Reproductive Health Education Flashcards
Grade 9 · Health · Flashcards
Essential vocabulary covering reproductive anatomy, puberty, STIs, contraception, and reproductive hormones.
Flashcards
- GnRH (Gonadotropin-Releasing Hormone)
- Hormone secreted by the hypothalamus that signals the pituitary gland to release FSH and LH, initiating puberty and regulating the reproductive cycle.
- FSH (Follicle-Stimulating Hormone)
- Pituitary hormone that stimulates the development of ovarian follicles in females and sperm production in males.
- LH (Luteinizing Hormone)
- Pituitary hormone that triggers ovulation in females and testosterone production in males.
- Ovary
- Female reproductive glands that produce eggs (ova) and secrete estrogen and progesterone.
- Testes
- Male reproductive glands located in the scrotum that produce sperm and testosterone.
- Uterus
- The muscular, pear-shaped organ where a fertilized egg implants and develops during pregnancy; sheds its lining during menstruation.
- Chlamydia
- The most common bacterial STI; often asymptomatic; curable with antibiotics but can cause infertility if untreated.
- Herpes simplex virus (HSV)
- A viral STI that causes recurring sores or blisters; HSV-2 is typically genital; not curable but manageable with antiviral medications.
- Progesterone
- A female sex hormone that prepares the uterine lining for implantation and is essential for maintaining early pregnancy.
- Barrier method
- A contraceptive method that physically prevents sperm from reaching the egg; the male condom also reduces STI transmission.
- IUD (Intrauterine Device)
- A small T-shaped device inserted into the uterus by a healthcare provider; available in hormonal and copper (non-hormonal) forms; highly effective long-term contraception.
- Secondary sex characteristics
- Physical changes that occur during puberty driven by sex hormones; include breast development, pubic hair growth, voice changes, and hip/shoulder widening.
- Abstinence
- Refraining from sexual activity; the only 100% effective method of preventing both pregnancy and STI transmission.
- Zygote
- The single cell formed when a sperm fertilizes an egg; it contains the complete genetic information (46 chromosomes) of the future individual.
