Egg Freezing Process: Step-by-Step Guide for Women

Fertility Treatment /

Your Future. Your Timeline. Your Choice Suppose you are 28, successful in your career, maybe still seeking the right person, or even just not ready to have a child yet, and that your biological clock doesn’t stop to wait for any of that. As women age, their egg count and quality naturally decrease — making it harder to conceive over time. For many women, this biological reality clashes with the demands of building a career, pursuing education, managing health challenges, or simply not being ready yet. The good news? Modern medicine has given women something that is unheard of; the power to stop time biologically.   Oocyte cryopreservation, also referred to as egg freezing, is among the most empowering fertility preservation techniques present-day. As you sail through a cancer diagnosis, as you plan your future, or as you just desire the freedom to form your own family at your own pace, the egg freezing procedure can offer you choices that were, literally, unavailable a generation ago. What Is Egg Freezing? Egg freezing is a fertility preservation technique where the eggs (oocytes) of a woman are taken out, frozen, and stored to be used later. She is ready to conceive, and the eggs are thawed, fertilised with sperm in the laboratory, and the resulting embryo is transferred into the uterus. This method of cryopreservation of eggs was once thought to be an experiment. It is now an established, medically accepted practice – and the rates of success have dramatically increased with the use of a process known as vitrification (freezing-flashing), which radically lowers the amount of ice crystals and the quality of the egg. Who Should Consider Egg Freezing? The preservation process of the eggs applies to a large group of women, such as:   Late 20s or early 30s women who are yet to conceive. Women with cancer who require fertility preservation before chemotherapy or radiation. Women who have diseases such as endometriosis or premature ovarian insufficiency. Women intending to have gender-affirming procedures. Women who merely desire reproductive insurance to rest easy Egg freezing is best done below 35 years due to the optimum egg quality and quantity at that age. Nevertheless, a consultation can still be beneficial to women even in their early 40s.  Step-by-Step the Egg Freezing Process Being aware of every step of the fertility preservation process will help you become less anxious and will enable you to make wise decisions. The following is what to expect: Step 1: Initial Consultation & Fertility Assessment Your experience starts with an extensive consultation. In this visit, I evaluate: Ovarian reserve – through blood tests of AMH (Anti-Mullerian Hormone) and FSH (Follicle-Stimulating Hormone) levels. Antral follicle count (AFC) – through transvaginal ultrasound to determine the number of eggs on board. General reproductive health – medical history and lifestyle. This assessment will provide us with a good understanding of the manner in which your ovaries will react to stimulation and the number of eggs that we can reasonably anticipate retrieving. Step 2: Ovarian Stimulation (Days 1-12) After being cleared to undergo the procedure, you will start controlled ovarian hyperstimulation (COH). This involves:   Hormone injections (gonadotropins) are self-administered daily (usually 10-12 days). These hormones make the ovaries produce more than one egg in a cycle, which is the usual one. Frequent blood monitoring and ultrasound (2-3 days) to monitor follicle development and levels of hormones. Dosage modifications according to the requirements to optimize the response and reduce the chances of ovarian hyperstimulation syndrome (OHSS). The majority of women are able to cope with this stage. Light bloating or mood swings are normal and short-term.  Step 3: Trigger Injection When follicles are of the ideal size (around 1820mm), a trigger shot (usually an hCG or a GnRH agonist) is applied. The injection completes egg maturation and is carefully timed – the egg harvest is 34-36 hours later. Step 4: Egg Retrieval The minimal-invasive procedure under mild sedation or anaesthesia will make you feel comfortable during it.   A fine needle is inserted, with the help of transvaginal ultrasound, into the ovarian follicles through the vaginal wall. The fluid, in which the eggs are held, is aspirated. The entire procedure takes about 20–30 minutes.   A temporary rest in the recovery area will follow, and you will be discharged on the same day. The majority of the women resume normal activity after 24-48 hours. Step 5: Egg Freezing (Vitrification) After retrieving, the eggs are directly evaluated by an embryologist. Freezing is done to mature eggs (MII stage).   The eggs are then quickly frozen to -196 °C using liquid nitrogen — a process that prevents ice crystal formation and preserves structural integrity. The ultra-fast freezing prevents the appearance of ice crystals. That may cause destruction of the fragile egg structure. This greatly improves the survival rates when the egg is thawed.   The duration of frozen egg storage is 10 years or longer, depending on local laws. Step 6: Storage Your frozen eggs are kept in a cryopreservation facility with strict conditions. They are tagged, indexed, and checked constantly to provide integrity. When You Are Ready: Embryo Transfer Process When you choose to use up your frozen eggs, then this is what will occur: Thawing – Eggs are slowly warmed; most eggs can withstand the thaw (8090%). Fertilisation – A single Sperm (that of a partner or donor) is inserted using ICSI (intracytoplasmic sperm injection) to fertilise the egg. Embryo growth- the fertilised egg grows in the lab over a period of 3-5 days. Embryo transfer — This is a painless, fast procedure, which does not need anaesthesia and is done with the help of a catheter, inserting the embryo into the uterus. Pregnancy test– It is a blood test about 10-14 days following the implantation. It determines whether the implantation was successful. How Many Eggs Do You Need? This is one of the most common questions patients ask. As a general guide:   Age at Freezing Recommended Eggs for ~70% Success Rate

Recurrent IVF Failure: Causes Explained & Advanced Treatment – Dr. Sharmistha Sarkar

Fertility Treatment /

IVF is a hope for many couples who find it hard to conceive naturally. Nonetheless, prolonged failure of the cycles may be emotionally and physically draining. In case you have already had several failures, it is possible to seek the advice of an IVF specialist who will be able to evaluate the initial cause of the problem and point you to the correct path. What is Recurrent IVF Failure? Recurrent IVF failure is said to be the inability to get pregnant when one or two IVF cycles fail with good-quality embryos. It is a complicated question. It is required to be evaluated by an experienced IVF doctor. Every case is individual, and the insight into the causative agent is the clue to the higher success rates. Most Frequent Causes of Recurrent IVF Failure Various reasons can cause recurrent IVF Failure. You need to know: 1. Poor Embryo Quality The quality of embryos is a significant aspect of IVF. Genetically abnormal embryos can fail to implant or develop even after fertilization takes place. A skilled doctor may suggest the use of more sophisticated methods to determine the well-being of embryos. 2. Implantation Failure Even healthy embryos, in some cases, are not bound to the uterus. It happens sometimes due to complications during the uterine lining or embryo transfer. To address this issue, you need to consult with an IVF physician. 3. Uterine Abnormalities The presence of fibroids, polyps, or scar tissue in the uterus can interfere with implantation. These complications may be commonly diagnosed and remedied before the second round of IVF. 4. Hormonal Imbalances Hormones are also the key to the body’s readiness to get pregnant. The imbalances of progesterone, estrogen or thyroid hormones can affect embryo growth and implantation. 5. Age Factor One of the most significant factors in IVF success is female age. The older a woman is, the worse her egg quality and quantity become, and this may result in recurrent IVF failures. You can increase your chances by consulting an IVF specialist in Siliguri early. 6. Genetic Issues The two partners might be carrying some genetic deformities that influence the development of embryos. Such issues can be diagnosed with the help of sophisticated tests and treated properly. 7. Male Factor Infertility IVF failure may also be caused by issues such as low-quality sperm or DNA fragmentation. Both partners are carefully evaluated by a qualified fertility specialist to ensure an accurate and comprehensive diagnosis. Advanced IVF Treatment Couples who experience recurrent IVF failure have several solutions available to them due to the medical advancements. The ability to get access to modern and effective treatments is guaranteed by choosing the appropriate IVF specialist. 1. Preimplantation Genetic Testing (PGT) PGT has been useful in the selection of genetically healthy embryos, which stands a higher chance of successful implantation. 2. Blastocyst Transfer The increased success rates of embryo transfer at a later stage (blastocyst stage) are better than those of low-stage embryo transfer. 3. Endometrial Receptivity Analysis (ERA) ERA tests aid in establishing the most appropriate time at which an embryo can be transferred, and this increases the chances of implantation. 4. ICSI (Intracytoplasmic Sperm Injection) This method is applicable in cases of male infertility, whereby a single sperm is injected into an egg. Advantages of Choosing the Right Specialist There are various advantages if you choose the right specialist. Some of the benefits are discussed below. Perform Detailed Investigations An experienced IVF professional starts by carrying out effective research to know your reproductive health. It can be blood tests, hormonal analysis, ultrasound, and semen analysis. Such tests are used to recognize the existing hidden problems and make sure that before treatment, nothing significant is omitted. Determine the Cause of a Failure Upon going through all test results, the doctor concentrates on determining the underlying cause of infertility or recurrent IVF failure. They are not made upon conjecture, but rather a proper diagnosis is arrived at through medical evidence. This is important as by curing the specific issue, a successful pregnancy is likely to be achieved. Customize Treatment Plans The fertility process of all couples is unique, and there is no single set of solutions. A qualified expert will create a unique treatment plan regarding your condition, age, and medical history. This might be medications, IUI, or techniques of advanced IVF that can be customized to provide you with a favorable result. Emotional Encouragement Fertility can be considered to be an emotionally exhausting and stressful process, particularly when it has taken numerous failures. A caring IVF professional will stay with you and hear you out, and will patiently understand your issues. This emotional support makes couples remain optimistic and assured during the process.

Induction of ovulation Fertility treatment usually begins with ovulation induction for women who do not ovulate regularly or at all. Drugs given in this process help the ovaries to release eggs regularly. Through ultrasound and hormone tests, doctors carefully monitor the cycle to ensure that the treatment is working. This approach is straightforward, relatively less invasive, and can actually improve the chances of natural conception when done at the right time. 2. Intrauterine Insemination (IUI) IUI is a widely used and simple fertility method. During this process, specially prepared sperm are deposited directly into the uterus at the time of ovulation. This enhances the odds of fertilization as it situates sperm closer to the egg. IUI is mainly recommended for couples with mild fertility problems, unexplained infertility, and certain male factor problems. It’s fast, typically painless, and doesn’t require surgery. 3. Ensuring Human Reproduction through Modern Measures IVF is among the most sophisticated and effective fertility therapies. As a renowned IVF specialist in Siliguri, Dr. Sharmistha Sarkar offers complete IVF management for couples with complicated issues. In this procedure, eggs are retrieved from the ovaries and fertilized with sperm in a laboratory. After development, the embryo is put back into the uterus. IVF is very effective and is recommended in case of blocked fallopian tubes, severe male infertility, or failed prior treatments. 4. Hormonal and Diagnostic Testing Before beginning any treatment, it is important to understand the cause of infertility. The diagnostic and hormonal tests are very useful in this. Blood tests, ultrasound scans, and other advanced tests may be recommended to look for problems with hormone levels, the ovaries, and other reproductive organs. A correct diagnosis assists in devising a focused and effective treatment plan, thereby enhancing the odds of success. When should you visit a fertility expert?

How the IVF Process Works in 5 Stages IVF offers a viable solution for the effective treatment of infertility problems. One of the most experienced IVF doctors in Siliguri, Dr. Sharmistha Sarkar ensures safe and advanced IVF care.   Ovarian Stimulation: The initial phase is referred to as ovarian stimulation that involves the administration of fertility drugs to encourage the ovaries to generate more than one egg. Doctors keep a close supervision of the progress during this period by conducting regular ultrasounds and blood tests that are taken to confirm the eggs are growing well. Collection of eggs: Collecting eggs is the second stage. When the eggs are ready, they are then taken out of the ovaries with a small surgery done under sedation. It is a fast process and takes approximately 20-30 minutes and patients can go home the same day. Laboratory fertilization process: Fertilization is carried out in a lab in the third stage. The retrieved eggs are mixed with sperm either through natural fertilization or using the assistance of ICSI (Intracytoplasmic Sperm Injection), a single sperm is injected into the egg. The eggs, which have been fertilized, then grow into embryos in the coming few days. Placing the embryo in the uterus: Embryo transfer is the fourth step. The healthy embryo is handpicked and inserted into the uterus with a thin catheter. It is an easy, painless process, which most times does not need anesthesia. Pregnancy Test: The last stage is the pregnancy test. Another blood test is done to ascertain the success of implantation about 10-14 days after embryo transfer. The doctor will provide the way ahead based on the results.  While IVF may seem complex, Expert guidance ensures a smooth and stress-free process.

Fertility Specialist in Siliguri: When Should You Seek Help?

Women’s Health /

Starting a family is one of the most meaningful journeys a couple can take — but for many, the path to parenthood is not straightforward. A mother plays a big role in determining the happiness of a family. Expanding a family is one of the most beautiful journeys of a mother. But it is not so smooth for everyone. They face various challenges in the journey of parenthood. Attempting to conceive a baby naturally is the first step for any couple. If natural conception has not been successful, it is time to consult a fertility specialist in Siliguri. Early treatment with Dr. Sharmistha Sarkar can pave the way for determining the problem. Understanding Fertility Challenges There is a prevalence of infertility that meets the eye. It is common in both men and women and may occur because of many reasons, including hormonal imbalance, lifestyle choices, or even underlying health conditions. A fertility specialist in Siliguri is prepared to examine these problems and offer a treatment that boosts your chances of conceiving. Fertility Specialist: When Do You Need to See One? It is important to know when to see a Fertility Specialist in Siliguri. The following are some of the typical cases in which you need professional assistance: 1. More Than a Year of Trying to Conceive When you are younger than 35, and your success has not been achieved after 12 months of continuous attempts, you have to see a doctor. 2. Trying for 6 Months (Age 35 or above) In women over 35, age decreases fertility. When you have been making 6 months of attempts and have not succeeded, do not postpone the consultation. 3. Irregular Periods or Amenorrhea Abnormal menstrual cycles can be a sign of hormonal issues or disorders such as PCOS, which can influence ovulation. 4. History of Miscarriages The frequent miscarriage of pregnancy could require a medical check-up and treatment by a well-trained IVF specialist in Siliguri. 5. Known Medical Conditions Such problems as endometriosis, thyroid diseases, or diabetes may affect fertility and need professional care. 6. Male Fertility Issues Poor sperm quality or low sperm count may also cause infertility. The fertility specialist examines the partners. Basic Problems of Infertility Knowledge of the cause assists in the selection of the appropriate treatment. A few of the usual causes are: Ovulation Disorders Ovulation disorders are caused by the failure of the ovaries to release eggs in a normal manner. It can be caused by such circumstances as PCOS or hormonal imbalance, and it becomes hard to conceive. Blocked Fallopian Tubes Fallopian tubes assist in the movement of the egg. The tubes move from the ovary to the uterus. Sometimes they become blocked or damaged by infection. Therefore, the egg and the sperm are unable to meet, resulting in no fertilization. Endometriosis This is a disorder in which the tissue resembling the uterine lining develops externally. It is painful, inflammatory, and can involve the ovaries, fallopian tubes, and general fertility. Hormonal Imbalances One should be very careful to check whether the menstrual cycle and ovulation are on time. These are two of the greatest factors in determining pregnancy. Any hormonal imbalance, such as estrogen, progesterone, or thyroid hormone, can lower the rate of pregnancy. Reduced Sperm Count or Motility Male fertility issues most commonly involve a low sperm count, poor sperm motility (movement), or abnormal sperm morphology (Size and shape of sperm) — any of which can make it difficult for sperm to reach and fertilise the egg. Lifestyle Changes, Such as Stress, Smoking, or Obesity One must be aware of a healthy lifestyle. Too much stress, excessive alcohol consumption and unhealthy diet, and obesity can hamper your fertility rate. It influences both the fertility among male and females. A qualified IVF specialist in Siliguri can help you with it. Patients are given tests and recommend the most appropriate treatment. Duties of a Fertility Specialist A Fertility Specialist in Siliguri is a specialist who provides you with personalized care depending on your condition. The process usually includes: Diagnosis Blood work, ultrasound, and semen analysis are some of the tests used to determine the problem. Treatment Options There are various treatments available nowadays for a successful pregnancy. Depending on the diagnosis, treatments may include: ● Ovulation Induction Ovulation induction is a therapy that assists in the stimulation of the ovaries to secrete eggs regularly. Special medicines are administered by doctors for the management and enhancement of ovulation, particularly when a woman has irregular periods or ovulation disorders. ● Medications The initial treatment is usually fertility drugs. They are used to control hormones, increase the number of eggs in females, and, in some cases, improve the quality of sperm in men. The prescription is normally given after a specialist has assessed them. ● Intrauterine Insemination (IUI) IUI is a less invasive and not very difficult procedure where healthy sperm are directly inserted into the uterus at ovulation. This augments the likelihood of fertilization because the sperm will be brought nearer to the egg. ● In Vitro Fertilization (IVF) IVF is a high-tech fertility therapy often suggested to patients. In this treatment, eggs are retrieved from the ovaries and fertilised in a laboratory setting. The resulting embryos are then transferred to the uterus. When some other treatment fails, then this treatment is suggested to the couples. Dr. Sharmistha Sarkar, a renowned fertility specialist in Siliguri offers comprehensive fertility care. She is understanding and compassionate. She offers quality care to couples who want to have a child and fulfil their dreams.
