Why this matters

Diagrams label parts but skip what they do. This is the functional map — whether you're tracking fertility, managing periods, or filling gaps from school health class.

Ovaries — egg warehouse & hormone factory

  • Egg release

    One mature egg per cycle in most months — ovulation.

  • Estrogen & progesterone

    Shape lining, bone health, mood, and libido.

  • Track timing

    Use our ovulation calculator as an estimate — clinical tests are more precise.

Fallopian tubes — the meeting point

After ovulation, the egg travels through a fallopian tube. Fertilization usually happens here. Inflammation or scarring (sometimes after infection) can block passage and affect fertility.

Uterus — where implantation happens

Each cycle, estrogen builds a blood-rich lining; progesterone stabilizes it for possible pregnancy. No implantation → the lining sheds as your period.

Cycle red flags

  • Heavy bleeding or clots larger than a coin
  • Cycles shorter than 21 or longer than 35 days
  • Bleeding between periods or after sex

Cervix, vulva & vagina

  • Cervix

    Mucus changes around ovulation (clear, stretchy at peak fertility). Pap screens ≠ STI tests.

  • Vulva

    External: labia, clitoris, openings. Pain location helps diagnosis.

  • Vagina

    Internal canal — different from vulva; don't use terms interchangeably.

Three hormone phases (simplified)

1

Follicular

Estrogen rises; lining rebuilds; egg matures.

2

Ovulation

LH surge; egg released.

3

Luteal

Progesterone dominates; if no pregnancy, period starts.

When to see a gynecologist sooner

  • Period pain that limits daily life (endometriosis is underdiagnosed)
  • Trying to conceive 12+ months under 35 (6+ if 35+)
  • Missed periods with negative or positive pregnancy test
  • Pelvic pain, unusual discharge, or fever
