What should you know about transfer of embryo to uterus?

After eggs are collected and fertilised in the laboratory, the fertility team selects an embryo for transfer. A speculum opens the vagina, and a soft catheter passes through the cervix into the uterus. The embryo is released into the uterine cavity, then the catheter is removed. The transfer itself is usually brief, although preparation and positioning take longer.

A fresh transfer may happen in the same treatment cycle, while some embryos are frozen for a later cycle. Progesterone may be prescribed to support the uterine lining. Transfer does not confirm pregnancy; a pregnancy test is arranged after the interval advised by the fertility team.

Follow the clinic's instructions about medicines, timing and whether your bladder should be comfortably full. Take prescribed treatment exactly as directed, including [Micronised Progesterone](/materials/micronised-progesterone/). Wear comfortable clothing and tell the team about allergies, bleeding or new pain before the appointment.

Afterward, ordinary gentle activity is generally possible unless your clinician gives different advice. Avoid changing medicines or taking a pregnancy test earlier than advised. Contact the clinic if you are unsure about bleeding, cramps or a missed dose.

Contact your fertility clinic promptly for heavy bleeding, worsening pelvic pain, fever, faintness, breathing difficulty or marked abdominal swelling. These symptoms need assessment rather than waiting for the planned pregnancy test. Severe one-sided pain, collapse or heavy bleeding warrants urgent emergency care.

Ask which embryo is being transferred, whether the cycle is fresh or frozen, how to use progesterone, when to test for pregnancy, and which symptoms should trigger an urgent call.
