What are the common types of ovulation disorders? How can we tell if ovulation is occurring?
Types of ovulation disorders
1. Hypogonadotropic: such as pituitary failure
Clinical diagnosis: Absence of menstruation or scanty menstruation, abnormal BBT, and low LH and FSH (<5mIU/ml).
Treatment: HMG ovulation promotion
2. Hypergonadotropic: such as premature ovarian failure
Clinical diagnosis: age <40 years, amenorrhea, serum FSH and or LH >40 IU/L, reduced E2. Ovarian atrophy and lack of follicles.

Treatment: Mafron, Daine-35;
cc/HMG/letrozole-HCG.
4, hyperprolactinemia (hyperprolactinemia)

Treatment: Bromocriptine

3.Luteal phase progesterone measurement
4.Urine LH monitoring
