Pressing Pause On Your Fertility With Cryopreservation
The reproductive needs of American adults have evolved, and fertility clinics aim to keep up with the times. Now, there are strategies like in vitro fertilization (IVF) that help infertile couples, same-sex couples, or single women achieve pregnancy. Perhaps the most practical strategy in fertility treatment is the cryopreservation of reproductive material. Cryopreservation uses sub-zero temperatures to preserve egg and sperm for use later. Egg and sperm cryopreservation is particularly useful for individuals who need to preserve fertility. This is a similar process used in storing donor eggs and donor sperm, which is used in cases of severe infertility. Some people may be on the fence, but there are some fantastic benefits to freezing eggs or sperm, especially if starting a family is on the horizon.
The big chill for men and women
Egg and sperm cryopreservation is a multi-step process that allows for storing without needing a partner or immediate use. Men will provide the appropriate sperm sample. Women will be required to take a hormone medication to help produce multiple follicles. This process is monitored over a 10-14 day period. For sperm cryopreservation, the sample is washed and concentrated to ensure maximum quality. For egg cryopreservation, multiple eggs are extracted via a minimally invasive procedure. By using ultrasound, a catheter, and a small suction device, multiple follicles are extracted. Once the eggs or sperm are ready, the fertility clinic uses liquid nitrogen and a process called vitrification to freeze the eggs. Here are 3 compelling benefits of using cryopreservation.
1. Work while preserving your future family
While young women are still starting families, some are opting for fulfilling careers, business, sports, or other endeavors. Some men and women would prefer to delay pregnancy for the ideal partner, which can take time. Women experience a diminished ovarian reserve, especially from age 35. Getting pregnant naturally becomes more difficult. Cryopreservation allows individuals to save eggs or sperm at a younger, healthier stage to be used later. With IVF, younger, more viable eggs, sperm, and embryos are available for each cycle.
2. Improved success rates with younger eggs or sperm
Delaying pregnancy to pursue work activities or find a suitable partner does not mean fertility waits, too. There is a higher risk of developing subfertility or infertility with age. Poor lifestyle habits can affect the hormones responsible for fertility, or a preexisting condition can impact reproductive health. This should not prevent couples from trying naturally first. However, cryopreservation serves as an excellent backup plan. Using these frozen eggs or sperm can produce higher success rates than fresh samples harvested at an older age.
3. Safeguard against medical curveballs
Some men and women can encounter medical emergencies or health scares that can impact fertility. For instance, certain cancers can require radiotherapy or chemotherapy. Studies show that these treatments can severely damage reproductive organs, leading to infertility. Some surgeries to remove tumors or address underlying health problems can also damage reproductive organs. For individuals hoping to start a future family with genetic ties, there is now a way to reserve sperm and eggs before treatment.
Take note of these considerations
Cryopreservation is an effective form of fertility preservation but does have risks and considerations. The viability of frozen eggs and sperm is directly linked to age. Women over 35 are more likely to produce less viable eggs. Men can still produce samples of high sperm quantity at older ages but can experience quality issues. The hormone therapy and egg retrieval process can be physically and emotionally demanding. Take enough time to prepare for cryopreservation. Egg and sperm cryopreservation and storage can be costly and are not covered by insurance. Despite the challenges, technological advancements have improved egg and sperm survival rates after thawing. Cryopreservation provides the best opportunity for preserving fertility for future use.
So, should you freeze?
Cryopreservation is a great tool for safely storing eggs and sperm samples for years. The process was primarily for donors but also helps individuals or couples preserve fertility. Whether for personal reasons, health reasons, or to increase the success rate of future IVF cycles, the benefits are undeniable. The decision to freeze is ultimately up to individuals based on lifestyle, personal goals, and health. Having access to healthier eggs and sperm can improve the chances of creating a thriving family.
