Females {female reproductive organs} have ovaries, Graafian follicles, oogonia, Fallopian tubes, uterus, cervix, vagina, vulva, mons veneris, labia majora, labia minora, clitoris, and hymen.
Before birth, woman can lie in bed {lying-in}|.
Absorbent pads {sanitary napkin} can retain menstrual blood.
lesbianism {sapphism}.
female gonad {ovary, gonad}|.
Ovaries have follicles {Graafian follicle}|, which store oogonia. Ovaries produce eggs, one at a time in humans, and release mature ova into abdomen.
Ovum passes into tubes {oviduct} {Fallopian tube}|, for fertilization.
Oviducts lead to womb {uterus}|, where fertilized ovum attaches to wall and starts to develop.
uterus {womb}|.
Uteri have muscle rings {cervix}| at bottom openings.
From cervix, a tube {vagina}| leads to outside.
Thin membrane {hymen}| can cover vagina opening. Only three species have hymen.
hymen {maidenhead}.
At vagina opening are female sex organs {vulva}|.
Large flaps {labia}| {labia majora} with hair are around opening. Small flaps {labia minora} with no hair are over vagina.
A small penis-like organ {clitoris}| is in front of urethra.
Vulva top front {mons veneris} {mount of Venus} has fatty tissue covered by hair.
Ovaries have Graafian follicles, which store immature eggs {oogonium}.
Oogonia develop {oogenesis} to make oocytes.
Oogonia develop to make immature eggs {oocyte} {primary oocyte}.
If follicle matures, egg divides into main cell {secondary oocyte} and cell {polar body} with little cytoplasm.
One secondary oocyte divides into one large cell {ootid} and one polar body.
Polar bodies disintegrate, and ootid matures into egg cell {ovum} {ova}, with much yolk. Follicle cells kill bad eggs.
Cells {corona radiata} cover eggs. Hyaluronic acid carbohydrate holds cells together.
After sperm enters egg, membrane {fertilization membrane} forms, to block other sperm.
If egg has no fertilization, no egg implants, and uterus internal lining sloughs off {menstruation}| {menses}. Menstrual bleeding is greater in women than in other primates.
In most sexual animals, females have periods {estrus}| {heat, sex} {sexual readiness} {estrous cycle} when they are receptive to males, during which uterine glands secrete.
First-menstruation age {menarche}| is from 14 to 19 years old and decreases with city life, high-protein diet, and more exposure to males.
Menstruation typically ceases {menopause}| at 40 to 45 years old.
Females can have regular sex-receptive periods {rut, sex}|.
