Fertility Preservation Options for Young Women: Safeguarding Motherhood for the Future

Fertility preservation has become an essential option for young women who may face medical or surgical treatments that can affect reproductive health, as well as for women who wish to delay motherhood for personal, educational, or professional reasons. Advances in reproductive medicine now allow women to protect their fertility and maintain the possibility of having biological children in the future.

Medical treatments such as chemotherapy, radiotherapy, ovarian surgery, and autoimmune therapies can significantly reduce ovarian reserve or permanently damage reproductive function. Fertility preservation provides hope and control, allowing women to make informed decisions about their reproductive future before undergoing potentially sterilizing treatments.

Egg Freezing (Oocyte Cryopreservation)

 

Egg freezing, also known as oocyte cryopreservation, is one of the most widely used and successful fertility preservation techniques. In this process, a woman undergoes ovarian stimulation to produce multiple eggs, which are then retrieved and frozen using advanced vitrification technology.

Egg freezing is ideal for women who:

• Are about to undergo cancer treatment

• Have medical conditions affecting fertility

• Want to delay pregnancy for career or personal reasons

When the woman is ready to conceive, the frozen eggs can be thawed, fertilized with sperm through IVF, and transferred to the uterus. Egg freezing offers flexibility and preserves reproductive autonomy.

Embryo Cryopreservation

 

Embryo freezing involves fertilizing eggs with sperm before freezing. This option is suitable for women who have a male partner or choose to use donor sperm. Embryo cryopreservation has been used successfully for decades and offers high pregnancy rates when transferred later.

This method is often recommended when immediate fertility preservation is required and fertilization options are clear.

Ovarian Tissue Cryopreservation

 

Ovarian tissue freezing is an innovative option, especially beneficial for young girls or women who cannot delay cancer treatment. In this surgical procedure, a small portion of ovarian tissue containing immature eggs is removed and frozen.

Later, the tissue can be transplanted back into the body, allowing natural hormone production and the possibility of natural conception. This method is still evolving but has shown promising results.

GnRH Agonist Ovarian Suppression

 

GnRH agonist therapy involves temporarily suppressing ovarian function during chemotherapy. Although not a standalone fertility preservation method, it may help reduce ovarian damage when used alongside other preservation techniques.

---

In Vitro Maturation (IVM)

 

In Vitro Maturation (IVM) allows immature eggs to be retrieved without full ovarian stimulation and matured in the laboratory before freezing. This option is useful when hormonal stimulation is not advised.

Fertility Preservation Before Gender-Affirming Treatments

 

Fertility preservation is also important for individuals undergoing gender-affirming treatments. Transgender individuals may choose to preserve reproductive cells before starting hormone therapy or surgery.
