Dana De Guzman Period 3 Reproductive system
Major functions of the Reproductive system
to produce egg and sperm cells, transport and sustains the egg and sperm cells, nurture developing offspring, and produce hormones
Anatomy of male reproductive system
Scrotum protects the testis and keeps the temperature 5 degrees below the body temperature. Surrounds the testis
Testes responsible for making the sperm and involved producing hormone called testosterone
Epididymus stores the sperm for maturation smd transports it to the vas deferens
Vas deferens transport the mature sperm to the urethra in preparation for ejaculation
Seminal vesicle secretes alkaline pH to regulate the pH in the vagina and fructose to nourish the sperm. Combines with the sperm
Prostate gland secretes enzymes for the sperm to be able to move and liquifies the semen
Bulbourethral gland secretes lubricantion during sexual stimulation
corpus spongiosum and corpora cavernousom contain blood vessels that constrict and causes errection. Corpus spongiosum surrounds the urethra and corpora surrounds the spongiosum.

Anatomy of female reproductive structures
ovary produces oocytes and female sex hormones
uterine tube conveys secondary oocyte toward uterus; site of fertilization; conveys developing embryo to uterus
uterus protects and sustains embryo during pregnancy
vagina conveys uterine secretions to outside of body; receives erect penis during sexual intercourse; provides a passageway for offspring during birth process
labia majora enclose and protect other external reproductive organs
labia minora forms margins of vestbule; protects openings of vagina and urethra
produces feelings of pleasure during sexual stimulation due to abundant sensory nerve endings in glans
vestibule space between labia minora that contains vaginal and urethral openings

Hormones of the reproductive system (Male and female)
female hormones
male hormones
testosterone regulate sex drive, bone mass, fat distribution, muscle mass and strength, and the production of red blood cells and sperm
estrogen: responsible for development of female secondary characteristics.
progesterone prepares the endometrium for a feritilized egg to implants and grow
Events of the female hormonal cycles
The anterior pituitary gland secretes follicle-stimulating hormone (FSH) and
FSH stimulates maturation of a dominant follicle.
Follicular cells produce and secrete estrogens.
a. Estrogens maintain secondary sex characteristics.
b. Estrogens cause the endometrium to thicken.
The anterior pituitary releases a surge of LH, which leads to ovulation.
Follicular cells become corpus luteum cells, which secrete estrogens and
a. Estrogens continue to stimulate uterine wall development.
b. Progesterone stimulates the endometrium to become more glandular and
c. Estrogens and progesterone inhibit the secretion of FSH and LH from the
If the secondary oocyte is not fertilized, the corpus luteum
As the concentrations of estrogens and progesterone decline, blood
The uterine lining disintegrates and sloughs off, producing a
The anterior pituitary gland is no longer inhibited and again secretes
The menstrual cycle repeats.
Disorders associated with the reproductive system
Syphilis sexually transmitted disease that can have very serious complications when left untreated bu it is simple to cure with the right treatment
genital herpes STD caused by the herpes simplex virus type (HSV-1) or type 2 (HSV2)
Chlamydia common nsecually transmitted disease (STD) that can be easily cured. If left untreated, chlamydia can make it hard for a woman to get pregnant
Gonorrhea sexually transmitted disease that affects both genders causes infections la genitals, rectum, and throat
Hepatitis, inflammation of the liver
AIDS/HIV collection of symptoms and infections associated with acquired deficiency of the immune system
HPV/Genital warts usually appears as a small bump of group of bumps in genital area
PID inflammation of the upper genital tract due to an infection on women
Methods and classification of contraceptives
coitus interruptus is the withdrawal of the penis from vagina before ejaculation
Rhythm method is abstinence from sexual intercourse around time of ovulation
mechanical barriers prevents sperm from entering the vagina during sexual intercourse
chemical barriers contain spermicides
combined hormone contraceptives contain estrogen and progestins to prevent pregnancy
injectable contraception: a progesterone derivative prevents follicle maturation and ovulation but it only works for 3 months
contraceptive implants is implantation of a rod containing progestin under the skin in the arm; prevents follicle maturation and ovulation for 3 years
intrauterine devices implanted in the uterus are either toxic to sperm and egg cells. thickens endometrium to prevent implantation of embryo

Female sterilization fallopian tubes are cut and tied
male sterilization cuts and ties off the vas deferens
IUD injection of a progesterone prevents follicle maturation and ovulation (Injection in the uterus?)
Injectables progesterone derivative prevents follicle maturation and ovulation
pill voluntary regulation of the number of offspring produced
diaphragm a thin, flexible silicone that sits over the cervix
internal condom covers the inside of the vagina to create a barrier to stop the sperm from reaching the egg
external condom latex/silicone that goes over the penis
