Ultrasound examination (US) is one of the key diagnostic methods in obstetric practice, allowing timely monitoring of the condition of both the fetus and the surrogate mother. In surrogate pregnancy programs, the importance of ultrasound increases significantly as it ensures safety and control at every stage.

Medical Ultrasound: A Modern Diagnostic Methoedical ultrasound is a cutting-edge diagnostic method based on the use of high-frequency sound waves to study the internal structures of the body. It is used both for visualizing anatomical structures.

Principles of Ultrasound Operation

Diagnostic ultrasound relies on transducers—special ultrasound probes that generate sound waves with frequencies above 20 kHz, which are beyond the range of human hearing. In medical practice, frequencies in the megahertz (MHz) range are most commonly used, enabling high-quality imaging of internal organs.

Types of Diagnostic Ultrasound

• Anatomical Ultrasound. This type of ultrasound produces detailed images of internal organs and tissues, used to study organ structures, detect abnormalities, and assess size and shape.

• Functional Ultrasound. Combines anatomical imaging with data on tissue movement, blood flow velocity, tissue elasticity, and other physical characteristics. It creates "informational maps" that help doctors visualize functional changes in organs.

The Role of Ultrasound in Pregnancy Diagnosis

Early Pregnancy (5–7 Weeks):
The first ultrasound is performed to confirm pregnancy, evaluate the condition of the gestational sac, and rule out abnormalities.

Key Goals of Early Ultrasound:

• Verifying the embryo's viability and heartbeat.

• Determining the number of embryos.

• Ruling out ectopic pregnancy.

• Assessing the condition of the endometrium and other reproductive organs.

This stage is crucial for both doctors and genetic parents as it ensures the pregnancy is progressing as expected.

Ultrasound in the First Trimester

At 11–14 weeks, a second ultrasound is performed, including comprehensive screening to assess the fetus's condition and detect potential abnormalities.

Key Goals of First Trimester Ultrasound:

• Measuring the nuchal translucency to evaluate the risk of chromosomal abnormalities.

• Assessing the development of major organs and systems.

• Confirming gestational age.

• Examining the placenta and amniotic fluid.

At this stage, the reproductive organs of the surrogate mother are also assessed to minimize risks.

Ultrasound in the Second Trimester

A critical diagnostic stage occurs between 18–22 weeks of pregnancy, focusing on a detailed analysis of fetal anatomy.

Parameters Evaluated During This Period:

• Development of internal organs such as the brain, heart, kidneys, stomach, and others.

• Condition of the spine and limbs.

• Volume of amniotic fluid.

• Placental location.

At this point, the baby’s gender can also be determined if it is important to the genetic parent(s).

Ultrasound in the Third Trimester

At 30–34 weeks, a control ultrasound is performed to assess fetal development and the surrogate mother's readiness for delivery.

This Ultrasound Evaluates:

• Fetal weight and growth.

• Placental condition, including its maturity.

• Amniotic fluid levels and quality.

• Fetal position (head or breech presentation).

Additional ultrasounds may be performed if needed to refine data or address complications.

Ultrasound in Surrogacy Programs

In surrogacy programs, the genetic parent(s) are informed of the ultrasound results, which allows them to remain involved and maintain an emotional bond with the child.

Depending on medical conditions, more frequent and more extensive ultrasound scans may be required, minimizing risks and allowing timely response to changes.

Technological Advancements in Ultrasound

Modern ultrasound devices provide not only two-dimensional imaging but also 3D and 4D scanning. These technologies offer detailed insights into the fetus's condition and allow observation of fetal movements in real-time. This is particularly valuable for genetic parent(s) as it enhances their understanding of the baby’s development.

Medical Recommendations for the Surrogate Mother

To successfully complete a surrogacy program, it is essential to strictly follow medical advice:

• Attend all scheduled ultrasounds and other examinations.

• Promptly report any changes in health status.

• Maintain a healthy lifestyle and adhere to nutritional recommendations.

Ultrasound remains an indispensable tool for monitoring pregnancy, ensuring the safety and health of the future child.
