Human Reproductive System
Sexual reproduction
Fusion of the nuclei of sex cells
Sperm cell
Zygote (fertilised egg)
Egg cell
Heredity
Inherit a mix of traits from both parents
Fertilisation and implantation
Fertilisation
Implantation
Zygote divides repeatedly to form embryo
Embryo moves to the uterus and implants in the uterine lining
Menstruation Cycle
Ovulation
Ovary releases an egg cell
Occurs every 28-30 days
Uterine lining thickens to receive zygote
Menstruation
Occurs when fertilisation does not happen
Uterine lining and blood vessels breakdown
Discharged through the vagina with the unfertilised egg
Cycle
Days 1-5
Menstruation
Days 6-9
Thickening of uterine lining
Preparation for implantation of embryo
Days 10-15
Egg is released into oviduct (14 days before cycle ends)
Cause fertilisation if sex occurs during this time
Days 16-28
Further thickening of uterine lining
Other conditions
Egg can survive 1 day after ovulation
Sperm can survive 3-5 days in the female reproductive system
Disruption of reproductive system
Substance abuse
Premature birth
Low birth weight
Smoking
Developmental issues with organs
Respiratory problems
Obesity
Diabetes
Birth control
temporary birth control
Both
Rhythm method
Avoid sexual intercourse during fertile period
Female
Contraceptive pills
Contains hormones that prevent ovulation
Intra-uterine device
Prevents implantation of zygote
Inserted into the uterus
Diaphragm
Covers the cervix, blocking sperm
Spermicide
Chemical that kills or blocks sperm
Male
Condoms
Impermeable to sperm and virus/bacteria
permanent birth control
Tubal ligation
Cuts the oviducts, prevents sperm from meeting egg
Vasectomy
Cuts the sperm ducts, preventing sperm from being ejaculated
Abortion (gay boo)
permanent termination of pregnancy
Sexually Transmitted Infections
Diseases (untreatable)
HIV
Turns into AIDS
Weak immune system, infections and death.
Diseases (treatable)
Syphilis
Symptoms
Sores, rashes, patchy hair loss
Long-term effects
blindness, paralysis, brain damage, insanity
Gonorrhoea
Symptoms
burning and discharge of pus during urination from the genitalia
Long-term effects
infertility, pelvic pain, abdominal pain
