Reproductive system Kirsten Berg P.5
Major functions of the Reproductive system
Male
to produce maintain and transport sperm to the vagina
producing male sex hormones
Female
Produce and maintain sex cells (egg cells, oocytes)
Transport these cells to the site of fertilization
Provide environment for a developing fetus
deliver, feed and nurture offspring
Produce female sex hormones
Hormones of the reproductive system
Female
Androgens; produce some changes at puberty
Estrogen; responsible for secondary sexual characteristics
GnRH; cause of secretion of FSH & L H from the anterior pituitary
Progesterone; completes the development of the uterus wall promotes gycogen storage
LH:Create a spike to Signal ovulation
FSH: stimulates 1 egg to develop
Male
FSH: Stimulates sertoil cells of seminferous tubulars
Androgens: create male sex hormones
LH:Promotes development of intertitial cells
Testosterone: is responsible for secondary male sexual characteristics
Events of the female hormonal cycles
Follicular phase
first day of the period and ovulation. Estrogen rises as an egg prepares to be released.
ovulation (14 days)
release of the egg from the ovary and when Estrogen peaks and then drops
menstration pahse
the shedding of the uterine lining. Levels of estrogen and progesterone are low.
luteal phase
between ovulation and before menstruation, when the body prepares for a possible pregnancy and Progesterone is produced, peaks, and then drops.
proliferative phase
the uterine lining builds back up again.
The secretory phase
The uterine lining produces chemicals that will either help support an early pregnancy or will prepare the lining to break down which becomes a period.
Anatomy of male reproductive structures
Seminal vesicles; Sakrete sand alkaline fluid containing nutrients that helps regulate PH of
semen.
Ejaculatory ducks; Located in prostate gland and delivers sperm to you the Urethra
Epididymis; It creates a tube from the testes to the dutus end the sperm becomes more bile and develop the ability to fertilized egg
Prostate gland; it is at the base of the uterine bladder and it secretes a thin milky fluid that contains nutrients for sperm
Scrotum; is the posterior to the penis protects and helps regulate temperature of the testes
Testes; are located in the scrotum
Penis ; it secretes urine and Seaman and it's located on the outside of the body
Urethra; it connects from the bladder to the penis and secretes urine and semen
Bulbourethral gland; lubercates the end of the penis.
Ductus deferens it conveys the sperm to the ejaculatory duct
Anatomy of female reproductive structures
Cervix; between the uterine and the Lumen of the vagina
Myometrium; is the middle layer of the uterus
Ovary; it produces the sex hormones for females and is located in the lateral wall of the pelvic cavity
Uterine tube; leads from the ovaries to the uterus and is the site for fertilization
Uterus; it maintains a development of the embryo
Vagina; located inside of the body and is also a birth canal
Infundbulum ; rleases the egg and is above the firmbrae
Perimetrium; Outermost layer of the uterus
Labrium minimus; It is between the labia major and provides an opening for the urethra and the vagina
Endometrium; the innermost layer of the uterus
Labia majus; it encloses and protects the external organs
Lumen of the vagina; is located below the cervix
Fimbrae; Is on the uterine tube
Disorders associated with the reproductive system
AIDS
Human
immunodeficiency virus
(HIV)
Symptoms: Fever, weakness, infections, cancer
Treatment: Drugs to treat or delay symptoms
Chlamydia infection
Symptoms: Painful urination and intercourse,
mucous discharge from penis or vagina
Treatment: Antibiotics
Chlamydia trachomatis
bacteria
Gonorrhea
Treatment: Antibiotics
Symptoms: In women, usually none; in men,
painful urination
Neisseria gonorrhoeae
bacteria
Genital herpes
Treatment: Antiviral drug
(acyclovir)
Symptoms: Genital sores, fever
Herpes simplex 2 virus
(HSV2)
Syphilis
Symptoms:
no symptoms a
damage to heart, liver, nerves, brain
Treatment:
Antibiotics
Treponema pallidum
bacteria
Genital warts
Symptoms:Warts on genitals
Treatment: Chemical or surgical
removal
Human papilloma virus
(HPV)
Methods and Classification of contraceptives
Mechanical Barriers
Diaphragm
Must be inserted into vagina every time for sexual intercourse it has no hormones
iternal Condom
Is a condom that is inserted into the vagina
External Comdom
is a condom that is put onto the penis before intercourse
Rhythm Method
abstinence from sexual intercourse around
time of ovulation, can not determine time of ovulation
Coitus Interruptus
withdrawal of penis from vagina before
ejaculation
Chemical Barriers
Spermicides
creams, foams, jellies that contain chemicals to kill the sperm and need to be ut in
pill
Injectable Contraception
injection of a progesterone derivative
prevents follicle maturation and ovulation
Intrauterine Devices (IUDs)
implanted in the uterus are either toxic to sperm and egg cells or prevent implantation of embryo
Contraceptive Implants:
implantation of a rod containing
progestin under the skin in the arm
Sterilization
vasectomy in male
tubal ligation in female
surgical methods of permanently preventing
pregnancy
