Coculture for Embryo Cumulus Cells
Steps Involved in IVF:
Procedure Description
Coculture for embryo cumulus cells is an advanced technique used in assisted reproductive technology (ART) to enhance the development and quality of embryos. This method involves the cultivation of embryos alongside cumulus cells, which are cells that surround the oocyte (egg) and play a crucial role in supporting its development. By mimicking the natural environment within the human reproductive system, coculture has shown potential in improving fertilization rates and overall embryo health.
The process begins with the extraction of cumulus cells during oocyte retrieval. These cells are carefully isolated and used to create a supportive culture medium in which embryos can grow. The cumulus cells secrete essential growth factors, cytokines, and other supportive substances that foster optimal conditions for embryo development. This environment closely resembles the natural in vivo conditions, making it more conducive to higher-quality blastocyst formation.
Research suggests that coculture may be particularly beneficial for patients who have experienced repeated implantation failures or poor embryo quality in previous in vitro fertilization (IVF) cycles. By nurturing the embryos in a more physiologically relevant environment, this technique can potentially improve the chances of successful pregnancy outcomes.
Procedure Duration
The duration of the coculture process for embryo cumulus cells typically aligns with the phases of a standard IVF cycle, but with the additional step of preparing the coculture medium. The entire procedure can be broken down into key stages:
- Preparation of Cumulus Cells: This stage occurs during oocyte retrieval, where cumulus cells are collected and isolated. The preparation process can take a few hours as the cells need to be handled with precision to maintain their viability.
- Coculture Phase: Embryos are placed in the coculture medium, where they remain for a few days. The exact length depends on the stage at which the embryos are transferred—typically between day 2 to day 5. During this period, embryos are monitored for growth, quality, and development into blastocysts.
- Embryo Transfer: After the embryos reach the desired development stage, they are transferred into the uterus. This phase takes place around day 3 or 5 post-fertilization, depending on individual treatment protocols.
Recovery time after embryo transfer is minimal, with patients often advised to rest for a day or two before resuming normal activities. Full implantation and confirmation of pregnancy generally occur within two weeks post-transfer.
Benefits
- Enhanced Embryo Development: Provides an environment that closely mimics natural conditions, promoting better embryo growth.
- Improved Implantation Rates: Higher potential for successful implantation and pregnancy, especially for patients with prior unsuccessful IVF attempts.
- Customizable Environment: The culture can be adjusted to match specific patient needs.
- Reduced Embryo Stress: Cumulus cells create a nurturing setting that reduces stress on the embryo, improving overall quality.
- Potential for Higher Live Birth Rates: Some studies indicate a correlation between coculture use and higher rates of successful live births.

- Specialized Expertise Required: The procedure demands a high level of technical skill, which may not be available at all fertility centers.
How to Choose the Right Doctor and Hospital
Selecting a qualified doctor and clinic for coculture and other IVF-related procedures is essential for success. Patients should research clinics with a proven track record in advanced reproductive techniques. Look for specialists who have significant experience in coculture, as well as positive patient outcomes and high success rates.
Ensure that the clinic adheres to international standards of care and has accreditation from relevant health authorities. Asking for a detailed treatment plan and understanding the protocols they use can help make an informed decision.

Frequently Asked Questions
What actually happens during hyperstimulation of the ovaries?
The patient will take injectable FSH (follicle stimulating hormone) for eight to eleven days, depending on how long the follicles take to mature. This hormone is produced naturally in a woman’s body causing one egg to develop per cycle. Taking the injectable FSH causes several follicles to develop at once, at approximately the same rate. The development is monitored with vaginal ultrasounds and following the patient’s levels of estradiol and progesterone. FSH brand names include Repronex, Follistim, Menopur, Gonal-F and Bravelle. The patient injects herself daily.
What happens during egg retrieval?
When the follicles have developed enough to be harvested, the patient attends an appointment where she is anesthetized and prepared for the procedure. Next, the doctor uses an ultrasound probe to guide a needle through the vaginal wall and into the follicle of the ovary. The thin needle draws the follicle fluid, which is then examined by an embryologist to find the eggs. The whole process takes about 20 minutes.
What happens to the eggs?
In the next step, the harvested eggs are then fertilized. If the sperm from the potential father, or in some cases, anonymous donor, has normal functionality, the eggs and sperm are placed together in a dish with a nutrient fluid, then incubated overnight to fertilize normally. If the sperm functionality is suboptimal, an embryologist uses Intracytoplasmic Sperm Injection to inject a single sperm into a single egg with an extremely precise glass needle. Once fertilization is complete, the embryos are assessed and prepared to be transferred to the patient’s uterus.
How are the embryos transferred back to the uterus?
The doctor and the patient will discuss the number of embryos to be transferred. The number of successfully fertilized eggs usually determines the number of eggs to be placed in the uterus. Embryos are transferred to the uterus with transabdominal ultrasound guidance. This process does not require anesthesia, but it can cause minor cervical or uterine discomfort. Following transfer, the patient is advised to take at least one days bed rest and two or three additional days of rest, then 10 to 12 days later, two pregnancy tests are scheduled to confirm success. Once two positive tests are completed, an obstetrical ultrasound is ordered to show the sac, fetal pole, yolk sac and fetal heart rate.
Embryoscope©
Built into this technology there is a microscope with a powerful camera that allows the uninterrupted monitoring of the embryo during its first hours of life. In this way, we can keep a close eye on the embryo, from the moment when the oocyte is inseminated and begins to divide into smaller and smaller cells, until it can be transferred to the uterus.
