Ovulation
Ovulation is the release of an egg from the ovaries. During a woman's follicular phase several follicles
start to mature and nourish the eggs. Typically one dominant follicle will continue to maturity and the
others will degenerate. When ovulation occurs the egg will break out of the follicle and start to travel
along the fallopian tube where conception may take place. The left over follicle becomes the corpus
luteum and either degenerates (if conception hasn't occured) and menstruation will start, or if conception
has occurred it continues to produce progesterone through the early weaks of pregnancy.
