Infertility is becoming increasingly common among women in Hong Kong. Studies suggest that one in six couples experience difficulty conceiving. In recent years, egg freezing has emerged as a viable option for women who wish to preserve their fertility. However, the success of this method is closely linked to the age at which the eggs are frozen. The earlier the procedure is performed, the higher the quality of the eggs and the better the chance of pregnancy later. This is where AMH testing plays a critical role.
What Is AMH and What Does It Tell Us?
AMH, or Anti-Müllerian Hormone, is secreted by the small follicles in a woman’s ovaries. The level of AMH in the blood reflects the ovarian reserve, meaning the remaining quantity of eggs in the ovaries. Generally, a higher AMH level indicates a greater number of remaining eggs. As women age, ovarian reserve gradually declines, and AMH levels decrease accordingly.
Interestingly, a woman’s ovarian function does not always match her chronological age. Some women experience earlier decline in ovarian reserve, which can affect egg quality and the ability to conceive. AMH testing allows women to gain a clearer understanding of their reproductive health and helps inform decisions about family planning or fertility preservation.
Early Testing Enables Better Planning
If a young woman discovers that her AMH level is lower than average for her age group, this may suggest an earlier decline in ovarian function. In such cases, she may choose to conceive earlier or consider freezing her eggs while they are still of good quality. For those who are not ready to have children but want to keep the option open, egg freezing offers a proactive solution.
How Does Egg Freezing Work?
Egg freezing involves a process of hormonal stimulation to encourage multiple eggs to mature in a single cycle. Once matured, the eggs are retrieved through a minor surgical procedure and frozen at a temperature of minus 196 degrees Celsius. Under such conditions, the eggs can be preserved without any deterioration in quality over time.
For example, if a woman freezes her eggs at age 32, those eggs will retain the same quality even if used at 39. This provides an opportunity to delay childbearing without compromising the potential for pregnancy.
Freezing Eggs Increases Chances, Not Guarantees
While egg freezing can increase the likelihood of a future pregnancy, it does not guarantee success. Other factors, such as the male partner’s sperm quality and the condition of the uterus, will still play a role. Egg freezing should be viewed as an option to extend fertility potential, not as a certainty.
Conclusion
AMH testing is a straightforward but powerful tool that helps women understand their ovarian reserve and plan accordingly. With greater awareness and earlier action, women can take control of their reproductive choices without compromising other life goals. For those considering egg freezing or concerned about fertility, it is advisable to consult a reproductive specialist for personalized guidance.
