Navigating IVF With Fewer Eggs
Diminished ovarian reserve (DOR) refers to a lower number or quality of eggs in the ovaries, often due to age, genetics, medical conditions, or prior treatments. While this diagnosis may feel discouraging, in vitro fertilization (IVF) can significantly improve the chances of pregnancy. Understanding the different IVF options available can help women with DOR feel confident.
Understanding DOR
A reduced ovarian reserve impacts both the quantity and potential quality of eggs available for fertilization. This condition may not cause obvious symptoms but is often identified through initial fertility testing, including antral follicle count (AFC), follicle-stimulating hormone (FSH), and anti-Müllerian hormone (AMH) levels. Lower AMH and higher FSH often suggest that fewer eggs remain in the ovaries, but each case is unique. Having a diminished ovarian reserve can make natural conception more difficult, but does not mean pregnancy is impossible.
The traditional IVF approach
In many cases, traditional IVF using a patient’s own eggs is often the first path explored when DOR is at play. With a diminished reserve, multiple IVF cycles may be needed to collect a suitable number of mature eggs. Clinics may use high-dose stimulation protocols or a modified approach, depending on how the ovaries respond. Frequent monitoring and customized adjustments during stimulation cycles allow the care team to optimize results. Embryo banking, which involves freezing embryos from multiple retrievals before transfer, can help improve outcomes. While success rates may be lower, many individuals with DOR can still conceive using personal eggs. No single protocol fits all, making personalization essential.
Boost potential with add-on procedures
When egg quantity is limited, maximizing the potential of each embryo becomes critical. Intracytoplasmic sperm injection (ICSI) can improve fertilization rates by injecting a single healthy sperm directly into each mature egg. Preimplantation genetic testing (PGT) may also be recommended to identify embryos with the correct number of chromosomes, increasing the chances of implantation and lowering miscarriage risk. Assisted hatching, which helps the embryo break through the outer shell, may further support success in certain cases. These add-on techniques, while optional, can enhance IVF outcomes when few embryos are available.
Supplements offer some support
Certain supplements and hormone strategies may improve egg response or quality. Coenzyme Q10 (CoQ10), Dehydroepiandrosterone (DHEA), and antioxidants are sometimes recommended during the weeks leading up to IVF. In omen with polycystic ovary syndrome (PCOS) and DOR, inositol may be added to the list. If a patient is deficient in vitamins, such as vitamin D or folate, supplementation prior to egg retrieval may be advised. Although no supplement can completely solve DOR challenges, consistent use can improve outcomes.
Considering donor eggs
For some individuals with very low egg counts or poor-quality eggs, donor egg IVF can provide another route to parenthood. Donor eggs come from healthy, pre-screened individuals and typically lead to higher pregnancy and live birth rates. This option allows for genetic contribution from a male partner and selection of donor traits. Many choose this path after 1 or more unsuccessful cycles using personal eggs with a DOR diagnosis.
Your path forward
Women diagnosed with diminished ovarian reserve benefit from early consultation with a fertility specialist to discuss time-sensitive options. Factors like age, hormone levels, and overall health will guide next steps. Whether pursuing traditional IVF, opting for add-on procedures such as ICSI, or using a donor, tailored planning increases the chance of success. With expert support and proactive choices, DOR does not have to limit future family-building goals.
