REPRODUCTIVE SYSTEM

Functions of reproductive system

To produce hormones, offspring, gametes, to store/transport these gametes and nurture offspring

Use of these Hormones

Growth, development, sexual behaviors and drives

Primary reproductive organ

Produces gametes and hormones

Accessory organs

Transports and sustains the gametes, nurtures the offspring (female). Includes the duct system and external genitalia

Primary reproductive system for male and female

Testes and ovaries

Duct system for male

Male: epididymis, vas deferens, and urethra

Duct system for female

Female: fallopian tubes, uterus and vagina

Parts of male reproductive system

Testes, scrotum, epididymis, vas deferens, urethra, penis

Testes

Produce sperm and hormones

Scrotum

Provide testes with right temperature (3 degrees lower), protect testes

Epididymis

Temporary storage for sperm

Vas deferens

Propels sperm from their storage

Urethra

Carries both urine and sperm

Penis

delivers sperm into the female reproductive tract

Male reproductive functions and processes

Spermatogenesis, ejaculation, and testosterone production

Spermatogenesis

production of sperm, begins in puberty and continues throughout life

Ejaculation

Sudden ejection of semen

Testosterone production

Development of secondary sex characteristics in men

Parts of female reproductive system

ovary, fallopian tube, uterus, cervix, vagina, vulva

Ovary

Produces ova (exocrine), produces estrogen and progesterone (endocrine)

Fallopian tube

Fertilization site

Uterus

Receives and nourishes fertilized egg

Cervix

Pathway of fluids out of the uterus

Vagina

Birth canal

Vulva

Protects internal organs (external genitalia)

Female reproductive functions and processes

Oogenesis, menstrual cycle, hormone production

Oogenesis

Production of female gametes (ova)

Menstrual cycle

Monthly cyclic changes in the endometrium, responds to changes in hormones

Hormone production

Estrogen: appearance of secondary sex hormones, Progesterone: prepares endometrium for pregnancy

Mammary glands

modified sweat glands that produce milk, present in both sexes but not functional in males

Safe practices in reproductive and sexual health for males

Male: vasectomy, condom Female: tubal ligation, birth control

Safe practices in reproductive and sexual health for females

Female: birth control pills, and tubal ligation

Vasectomy

Minor operation into scrotum and vas deferens

Condom

Prevents transport of semen

Birth control pills

Medicine with hormones to prevent pregnancy

Tubal ligation

Permanent birth control, fallopian tubes tied

STIs

Chlamydia, genital herpes, and HIV

Chlamydia

Chlamydia trachomatis (usually no symptoms)

Genital herpes

Herpes simplex virus (blisters)

HIV

human immunodeficiency virus (attacks immune system, contact with infected body parts)

Protection against STIs

Condoms and vaccines
