Fertility preservation
Fertility preservation encompasses a range of medical techniques designed to protect a person’s reproductive potential against the effects of time, medical treatments, or life circumstances that may compromise fertility.

What is fertility preservation?
Fertility preservation involves storing reproductive cells or tissue for future use. The goal is to maintain current reproductive quality, even if biological conditions change over time or due to medical reasons. Depending on each case, fertility preservation may include:
- Egg freezing (oocyte cryopreservation).
- Sperm freezing (semen cryopreservation).
- Embryo preservation.
- Ovarian or testicular tissue preservation (in specific cases).
Each option has specific indications and should always be assessed on an individual basis.
What do egg and sperm freezing involve?
Vitrification is an ultra-rapid cryopreservation technique that allows reproductive cells to be stored at extremely low temperatures without the formation of ice crystals, preserving their structure and functionality.
Who is fertility preservation recommended for?
Fertility preservation is not limited to a single profile. It may be recommended in a variety of personal and medical situations, including:
Individuals who wish to postpone motherhood or fatherhood for personal, professional, or lifestyle reasons, without compromising their current reproductive potential.
Patients undergoing cancer treatment or other medical therapies that may affect fertility, such as chemotherapy, radiotherapy, or certain surgical procedures.
Individuals with signs of low ovarian reserve, hormonal imbalances, or a family history of early menopause, who wish to take proactive steps.
People without a stable partner, couples wishing to delay parenthood, or anyone wanting to preserve future reproductive options before making definitive decisions.
Fertility preservation techniques
Egg freezing (Oocyte cryopreservation)
Egg freezing is a procedure that allows eggs to be preserved through vitrification, enabling their future use in fertility treatments.
Sperm freezing (Semen cryopreservation)
Sperm freezing is a technique that allows sperm cells to be stored at very low temperatures for later use in assisted reproduction treatments.

Frequently asked questions about fertility preservation
The answers to these frequently asked questions have been prepared by the editorial team at GAIA Fertility Clinic and medically reviewed by Dr. Grether Pérez to ensure the information is accurate, up to date, and based on scientific evidence.
Up to what age can I preserve my fertility?
From a biological perspective, the earlier fertility is preserved, the better the reproductive quality tends to be. However, there is no single age that is right for everyone.
The most important thing is to seek information early, understand your personal reproductive situation, and explore options before fertility becomes compromised.
What is the fertility preservation process like?
The process begins with a personalised medical assessment, including a review of medical history and any necessary fertility tests.
Based on factors such as age, medical circumstances, and life plans, the most appropriate fertility preservation technique is recommended.
The corresponding medical procedure is then carried out, and reproductive material is stored through cryopreservation at extremely low temperatures.
When the time comes to use the preserved reproductive material, the most appropriate fertility treatment is carefully planned according to the patient’s circumstances.
Can I preserve my fertility before cancer treatment?
Yes, fertility preservation can be considered before certain cancer treatments, as some treatments may affect ovarian function.
When medically indicated, it is important to assess fertility preservation options before starting treatment.
