Reproductive organs
Male
Testis
Produces Sperms
Scrotum
Keep the testis and the penisout of the body
Epididymis
Where sperms produced bythe testis are stored
Urethra
Tube which carriers bothsperm and urine out of thebody
Sex Glands
Releases fluid that nourishes andprotects the sperms, and formssemen
Sperm Duct
Tube that carriers spermsfrom the epididymis to theurethra
Female
Fallopian tube
Carries ovum to uterus, and hascilia to sweep ovum to theurerus
Vagina
Site where sperms aredeposited during sexualintercourse
Ovary
Produces sex hormones and ova
Cervix
Neck of the uterus whichwidens during child birth
Uterus
Structure whereby the fertilised ovum isimplanted in, and also where ovum isdeveloped into zygote and foetus duringpregnancy
Birth control
Preventing fertilisation
Condom
Worn over the erected penis
Barriers the eggs and sperms
Diaphragm
Placed over the cervix
Barriers the spemrs and eggs
Spermicide
Kills sperms
Preventing ovulation
Contraceptive pills
Contains synthetic femalesex hormones
Suppresses the developmentand release of the eggs
Preventing the developmentof a fertilised egg
Intrauterine device
Inserted into the uterus, which preventsimplantation of the fertilised egg in theuterus
Sterilisation
Ligation (Females)
Tie and cut Fallopian tubes
Vasectomy (Males)
Tie and cut the sperm duct
Menstrual Cycle
Menstruation
Day 15 of the cycle
Contractions cause cramps
Thickening of uterine lining
To prepare for implantation, the liningthickens and becomes spongy, and full ofcapillaries
Ovulation
Day 1416 of the cycle
Considered the most fertile period
When it stops
Temporary
When a person is pregnant, menstruationstops but thick uterine wall is maintained tocushion the developing fertilised ovum
Permanent
Stops at menopause onwards,which happens after 50 yearsold+
Puberty
Male
Testis and penis increase in size
Height rapidly increases
Reproductive system becomesactive
Ejaculation starts
Hair grows on face, chest,pubic areas
Female
Ovaries and vagina increase in size
Menstruation occurs
Hair grows on face, pubic areas
Hips widen and become rounder
Height rapidly increases
Breast develop
Fertilisation
Sperm meets the ovum in theFallopian tube and fertilisationoccurs
One sperm penetrates
Fertilised egg is called the zygote
Sexually transmitted infections
Caused by viruses and microorganisms
Transmitted by:
Skin to skin contact
Contact with bodily fluids
From infected mother to foetus
From infected mother to babyduring childbirth
Different infections
Gonorhea
Caused by sperical bateria
Transmitted through
Sexual intercourse
Mother to baby through childbirth
Symptoms
Painful sensation during urination
Newborn may be blind
Can be treated with antibiotics
Syphilis
Caused by spiral bacteria
Transmitted through
Sexual intercourse
Mother to foetus during pregnancy
Symptoms
Nonitchy skin rash
Deformed joints
Paralysis
Acquired Immune DeficiencySyndrome
Caused by HumansImmunodeficiency Virus
Transmitted through
Sexual intercourse
Sharing of injectionneedles with infectedpeople
Blood transfusion
Infected mother to childduring pregnancy orchildbirth
Symptoms/effects
HIV attacks white blood cells, thereforethe immune system of the person isreduced
Currently no cure
Abortion
Use surgical procedure to remove thedeveloping embryo
Complications may rise
Infections of the uterus
Weakening of thecervix
Heredity
The transmission of geneticcharacteristics from parents tooffspring
Sperm which contains father's DNA
Ovum which contains mother's DNA
Zygote contains mixture offather and mother's DNA
