In vitro fertilization is a series of medical procedures designed to treat infertility by combining collected eggs with the partner’s sperm in a laboratory.

Embryo Transfer

There are two types of embryo transfer:

1. Day 3 Embryo Transfer – performed approximately 72 hours after fertilization.
2. Day 5–6 Blastocyst Transfer – performed once embryos reach the blastocyst stage, considered more advanced.

Before the transfer, the fertility specialist discusses with the couple the number of embryos to transfer. Additional viable embryos may be frozen for later use. The procedure is painless, requires no anesthesia, and is performed using a thin catheter. Transferring more embryos may increase the chances of pregnancy but also increases the risk of multiples.

“You deserve to be heard, seen, treated with respect, and supported throughout your life.”

What Happens After the Transfer?

Following embryo transfer, rest is recommended. Mild cramping may occur. Physical exertion should be avoided for 3–4 days. Most patients can resume daily activities after 48 hours.

Afterward begins the 12–15 day waiting period before the blood test that confirms the outcome.

What Is the hCG Test?

hCG (“the pregnancy hormone”) is produced by the embryo’s trophoblastic tissue. Rising levels in blood or urine are the earliest indicator of pregnancy.

Two types of hCG tests exist:

• Qualitative – detects the presence of the hormone.
• Quantitative (beta hCG) – measures the hormone’s exact level.

Increasing hCG values confirm a progressing pregnancy. Early symptoms such as nausea, fatigue, and breast tenderness may appear. The first ultrasound confirms pregnancy location, viability, and rules out ectopic pregnancy, molar pregnancy, or anembryonic pregnancy.

How Does an IVF Pregnancy Evolve?

IVF pregnancies generally develop just like naturally conceived pregnancies. Risks may appear, especially in women over 35 or in multiple pregnancies. Nevertheless, IVF success rates continue to improve.
