Dydrogesterone primed luteal phase stimulation may be better than follicular phase stimulation in patients with diminished ovarian reserve.

LPS may be beneficial especially in the patients with diminished ovarian reserve with follicular asynchronization in the menstrual onset. In addition, it should be kept in mind that dydrogesterone only may be used instead of gonadotropin-releasing hormone antagonist to prevent possible luteinizing hormone rise in LPS.
