As assisted reproductive t

echnology continues to advance, more families are planning for parenthood earlier than ever before. When exploring Mexico surrogacy, many intended parents will come across the term "ovarian stimulation." In fact, ovarian stimulation is one of the most important stages of the entire treatment cycle. A well-managed stimulation protocol not only affects how many mature eggs can be retrieved but also influences embryo development and the overall treatment timeline.

Why Is Ovarian Stimulation an Essential Step in Mexico Surrogacy?

During the Mexico surrogacy process, if the intended mother uses her own eggs, ovarian stimulation and egg retrieval are typically completed before in vitro fertilization (IVF), embryo culture, and embryo transfer.

Under normal circumstances, only one dominant follicle matures during a natural menstrual cycle. The goal of ovarian stimulation is to encourage multiple follicles to develop simultaneously, increasing the number of mature eggs available and improving the chances of creating high-quality embryos.

It is important to understand that more eggs do not necessarily mean better outcomes. Physicians develop individualized stimulation protocols based on factors such as age, ovarian reserve, AMH (Anti-Müllerian Hormone), antral follicle count (AFC), hormone levels, and medical history to obtain an appropriate number of high-quality mature eggs while prioritizing patient safety.

What Are the Main Stages of an Ovarian Stimulation Cycle?

The first stage is fertility evaluation.

Before treatment officially begins, physicians perform a series of baseline examinations, including AMH testing, reproductive hormone assessment, ultrasound evaluation, and antral follicle count. These results provide a comprehensive picture of ovarian function and help guide the treatment plan based on the patient's reproductive goals.

The second stage is ovarian stimulation.

Once the menstrual cycle begins, fertility medications are administered according to the individualized treatment plan. Ovarian stimulation typically lasts about 8 to 12 days. During this period, regular ultrasound examinations and hormone monitoring are performed to track follicle development, allowing physicians to adjust medication dosages when necessary.

The third stage is the trigger shot.

Once most follicles have reached the appropriate level of maturity, the physician schedules the trigger injection. This medication promotes the final maturation of the oocytes and allows egg retrieval to be precisely timed.

The fourth stage is egg retrieval.

Egg retrieval is generally performed approximately 34 to 36 hours after the trigger shot. The procedure is usually carried out under intravenous sedation, and most patients experience little to no pain during the procedure. After a short recovery period, most individuals are able to gradually return to their normal daily activities.

Every healthy embryo begins with well-managed ovarian stimulation. From fertility evaluation and individualized treatment planning to follicle monitoring and egg retrieval, each step is built upon scientific assessment and precision medicine.
