As overseas fertility options continue to attract attention, many people only discover after they begin researching IVF that an entire cycle involves much more than simply “egg retrieval and embryo transfer.” From preliminary testing and ovarian stimulation to embryo culture and transfer, each stage involves different medical considerations.

 

What preparation is needed before starting IVF?

 

Before officially beginning a cycle, the fertility status of both partners needs to be evaluated.

 

For women, this usually includes age, AMH, baseline hormone levels, and antral follicle count, while men generally need to undergo semen analysis. Depending on their medical history, doctors may also recommend additional tests.

 

These results can affect the ovarian stimulation protocol and the overall cycle plan. If you are planning overseas IVF, it is also important to understand the validity period of test reports, prepare the necessary medical records, and arrange the timing of overseas treatment in advance. This can help avoid discovering after arrival that additional testing is required.

 

How does ovarian stimulation work?

 

During a natural menstrual cycle, usually only one dominant follicle ultimately matures. IVF ovarian stimulation uses medication to encourage multiple follicles to develop simultaneously, allowing more mature eggs to be retrieved.

 

During stimulation, doctors continuously monitor follicle development through ultrasound and hormone testing and adjust medication according to the actual response. The goal of stimulation is not simply to obtain as many eggs as possible. The proportion of mature eggs, as well as subsequent fertilization and embryo development, are equally important.

 

What happens after egg retrieval and fertilization?

 

Once the follicles have reached an appropriate stage of development, the doctor will schedule egg retrieval. At the same time, the male partner provides a sperm sample according to the medical team’s instructions.

 

After the eggs and sperm are obtained, the laboratory performs fertilization. Depending on the specific circumstances, conventional IVF or ICSI may be used. The resulting embryos are then cultured in the laboratory while their development is monitored.

 

Why do many families focus on IVF-PGT?

 

Once embryos develop to the blastocyst stage, IVF-PGT, also known as third-generation IVF or IVF-PGT embryo genetic testing, can be performed to analyze the chromosomal status of the embryos.

 

Compared with evaluating embryos based only on their appearance, PGT can provide additional genetic information at the embryo level, supporting subsequent embryo selection and transfer. For families seeking a more systematic approach to embryo planning, IVF-PGT has become an important part of the overseas assisted reproduction process to understand.
