Ovary is a special reproductive organ in women. In ovaries follicles develop into oocytes; eggs are released from ovaries; remaining part of the follicles forms corpus luteum. This generates women’s menstrual cycles. There are three phases of menstrual cycles: follicular phase, ovulation and luteal phase. Each phase has distinct with featured hormone levels. The hormones are produced in three areas: hypothalamus, anterior pituitary gland and ovaries. The hypothalamus produces gonadotropin releasing hormone (GnR) which stimulates the pituitary gland. The pituitary gland produces both follicle stimulating hormone (FSH) and luteinizing hormone (LH) which stimulate the ovary. The ovary secrets estrogen and progesterone. FSH and LH inhibits production of GnRH. Low concentration of estrogen increases release of FSH from the pituitary gland. High level of estrogen decreases FSH and increases LH secretion causing LH surge. This is called hypothalamus-pituitary-ovarian axis. This axis is in control ovulation. Any dysfunction of this axis may result in anovulation and irregular period. It also can lead to infertility caused by no ovulation. The leading cause of infertility is ovulation dysfunction, either no ovulation or irregular ovulation.
Anovulatory cycle is a menstrual cycle which ovulation does not occur and there is no egg released from the ovaries. Women would think if they have periods, they must be ovulating. This is not necessarily the case. You don’t have to ovulate to have periods. This is called anovulatory cycle. The cycles could be regular with variations of period intervals. These cycles are without ovulation and a luteal phase. Anovulation is a common cause of infertility which occurs in up to 40% of infertile women. Women without ovulating may have irregular periods, or no periods. It is possible that women with regular periods have no ovulation. Once they try to conceive and they start to detect the problem. Because no egg is released and fertilization becomes impossible, the women cannot conceive. Basal body temperature charting is a valuable tool to identify anovulation.
Normal menstrual cycles are 28 days (21-35 days) with follicular phase, ovulation and luteal phase. Ovulation occurs in the middle of the cycle and corpus luteum which produces progesterone forms after ovulation. After 14 days, corpus luteum decayed and stopped producing progesterone. Uterine inner lining shed off without the support of progesterone in the case without pregnancy. This is called progesterone withdrawal bleeding. In the case of anovulation, there is no progesterone produced. Bleeding is caused by inability of oestrogen to support uterine inner lining growth. It is called oestrogen breakthrough bleeding.
If you want to get pregnant, it is important to make sure you ovulate.
