Preparing the surrogate's uterus involves a carefully timed sequence to ensure the environment is receptive for the embryo. The cycle typically begins on the second or third day of the menstrual period with baseline ultrasound monitoring. We then introduce estrogen medication to steadily thicken the uterine lining and develop a healthy trilaminar pattern.
Once regular ultrasounds confirm the lining is ready, progesterone support is added to transition the lining into its receptive phase. On the designated day, the selected embryo is gently placed into the uterine cavity under ultrasound guidance via a fine catheter. A follow-up blood test confirms implantation a couple of weeks later. We encourage discussing individual protocol specifics with your fertility team.

Preparing a surrogate's endometrium requires precise hormonal coordination. Following a baseline pelvic scan at the cycle's start, oral or transdermal estrogen therapy is prescribed to encourage endometrial growth. We closely monitor lining thickness and blood flow through serial transvaginal ultrasounds.
When optimal endometrial characteristics are achieved, progesterone administration begins to initiate the receptive window. The embryo transfer is scheduled after an exact duration of progesterone exposure to match the embryo's developmental stage. Under ultrasound guidance, the embryo is gently transferred into the uterus using a soft catheter. Post-procedure care includes continuing hormonal support. Because individual responses vary, a customized plan supervised by a fertility specialist is always essential.

The journey toward embryo transfer in a surrogate involves synchronized clinical milestones. We begin with a baseline scan to ensure the pelvic organs are quiet before starting estrogen support. Estrogen helps develop a nourished, well-structured uterine lining over approximately two weeks.
Once serial monitoring confirms the lining is mature, progesterone is introduced. This vital hormone transforms the endometrium so it can accept and nurture an embryo. The actual embryo transfer is a quick, gentle procedure performed under abdominal ultrasound guidance, placing the embryo precisely within the uterine cavity. Supportive medications continue post-transfer until a pregnancy test is done. Please consult an IVF specialist for individualized protocol guidance.

During surrogate lining preparation, our primary objective is synchronizing endometrial receptivity with embryo development. We start by confirming a thin baseline lining during early menses, followed by progressive estrogen therapy. Regular ultrasound scans track endometrial thickness, pattern, and vascularity.
When the lining is adequately prepared, progesterone is initiated to open the 'window of implantation.' The embryo transfer itself is timed precisely based on the embryo's age (usually a Day 5 blastocyst). Using a soft catheter under ultrasound visualization, the embryo is smoothly delivered into the uterine cavity without anesthesia. Hormonal support continues through the luteal phase. I always recommend consulting your reproductive endocrinologist for a personalized evaluation.

Preparing a surrogate mother's uterus is a step-by-step clinical process designed to create optimal conditions for implantation. Following a preliminary ultrasound early in her cycle, she receives estrogen to stimulate healthy endometrial growth. We perform regular transvaginal scans to evaluate the lining's texture and thickness.
Once ready, progesterone is added to mature the endometrium, establishing the ideal timing for transfer. On the scheduled day, the embryo is carefully placed into the uterus using a delicate catheter under ultrasound monitoring. This is a painless, non-surgical step. Luteal phase support is maintained until the pregnancy test. Every surrogacy cycle is unique, so personalized medical supervision is crucial for safety and care.
