This video clearly describes a normal ovulation process, with animation.
Details of ovulation can be confusing; it is a very well orchestrated, complex process full of ‘jargon’. See how an egg (oocyte) begins inside a follicle within the ovary. An ovary contains many follicles and more than one will begin to mature early in the menstrual cycle. Only one follicle however will continue to grow and support the developing egg within it. This dominant follicle releases a high level of estrogen, causing a surge of Luteinising Hormone (LH) resulting in the release of the egg from the follicle and ovary (ovulation). The fallopian tube ‘sweeps’ up the released egg and physical contractions force the egg down the fallopian tube into the uterus. The lifespan of the egg after it is released from the follicle and ovary is 12-24hrs, highlighting the importance of timed intercourse for fertilisation.
