate gland
Biopsy will diagnose it
If cancer, prostatectomy, radiation, and estrogen therapy (decreases testosterone) are main treatments
Testicular cancer
Cancer of the testes, usually occurs in men from 20 to 35.
Highly malignant and can spread rapidly
Treatment- orchiectomy (surgical removal of the testis), chemo, and radiation
Recommended start self exams at the age of 15
After a warm shower, using both hands, each testicle should be examined separately by placing the index finger under the testicle and the thumbs on top. The testicle should be gently rolled between fingers to feel for lumps, nodules, or extreme tenderness. Look for signs of swelling or any change in appearance
S/S painless swelling of the testes, a heavy feeling, and an accumulation of fluid
Female
Ovaries
Female gonads, small and almond shaped and are attached to the uterus by ligaments
Contains thousands of small sacs called follicles with each follicle containing an immature ovum (female sex cell)
When an ovum matures, the follicle enlarges and then ruptures to release the mature ovum (process called ovulation)
Occurs usually every 28 days
Ovaries also produce hormones that help in the development of the reproductive organs and give rise to the secondary sexual characteristics
Fallopian tubes
Two tubes that are 5 inches long and attached to the upper part of the uterus, the ends (lateral) are above the ovaries but are not connected to them
Serves as a passageway to the uterus for the ovum and is where fertilization takes place
The ends have fingerlike projections (fimbriae) which helps move the ovum
Uterus
Hollow, pear-shaped muscular organ
Divided into three sections
Corpus
The body or middle section
Cervix
Narrow bottom section which attaches to the vagina
Fundus
The top portion
Organ of menstruation, allows the development and growth of the fetus, and contracts to aid in the expulsion of the fetus during birth
Three layers:
Endometrium
Inner layer of specialized epithelium which provides for implantation of the fertilized ovum and helps aid in the development of the growing fetus
If fertilization does not occur, the endometrium deteriorates and causes bleeding (menstruation)
Myometrium
The muscular middle layer
Allows for the expansion of the uterus during pregnancy and contracts to expel baby
Perimetrium
Outer layer made of serous membrane
Vagina
Muscular tube that connects the cervix of the uterus to the outside of the body
Lines with a mucous membrane a with rugae (folds) that allows the vagina to expand for childbirth and intercourse
Serves as a passageway for the menses, receives sperm, and semen from the males, and is the organ of copulation and acts as a birth canal
Bartholin’s glands (vestibular glands)
Glands located on each side of the vaginal opening that secrete mucus for lubrication for intercourse
Vulva
Collective name for the external genital area
Labia majora
Two large folds of fatty tissue that enclose and protect the vagina
Labia minora
Two smaller hairless folds behind the labia majora
Mons veneris (mons pubis)
Triangular pad of fat covered with hair
Breasts or mammary glands
Contain lobes that are separated into sections by connective tissue and fatty tissue
Milk ducts located in the tissue
The main function of the glands is to secrete milk (lactate) after childbirth
Diseases and abnormal conditions
Breast tumors can be benign or malignant
S/S lump or a mass, a change in size or shape, discharge from the nipple
BSE recommended once a month
Examined in front of a mirror to look for changes in appearance, in a warm shower after soaping, and while laying down in supine position
CBE is recommended q3 years for women in their 20s and 30s and q year starting at 40
Mammograms and US can detect tumors up to two years before they are felt
Treatment lumpectomy, simple mastectomy, or a radical mastectomy (removal of breast tissue, underlying muscles, and axillary lymph nodes)
If cancerous chemo and radiation
Cancer of the cervix and/or uterus is common and can be detected by a pap smear
Most common cause is HPV
S/S abnormal vaginal discharge and bleeding
S/S of uterus enlarges uterus, a watery discharge, and abnormal bleeding
Treatment- hysterectomy (uterus and cervix), or a panhysterectomy, chemo, radiation
Vaccine to prevent infection caused by HPV
Endometriosis
Abnormal growth of the endometrial tissue outside the uterus
Treatment- differ with age, pain medications and or surgery
S/S pelvic pain, abnormal bleeding, and dysmenorrhea
Causes sterility if fallopian tubes become blocked
Ovarian cancer
One of the most common causes of cancer death in women
S/S vague discomfort in abdominal region, mild GI disturbances like constipation and or diarrhea, abdominal distention, and urianary frequency (3/4 of cases go undetected until it metastasized to abdomen)
Treatment- surgical removal of all the reproductive organs, and affected lymph nodes, chemo, and radiation
Frequently occurs in ages 40-65
Pelvic inflammatory disease (PID)
Inflammation of the cervix, the endometrium, fallopian tubes, and at times the ovaries
S/S pain in the lower abdomen, fever, and a purulent(pus) drainage (vaginal)
Treatment- antibiotics, increased fluid intake, rest, and or pain medication
Caused by bacteria from a sexually transmitted infection, viruses, and fungi
Premenstrual syndrome (PMS)
A group of symptoms that appear 3-14 days prior to menstruation
S/S nervousness, irritability, depression, HA, edema, backache, constipation, abdominal bloating, food cravings, temporary weight gain and breast tenderness and enlargement
Treatment is relieving symptoms and methods include, diet modifications, exercise, massage, light therapy, stress reduction, diuretics and analgesics
Usually peak in late 20s and early 30s, cause is unknown but may be related to hormonal or biochemical imbalance, poor nutrition, or stress
Sexually Transmitted Diseases (STDs)
Acquired Immune Deficiency Syndrome (AIDS)
Caused by human immunodeficiency virus (HIV), this virus attacks the immune system so that it is unable to fight off infections and diseases which eventually causes death
It can spread through sexual secretions or blood and from an infected mother to her infant during pregnancy or childbirth
Can remain free of symptoms for years but can still spread the virus
After initial asymptomatic period individuals develop early symptomatic HIV infection, called Class B (formally known as Aids-related complex or ARC)
S/S +blood test, lack of infection resistance, appetite loss, weight loss, recurrent fever, night sweats, skin rashes, diarrhea, fatigue and swollen lymph nodes
When WBC level drops below 200cells /cubic millimeter opportunistic diseases occur (pneumocystis jiroveci, Candidiasis, and Karposi’s Sarcoma
Tx- No cure, trying to develop a vaccine. Take a drug cocktail (no cure) Prevention best method, should avoid multiple sex partners, not share needles for drug users, a condom and effective spermicide should be used to form a protective barrier during
Chalmydia
One of the most frequent occurring STDs and is caused by several strains of chlamydia organism
Can be spread from mother to baby during childbirth, and can cause severe eye infections or pneumonia
S/S (similar to gonorrhea) Males will have burning when urinating, and a mucoid discharge. Females frequently are asymptomatic, although some will have a discharge
This infection can cause PID and sterility in women if not treated
Can be treated with antibiotics
Gonorrhea
Frequently called “the clap” is caused by gonococcus bacterium Neisseria gonorrhoeae.
S/S males have a greenish yellowish discharge, burning when urinating, sore throat, and swollen glands. Females, are usually asymptomatic but may experience dysuria, pain in the lower abdomen, and greenish -yellow vaginal discharge
Tx with large doses of antibiotics
Infected moms can pass on to their babies and it can affect eyes causing blindness. To prevent this a drop of silver nitrate or antibiotic is routinely placed in the eyes of newborns
Herpes
A viral infection caused by the herpes simplex virus type II
S/S burning sensation, fluid filled vesicles that rupture and form painful ulcers and painful urination
After sores heal, the virus lays dormant. (Can spread still) Repeated attacks, but those attacks can be milder
No cure
Tx pain management and antiviral medication
Pubic Lice
Parasites that are usually transmitted sexually and can spread by contact with clothing, bed linen, or other items that contain lice
S/S intense itching and redness of the perineal area or to other ares that have hair like armpits, eyelashes
Topical lotions or creams are used to kill lice
Syphilis
Caused by the spirochete bacterium
S/S occur in stages
Stage I- a painless chancre or sores appear on penis or vulva or cervix chancre heals within several weeks
Stage II- if stage I is not treated, the organism enters the bloodstream and causes a rash that does not itch, a sore throat, fever, HA, malaise and swollen glands
Stage III- years later, damage to heart and blood vessels, gait and paralysis, brain damage causes mental disorders, deafness and blindness damage is irreversible and death occurs
Early diagnosis treat with antibiotics and can cure the first two stages
Trichomonas vaginalis
Caused by the parasitic protozoan trichomonas vaginalis
S/S large amount of frothy, yellow green, foul smelling, discharge. Men may experience urethral itching
Sometimes (rare) may expel the parasite without treatment, otherwise Flagyl is used to treat. Both partners must be treated
