### process:

Ovulation
* Most ovulation occurs after development
  - during menstruation
* can be rare without the help of medications
  - cause a slight increase in body temperature
  - even occur twice in the same cycle
  - increase discharge
* can occur at any time after the abortion so birth control is needed to prevent pregnancy
  - during estrus, but normally occurs at the end of the estrus period
  - before that first menstrual period
  - potentially occur twice in a womans cycle
* completes the first phase of the cycle.
* contributes to the decrease, but the majority of eggs are ultimately absorbed by the body.
* expels an egg cell from the follicle.
* happens when the egg leaves the ovary.
* initiates a complex chain reaction.
* involves a gentle extrusion of the granulosa and ovum into the periovarian space
  - the release of an egg from one or the other ovary
* is about to occur in a human female
  - believed to be induced by copulation
  - controlled by light
  - followed by the formation of a corpus luteum or corpora lutea
  - identified by serial sonography
  - impeded, and infertility is common
* is induced by copulation , as in most leporids
  - males while mounting the female from the back
  - induced, requiring copulation or suitable stimulation
  - inhibited and cervical mucous is thickened, preventing sperm from reaching the egg
  - reestablished quickly after discontinuation
  - regulated by hormone activity
  - related to standing heat
  - spontaneous and takes place during early to mid-estrus
  - stimulated by mating
* is suppressed because of the inadequate appropriate hormones
  - by lactation and births occur at two to four year intervals
* is the actual process of one ovary releasing an egg from the most dominant follicle
  - event that defines the phases of the menstrual cycle
  - name of the game
  - only time that the heightness is felt
* is the process of shedding of ovum from the Graffian follicle
  - where the mature egg is released from the ovary
* is the release of a fertile ocum or egg from the ovary into the fallopian tube
  - eggs from the ovaries
* is the release of the egg during the female estrous cycle
  - eggs from the ovaries and it travels down the fallopian tube
  - time of egg release
  - triggered by the release of a hormone in the brain via two regulating peptides
  - unlikely if only a few pills have been missed during a cycle
  - when the egg is released
* marks the beginning of the luteal phase
  - end of the follicular stage and the beginning of the second stage
* normally occurs twelve to sixteen days before the onset of menstruation.
* occurs about half way through the cycle.
* occurs after coitus
  - and the secondary oocyte only becomes a true ovum after syngamy
* occurs around day of the monthly menstrual cycle
  - the middle of a monthly cycle
  - at midcycle
* occurs at the end of metestrus
  - same time as gestation , allowing females to bear young every year
* occurs in response to changes in the hormonal balance regulating the menstrual cycle
  - the following spring and young are born in late summer
  - late in the period
  - mid-cycle
  - only after mating
  - spontaneously
  - when an ovum, or mature egg, is released from an ovary into the fallopian tube
* occurs when the egg is released from the follicle, or site of growth
  - follicle ruptures and releases the ovum into the body cavity
* occurs when the mature egg eaves the follicle and begins it' s trip through the oviduct
  - the follicle and begins it's trip through the oviduct
  - oocyte has reached the ootid stage of development
  - primary oocyte is released from the ovary and enters the uterine tube
* only occurs once in each cycle.
* physiological process resulting in the release of an egg from the ovary.
* pre-requisite for getting pregnant.
* requires a delicate balance of hormones
  - positive feedback by estrogen acting at the anterior pituitary
* sometimes can be harder to predict if a woman's cycles are irregular.
* stimulates the growth of the endometrium.
* strong stimulant of sex drive, and many birth control pills stop ovulation.
* takes place only in alternate years.
