Study Notes
Sexual Reproduction in Animals
- Reproduction is the process by which living organisms produce offspring to ensure their species' survival.
- Sexual reproduction involves the fusion of haploid gametes: egg cells (female) and sperm cells (male), resulting in a diploid zygote.
- Offspring inherit genetic material from both parents, resulting in unique combinations.
Reproduction in Earthworms
- Earthworms are hermaphroditic, possessing both male and female reproductive organs.
- Mating involves two worms aligning their ventral surfaces, with their anterior ends facing opposite directions.
- Each worm transfers sperm to the other's sperm-receiving sacs.
- The clitellum secretes a mucous ring which collects the sperm, creating a cocoon containing fertilized eggs.
- Development of the embryo occurs externally within the cocoon.
Reproduction in Frogs
- Frogs are either male or female.
- The female's ovaries produce eggs, which are coated with a jelly-like material as they pass through the oviducts.
- During mating, the male clasps the female, stimulating egg release into the water.
- The male then releases sperm, fertilizing the eggs externally.
Reproduction in Chickens
- Roosters and hens lack external genitalia; fertilization occurs through a cloacal kiss.
- Sperm travels through the rooster's vas deferens to the sperm sacs, and is released into the hen's cloaca.
- Sperm travels through the hen's oviduct, awaiting the egg's release.
- Fertilization takes place in the infundibulum.
- The egg is further developed in the magnum, isthmus, and shell gland, resulting in a shelled egg.
- Development of the embryo takes place externally within the incubated egg.
Human Reproduction
- The female reproductive system includes the ovaries, fallopian tubes, uterus, cervix, and vagina.
- The ovaries produce eggs and release them into the fallopian tubes.
- The uterus is where a fertilized egg implants and develops.
- The cervix connects the uterus to the vagina.
- Menstruation occurs monthly, involving the shedding of the uterine lining if fertilization does not occur.
- The male reproductive system includes the testes, vas deferens, prostate gland, and penis.
- The testes produce sperm.
- The vas deferens transports sperm to the urethra.
- The prostate gland secretes fluid that mixes with sperm to form semen.
Birth Control Methods
- Condom - barrier preventing semen from entering the vagina.
- Pills - oral contraceptives containing estrogen and progestin to prevent ovulation.
- Hormonal Ring - releases estrogen and progestin to prevent ovulation, thicken cervical mucus, and thin the uterine lining.
- IUD - a T-shaped device inserted into the uterus to prevent pregnancy.
- Injectable contraceptives - medroxyprogesterone acetate injection suppressing ovulation.
- Surgical Sterilization - permanent methods including female sterilization (tubal ligation) and male sterilization (vasectomy).
- Implant - a rod inserted under the skin releasing progestin to prevent pregnancy.
- Coitus Interruptus - withdrawal of the penis before ejaculation to prevent sperm from entering the vagina.
- Calendar Rhythm Method - tracking menstrual cycles to predict ovulation and avoid intercourse during fertile periods.
- Patch - skin patch releasing estrogen and progestin to prevent pregnancy.
Sexually Transmitted Infections (STIs)
- Herpes Simplex Virus (HSV) - causes oral or genital herpes with symptoms ranging from mild to severe.
- Mycoplasma genitalium (MG) - a sexually transmitted infection similar to chlamydia, potentially asymptomatic or symptomatic.
- Human Papillomavirus (HPV) - causes warts and can lead to cancers of the cervix, anus, penis, vagina, vulva, and oropharyngeal areas.
- STIs can be prevented through abstinence, using condoms, getting tested regularly, and receiving vaccinations against preventable STIs.
