Improving Fertility in Older Couples: Options for Assisted Reproductive Technology

Advanced maternal age pregnancy

I have been married to my wife for a year and a half (I am 48 years old, and my wife is 40).
We have been pregnant three times, but each time resulted in embryonic resorption (the doctor performed a transvaginal ultrasound and indicated that the embryo was underdeveloped and had no heartbeat), leading us to undergo a medical abortion after more than two months of pregnancy to remove the non-viable embryos.
In this situation, how can we improve our chances, or is it possible to pursue assisted reproductive technologies (such as screening sperm and eggs to select healthier ones)?

Dear Mr.
Wang,
You and your spouse are considered to be in a high-risk category for advanced maternal age.
Within a year and a half of your marriage, you have experienced three pregnancies, all of which unfortunately ended in miscarriage due to placental insufficiency.
This aligns with the diagnosis of recurrent pregnancy loss, which may have two primary causes: one being congenital chromosomal abnormalities, and the other being a chronic infection in the female body (such as Toxoplasma, Listeria, or cytomegalovirus).
I recommend that both of you visit an obstetrics and gynecology clinic for necessary examinations and genetic counseling.
As for the possibility of assisted reproductive technology, we can discuss that further once the underlying cause is determined.
If all tests return normal, it may simply be a matter of bad luck, as the general miscarriage rate for women is about 15-20% with each pregnancy.
Please keep trying, and I wish you both success in your future endeavors.
Best wishes,
Liang Yin Pan

More Info

Improving fertility in older couples, especially those who have experienced recurrent pregnancy loss due to embryo abnormalities, is a complex issue that requires a multifaceted approach. Given your situation, where you and your wife have faced three miscarriages attributed to embryonic development issues, it is crucial to explore both diagnostic and therapeutic options available through assisted reproductive technology (ART).

Understanding the Challenges
As couples age, particularly when the male partner is 48 and the female partner is 40, the likelihood of chromosomal abnormalities in embryos increases significantly. This is primarily due to the decline in egg quality and quantity in women as they approach their 40s. Men also experience a decline in sperm quality, which can contribute to issues with fertilization and embryo development. The combination of these factors can lead to higher rates of miscarriage, as seen in your case.

Diagnostic Steps
Before proceeding with ART, it is essential to undergo a thorough evaluation to identify any underlying issues that may be contributing to the recurrent pregnancy losses. This evaluation typically includes:
1. Genetic Testing: Both partners should consider genetic testing to identify any chromosomal abnormalities that could affect embryo viability. This can include karyotyping to check for structural abnormalities in chromosomes.

2. Hormonal Assessments: Hormonal levels, including FSH, LH, estradiol, and progesterone, should be evaluated to assess ovarian reserve and function.

3. Semen Analysis: A comprehensive semen analysis should be performed to evaluate sperm count, motility, morphology, and DNA fragmentation. High levels of DNA fragmentation can negatively impact embryo quality.

4. Uterine Evaluation: A hysterosalpingogram (HSG) or saline infusion sonogram (SIS) can help assess the uterine cavity for abnormalities such as polyps, fibroids, or scarring that could affect implantation.

Options for Assisted Reproductive Technology
Once the diagnostic workup is complete, you can discuss the following ART options with your fertility specialist:
1. In Vitro Fertilization (IVF): IVF allows for the direct fertilization of eggs with sperm in a laboratory setting. This method can be beneficial as it enables the selection of the best quality embryos for transfer.

2. Preimplantation Genetic Testing (PGT): PGT can be performed on embryos created through IVF to screen for chromosomal abnormalities before implantation. This can significantly increase the chances of a successful pregnancy by ensuring that only genetically normal embryos are transferred.

3. Egg and Sperm Donation: If the quality of your wife's eggs or your sperm is found to be significantly compromised, using donor eggs or sperm may be an option. This can enhance the chances of achieving a healthy pregnancy.

4. Lifestyle Modifications: Both partners should focus on optimizing their health through lifestyle changes. This includes maintaining a healthy weight, eating a balanced diet rich in antioxidants, reducing alcohol and caffeine intake, and quitting smoking. These changes can improve overall fertility and the chances of a successful pregnancy.

5. Counseling and Support: Given the emotional toll of recurrent pregnancy loss, consider seeking counseling or support groups. This can help both partners cope with the stress and emotional challenges associated with fertility treatments.

Conclusion
In conclusion, while the journey to parenthood can be fraught with challenges, particularly for older couples, advancements in reproductive technology offer hope. A comprehensive evaluation followed by targeted ART strategies, including IVF and PGT, can significantly enhance your chances of achieving a successful pregnancy. It is essential to work closely with a fertility specialist who can guide you through the process and tailor a treatment plan that addresses your specific needs and circumstances. Remember, persistence and support are key components of this journey, and many couples have successfully navigated similar paths to achieve their dreams of parenthood.
