It’s a deeply personal decision, and if you’re reading this, you are likely navigating the complex intersection of personal goals, career ambitions, and the relentless reality of the biological clock. You may be asking, "Why choose egg freezing for fertility preservation?" The answer is simple: autonomy. Egg freezing is not just a medical procedure; it is a powerful way to decouple your reproductive timeline from the rest of your life's schedule.

 

In the rapidly advancing world of Assisted Reproductive Technology (ART), the ability to freeze and successfully thaw a woman’s unfertilized egg is a true revolution. Let's delve into the science, the process, the advantages, and the practical considerations of Egg Freezing in Kenya, empowering you to make the choice that is best for your future.

 

The Core Science: How Egg Freezing Works

 

To appreciate why egg freezing for fertility preservation, you must understand the scientific breakthrough that made it reliable. The egg (oocyte) is the largest cell in the human body, containing a high water content. Traditional freezing methods (slow-freezing) often caused destructive ice crystals to form inside the cell, shattering the delicate cellular structure and rendering the egg unusable. This led to very poor success rates historically.

 

The Breakthrough: Vitrification

 

The game-changer in egg freezing technology is vitrification—often referred to as “flash-freezing.”

 

  1. Dehydration: Before freezing, the egg is carefully treated with high concentrations of cryoprotectants. These specialised chemicals act as an anti-freeze, rapidly drawing out the water from the egg’s interior.
     

  2. Ultra-Rapid Cooling: The dehydrated egg is then plunged almost instantaneously into liquid nitrogen at an ultra-low temperature.
     

  3. Glass-Like Solidification: This rapid cooling bypasses the formation of ice crystals. Instead, the cell solution instantly solidifies into a glassy, non-crystalline state.

 

The Result: Vitrification boasts a high survival rate, often exceeding 90% for high-quality, mature eggs upon thawing. This innovation is why Egg Freezing in Kenya is now offered as a standard, highly effective clinical procedure, no longer considered experimental.

 

The Egg Freezing Cycle: A Step-by-Step Guide

 

The process of egg freezing is essentially the first half of an In Vitro Fertilisation (IVF) cycle, minus the fertilisation and transfer steps.

 

Step 1: Initial Assessment and Planning

 

Your journey begins with a consultation at a specialised Fertility Clinic like Fertility Point. The doctor will perform two key tests to assess your ovarian reserve:

 

  1. Anti-Müllerian Hormone (AMH) Blood Test: A reliable indicator of the remaining quantity of eggs.
     

  2. Antral Follicle Count (AFC): An ultrasound scan performed early in your cycle to count the small, resting follicles in your ovaries, which correlates with how many eggs can be stimulated for retrieval.

 

Step 2: Ovarian Stimulation

 

To maximise the number of mature eggs retrieved in a single cycle, you will take injectable hormonal medications (Gonadotropins) for about 8 to 14 days. These hormones stimulate the ovaries to mature multiple follicles (each containing one egg), rather than the single egg matured in a natural cycle.

 

Step 3: Monitoring

 

Throughout the stimulation phase, you will have regular visits to the Fertility Clinic for transvaginal ultrasound scans and blood tests. This monitoring allows the doctor to track the growth of the follicles and adjust medication dosages precisely, ensuring optimal egg maturity while preventing the risk of Ovarian Hyperstimulation Syndrome (OHSS).

 

Step 4: The Trigger Shot

 

Once the follicles reach the optimal size (typically 17–20mm), a final hormone injection—the "trigger shot" (usually hCG)—is administered. This is timed precisely, typically 35 to 36 hours before the retrieval, to prompt the final maturation of the eggs.

 

Step 5: Egg Retrieval

 

This is a minor surgical procedure performed at the Fertility Clinic under light sedation. Guided by ultrasound, the specialist uses a fine needle attached to a suction device to gently aspirate the fluid from the mature follicles and collect the eggs. The procedure usually takes 20 to 30 minutes.

 

Step 6: Cryopreservation (Vitrification)

 

In the laboratory, mature, healthy eggs are immediately assessed and flash-frozen using the vitrification technique before being stored in liquid nitrogen tanks for future use.

 

Why Choose Egg Freezing for Fertility Preservation? The Advantages

 

The benefits of egg freezing extend far beyond just delaying motherhood; they offer control, peace of mind, and higher success rates in the future. This is the heart of why to choose egg freezing for fertility preservation.

 

1. Halting the Biological Clock


(i) Preserving Quality: Egg quality declines rapidly, particularly after age 35, mainly due to the rise in chromosomally abnormal eggs. Freezing eggs at a younger age (ideally before 35) means that when you use them later (even at age 40 or 45), they still carry the higher genetic potential of your younger self.
 

(ii) Higher Success Rates: The chance of a successful live birth is directly linked to the age of the egg. Using frozen eggs at 30 provides a significantly higher chance of success than using fresh eggs retrieved at 40.

 

2. Social and Personal Flexibility

 

(i) Career and Education: Egg freezing allows you to focus on career growth, education, and personal development without the looming anxiety of diminishing fertility.
 

(ii) Finding the Right Partner: It removes the intense pressure to find a life partner or start a family before you are ready, providing autonomy over your relationship choices.

 

3. Medical Necessity (Oncofertility)

 

For women facing necessary medical treatments that threaten their fertility, egg freezing is a lifeline:

 

(i) Cancer Treatment: Chemotherapy and pelvic radiation can severely damage or destroy ovarian reserve. Freezing eggs before starting treatment ensures the possibility of having biological children later.
 

(ii) Risk of Premature Ovarian Failure (POF): For women with a family history of early menopause or certain genetic conditions, freezing eggs is a preventative measure.

 

4. Backup for IVF Success

 

In an IVF cycle, if a man is unable to produce a sperm sample on the day of retrieval, frozen eggs can be a critical safeguard. They can also be a valuable reserve if a fresh IVF cycle fails, allowing the option of another attempt without undergoing another full retrieval.

 

Disadvantages and Risks of Egg Freezing

 

While the technology is advanced, egg freezing is not without its considerations and risks.

 

Category Disadvantage / Consideration
No Guarantee The most significant drawback is that a frozen egg does not guarantee the birth of a baby. The success depends on survival after thawing, successful fertilisation (usually via ICSI), embryo development, and successful implantation.
Cost The procedure is a significant financial investment, covering medication, monitoring, retrieval, and annual storage fees. This cost can be compounded if multiple cycles are needed to achieve the target number of eggs.
Physical Discomfort The hormonal stimulation phase involves daily injections and can cause temporary side effects such as bloating, mood swings, and breast tenderness.
Procedure Risks Though rare, there are minor risks associated with the egg retrieval, including infection, bleeding, and the serious but preventable risk of Ovarian Hyperstimulation Syndrome (OHSS).
Emotional Pressure While intended to reduce pressure, the cycle itself can be emotionally taxing, and the act of freezing can sometimes lead to a false sense of security, encouraging delay until an age where even frozen eggs may face implantation challenges.

 

Egg Freezing in Kenya: Success Rates and Target Numbers

 

The success of Egg Freezing in Kenya depends heavily on two key variables: the age at freezing and the number of mature eggs frozen.

 

The Age-Success Correlation

 

The younger you are at the time of freezing, the fewer eggs you need to achieve a reasonable chance of a live birth.

 

Age at Freezing Eggs Needed for? 60% Live Birth Chance
35 and Under 10 to 15 mature eggs
36-39 15 to 20 mature eggs
40-42 20 or more mature eggs (often requiring multiple cycles)

 

It's essential to understand that success is not measured by a single egg, but cumulatively across the entire cohort of eggs frozen. Your specialist at a leading centre like Fertility Point will work with you to determine a realistic target number based on your AMH and age.

 

The Thawing and Fertilisation Process

 

When you are ready to use your frozen eggs, they undergo the following steps:

 

  1. Thawing: The vitrified eggs are rapidly warmed. High-quality eggs have a survival rate of $90\%$ or more.
     

  2. ICSI: Due to the hardening of the egg's outer shell during freezing, Intracytoplasmic Sperm Injection (ICSI)—where a single sperm is injected into the egg—is almost always required for fertilisation.
     

  3. IVF/Embryo Transfer: The fertilised eggs (now embryos) are grown in the lab, and the highest-quality embryo is transferred to the woman's uterus.

FAQ's

What is egg freezing?

Egg freezing is a medical process where a woman’s unfertilized eggs are collected, matured, and preserved at very low temperatures using a technique called vitrification. These eggs can later be thawed, fertilized, and used for pregnancy.

Why do women choose egg freezing?

Women choose egg freezing to preserve their fertility for future family planning. It offers flexibility for career, education, finding the right partner, or protecting fertility before medical treatments like chemotherapy.

What is the best age to freeze eggs?

The ideal age is before 35, as egg quality and quantity are highest. However, women between 36–40 can still freeze their eggs with good success rates, though they may need more cycles.

Is the egg freezing procedure painful?

The process involves hormonal injections and a short retrieval procedure under sedation. Most women report mild discomfort, bloating, or cramping for 1–2 days.
