Ovulation is an important part of the menstrual cycle in female vertebrates where the egg cells are released from the ovaries as part of the ovarian cycle. In female humans ovulation typically occurs near the midpoint in the menstrual cycle and after the follicular phase. Ovulation is stimulated by an increase in luteinizing hormone (LH).
The mature egg has a diameter of about 0.1 mm (0.0039 in), [29] and is the largest human cell. [30] Which of the two ovaries – left or right – ovulates appears random; [31] no left and right coordinating process is known. [32] Occasionally both ovaries release an egg; if both eggs are fertilized, the result is fraternal twins. [33]
The ovary (from Latin ōvārium 'egg') is a gonad in the female reproductive system that produces ova; [1] when released, an ovum travels through the fallopian tube/oviduct into the uterus. There is an ovary on the left and the right side of the body.
An ovarian follicle is a roughly spheroid cellular aggregation set found in the ovaries.It secretes hormones that influence stages of the menstrual cycle.In humans, women have approximately 200,000 to 300,000 follicles at the time of puberty, [1] [2] each with the potential to release an egg cell (ovum) at ovulation for fertilization.

The ovaries are small, paired gonads located near the lateral walls of the pelvic cavity. These organs are responsible for the production of the egg cells (ova) and the secretion of hormones. The process by which the egg cell (ovum) is released is called ovulation. The speed of ovulation is periodic and impacts the length of a menstrual cycle.
A female fetus (your mom, in this scenario) develops ovaries, with all the immature eggs she will ever have, by 20 weeks gestation. So, your X chromosome has likely existed for decades before you ...
Human egg cell. The egg cell or ovum (pl.: ova) is the female reproductive cell, or gamete, [1] in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one). The term is used when the female gamete is not capable of movement (non-motile).
The ovary itself is hollow, with eggs being shed into the central cavity, and thence passing directly into the oviduct. The enclosed nature of the female reproductive system in these fishes makes it impossible for eggs to escape into the general body cavity; a necessary development, given that thousands or even millions of eggs may be released ...
