Blog Post: The Impact of Male Factor Infertility on Gamete Intrafallopian Transfer
Infertility affects approximately 12% of couples worldwide, and it is estimated that male factor infertility accounts for 30-40% of these cases. While there are various assisted reproductive techniques available to help couples conceive, one of the options that has gained popularity over the years is Gamete Intrafallopian Transfer (GIFT). However, the presence of male factor infertility can significantly impact the success of GIFT, making it essential to understand the role of male infertility in this procedure.
What is Gamete Intrafallopian Transfer (GIFT)?
GIFT is an assisted reproductive technique that involves transferring a mixture of sperm and eggs (gametes) directly into the fallopian tubes. This procedure is similar to in vitro fertilization (IVF) in that it also involves fertilizing the eggs outside the body. However, in GIFT, the fertilization takes place inside the woman’s body, while in IVF, the fertilized eggs are transferred to the uterus. This technique was first introduced in the late 1970s and has been used as an alternative to IVF in cases where the woman has a patent fallopian tube.
The Role of Male Factor Infertility in GIFT
Male factor infertility refers to the inability of a man to impregnate a woman due to problems with his sperm. This can include low sperm count, poor sperm motility, or abnormal sperm morphology. In GIFT, the quality and quantity of sperm play a crucial role in the success of the procedure. The sperm must be able to fertilize the egg successfully, and the sperm count must be sufficient to achieve fertilization.
Impact of Low Sperm Count on GIFT
One of the primary causes of male factor infertility is a low sperm count. This means that there are fewer sperm available for fertilization, which can significantly impact the success rate of GIFT. In this procedure, a mixture of sperm and eggs is transferred to the fallopian tubes, and the sperm must travel through the tubes to reach the eggs. If the sperm count is low, there may not be enough sperm to reach and fertilize the eggs, resulting in a failed GIFT procedure.
Poor Sperm Motility and GIFT

Sperm motility refers to the ability of sperm to move and swim towards the egg. In GIFT, the sperm must have good motility to reach and fertilize the egg successfully. If the sperm have poor motility, they may not be able to reach the egg, leading to a failed GIFT procedure. Poor sperm motility is a common issue in male factor infertility, and it can be caused by various factors such as hormonal imbalances, genetic defects, or infections.
Abnormal Sperm Morphology and GIFT
Abnormal sperm morphology refers to the shape and size of the sperm. In GIFT, the sperm must have a normal shape and size to be able to fertilize the egg successfully. If the sperm have abnormal morphology, they may not be able to penetrate the egg, resulting in a failed GIFT procedure. Abnormal sperm morphology can be caused by genetic defects, hormonal imbalances, or lifestyle factors such as smoking or excessive alcohol consumption.
Addressing Male Factor Infertility in GIFT
The presence of male factor infertility can significantly impact the success rate of GIFT. However, there are steps that can be taken to address this issue and increase the chances of a successful GIFT procedure. One of the options is to use donor sperm, where healthy and viable sperm from a sperm bank are used for fertilization. This eliminates the potential issues caused by male factor infertility and increases the chances of a successful pregnancy.
Another option is to undergo sperm retrieval procedures such as testicular sperm extraction (TESE) or percutaneous epididymal sperm aspiration (PESA). These procedures involve extracting sperm directly from the testicles or epididymis and can be used in cases where the man has a blockage in his reproductive system, leading to infertility. The retrieved sperm can then be used in the GIFT procedure, increasing the chances of success.
Conclusion
GIFT can be an effective assisted reproductive technique for couples struggling with infertility. However, the presence of male factor infertility can significantly impact the success rate of this procedure. It is essential to address any issues with sperm count, motility, or morphology before undergoing GIFT to increase the chances of a successful pregnancy. With advancements in technology and medical procedures, there are various options available to overcome male factor infertility and achieve a successful GIFT procedure.
In summary, male factor infertility can have a significant impact on the success of Gamete Intrafallopian Transfer (GIFT). It is crucial to address any issues with sperm count, motility, or morphology before undergoing this procedure. Options such as using donor sperm or sperm retrieval procedures can help increase the chances of a successful GIFT procedure and help couples achieve their dream of starting a family.
