What should you know about luteal phase ovarian stimulation?

Ovarian stimulation uses gonadotrophins to encourage several follicles to grow. In a luteal phase protocol, the starting point is after ovulation rather than the beginning of a period. A GnRH antagonist or GnRH agonist may be used to control the hormonal signals that could trigger ovulation, depending on the clinic's plan. Ultrasound scans and hormone checks guide dose changes and timing. The aim may be egg freezing or another assisted reproduction pathway; it is not a promise of a particular number or outcome.

Ask for a written injection timetable, storage instructions, and a contact number for missed or late doses. Keep scan appointments because follicle growth can vary and the trigger timing matters. An AMH test may form part of ovarian reserve assessment, but it cannot predict the outcome of one cycle by itself. Tell the team about medicines, allergies, previous stimulation responses, and symptoms such as increasing abdominal swelling or pain.

Contact the fertility clinic promptly for severe or worsening abdominal pain, rapid swelling, repeated vomiting, difficulty breathing, faintness, or much less urine than usual. These symptoms can signal a significant treatment reaction and should not wait for the next scheduled scan. Follow the clinic's emergency instructions if symptoms become intense or sudden.

Ask why luteal phase stimulation is suitable for you, which medicines will be used, how follicles will be monitored, and when the trigger injection is planned. Ask whether eggs will be frozen, how many visits are expected, what side effects need a same-day call, and what happens if the response is lower or higher than expected.
