As follicular phase proceeds, FSH secretion is inhibited due to rise in estrogen. During the follicular phase, LH rises until it peaks which in turns triggers ovulation. This is called the LH surge. Hormonal Control : Hormonal Control Clinical Importance : Clinical Importance Ovulatory disorders are one of the leading causes of female infertility. Ovulation Disorders: Inadequate Follicle Growth Patterns – Disorders of follicular development can cause an inadequate follicular size or inadequate estrogen production which can interfere with implantation. Premature Luteinization – In patients with higher than normal serum LH levels, premature production of progesterone by the follicle may result in improper changes in the cervical mucus, tubal mobility, or endometrium (uterine lining). The elevated LH levels may also adversely affect egg quality. Clinical Importance : Clinical Importance Luteinized Unruptured Follicle Syndrome (LUF syndrome) –Abnormal follicular development as well as pelvic adhesions can result in failure of the ovary to actually release the egg into the peritoneal (abdominal) cavity at the time of ovulation. Inadequate Luteal Phase – Hormonal imbalances can result in the development of a uterine lining that is out of phase with the fertilized egg. Thus, implantation or attachment of the egg to the uterine wall does not occur appropriately. This problem can cause infertility as well as recurrent miscarriages. Mnemonic : Mnemonic "FOL(d) M(a)PS" Ovarian cycle: Follicular phase, Ovulatory phase, Luteal phaseMenstrual cycle: Menstrual flow, Proliferative phase, Secretory phase The ovarian cycle controls the menstrual cycle. The cycles begin (day 0) when menstrual flow starts. At day 14, the luteal and secretory phases begin and last until day 28, after which the cycles begin again.
