میکرواینجکشن یکی از روشهای پیشرفته و دقیق باروری است که به افرادی که با مشکلات ناباروری مواجه هستند، فرصت میدهد شانس بارداری خود را افزایش دهند. In this method, sperm is injected directly into the egg to increase the chance of fertilization. This method is known as a specialized and targeted solution and has been able to bring successful results for many couples. Getting to know the details of this method, the appropriate conditions for its use, and its advantages and limitations, can help make a smarter decision in the path of infertility treatment.

What is microinjection?
Microinjection is an advanced method in the treatment of infertility that is used to increase the chances of conception. In this method, a healthy sperm is directly injected into the egg with the help of a microscope and precise tools to increase the chances of fertilization. This technique is usually used when the quality or number of sperm is low or other methods of artificial insemination are not effective.
The main advantage of this method is very high accuracy and the ability to create fertilization even in situations where conventional IVF methods have little chance. This procedure is performed under completely sterile and controlled conditions and can pave the way to fertility success for many couples.
How is microinjection done?
Microinjection is a precise and step-by-step procedure that is performed using advanced equipment in the laboratory. Its main steps are as follows:
ovarian stimulation
First, the doctor prescribes special hormonal drugs for the woman to stimulate the ovaries and produce several mature eggs at the same time. These drugs cause the ovaries to release more eggs and the chance of successful fertilization increases. During this stage, the doctor regularly monitors the state of the ovaries and the growth of the follicles with ultrasound and hormone tests to determine the best time to harvest the eggs.
egg retrieval
When the eggs are mature enough, the doctor removes the eggs from the ovaries using ultrasound and a very thin needle. The procedure is usually performed under light anesthesia to minimize pain and discomfort. The harvested eggs are immediately transferred to the laboratory to be prepared for the next steps.
sperm preparation
The male sperm sample is examined in the laboratory and the best sperms are separated. If the number or quality of sperm is low, careful sperm selection methods are used to select healthy and active sperm for injection. This stage plays a very important role in increasing the chances of successful conception.
Sperm to egg injection
Using a microscope and very precise instruments, a healthy sperm is injected into each egg. This is the main stage of microinjection and the doctor performs it with high precision to maximize the chance of conception. This process allows the doctor to bypass problems related to sperm quality or movement.
embryo cultivation
At this stage of microinjection, the fertilized eggs, now called embryos, are grown under controlled conditions in the laboratory for several days. During this time, the medical team carefully examines the growth and cell division of the embryos, and the best embryos are selected for transfer.
embryo transfer to the uterus
Healthy embryos are transferred into the woman's uterus with the help of a delicate catheter without causing pain. This step usually does not require anesthesia and is a quick and safe process. After the transfer, the doctor gives the necessary recommendations for taking care of the fetus and preparing the uterus.
follow-up and pregnancy test
A few days after the transfer of the embryo, the doctor checks the condition of the uterus and the embryo. After about two weeks, a pregnancy test is done to determine if the treatment was successful. If needed, additional procedures such as transfer of frozen embryos or additional consultations are performed.
microinjection success percentage
Microinjection is one of the most advanced methods of artificial insemination, and its success rate depends on several factors. The most important factors include the woman's age, egg and sperm quality, fertility history, clinic experience and equipment, and the cause of infertility.
1. Woman's age
A woman's age is one of the most determining factors for the success of this method. With increasing age, the quality and number of eggs decreases and the chance of fertility decreases. In general:
- Women under 35 years: success is about 40 to 50% in each treatment cycle.
- Women aged 35 to 40: success is about 30 to 40%.
- Women over 40: Success drops to 15 to 25% and remains dependent on egg quality.
2. Quality and number of sperm
Microinjection is a suitable option for people with low sperm quality or quantity. Even in cases where the sperm is very weak or abnormal, this method can produce successful fertilization. Low sperm quality may require careful selection of sperm and increase the number of treatment cycles.
3. Egg quality
A healthy, high-quality egg plays a vital role in the success of microinjection. Old or damaged eggs reduce the possibility of fertilization and cell division.
4. Clinic experience and equipment
Clinics that are highly experienced in performing microinjections and use modern equipment usually provide better results. The skill of the medical team in selecting sperm and the technique of direct injection into the egg plays an important role in increasing the chances of success.
5. Medical conditions and fertility history
Some medical problems such as polycystic ovary syndrome, hormonal disorders or a history of repeated miscarriages can reduce the chances of success. Careful examination of medical history and complementary treatments can improve the probability of success.
6. Final success and the birth of a live baby
Even if in vitro fertilization is successful, not all cases result in the birth of a healthy baby. Statistics show that the final success rate of live births is usually slightly lower than the fertility statistics in each cycle.
