Cryptomenorrhea, also known as “hidden menstruation,” occurs when menstruation happens but the blood is not visible due to an obstruction in the outflow tract. Common causes include:
1. Imperforate Hymen: A condition where the hymen completely covers the vaginal opening, preventing menstrual blood from exiting.
2. Vaginal Septum: A congenital condition where a wall of tissue divides the vagina, blocking the flow of menstrual blood.
3. Mayer-Rokitansky-Küster-Hauser (MRKH) Syndrome: A genetic disorder that can cause abnormalities in the reproductive tract, leading to cryptomenorrhea.
4. Uterine Didelphys: A rare congenital condition where a woman has two uteri, leading to potential blockage of menstrual flow.
These conditions can lead to symptoms like cyclical abdominal pain and primary amenorrhea (absence of menstruation by age 15). Diagnosis often involves imaging tests like ultrasound or MRI, and treatment typically includes surgical intervention to remove the obstruction.

Ovulation is a finely-tuned process involving hormonal interplay: 1.

Ovulation is a finely-tuned process involving hormonal interplay:
1. Follicle Development: In the first half of the menstrual cycle, follicle-stimulating hormone (FSH) from the pituitary gland stimulates the growth of ovarian follicles.
2. Mature Follicle Selection: Around mid-cycle, usually one follicle becomes dominant, maturing and producing estrogen.
3. LH Surge: The rise in estrogen triggers a surge in luteinizing hormone (LH) from the pituitary gland.
4. Egg Release: The LH surge causes the mature follicle to release its egg from the ovary into the fallopian tube, typically around day 14 in a 28-day cycle.
5. Luteal Phase: After the egg is released, the follicle transforms into the corpus luteum, secreting progesterone to prepare the uterine lining for a potential pregnancy.
This sequence ensures that an egg is available for fertilization during the most fertile part of the menstrual cycle.
