Testicular torsion is a medical emergency that occurs when the spermatic cord, which provides blood flow to the testicle, twists and cuts off the blood supply. This condition demands immediate attention due to the risk of permanent damage to the testicle and subsequent complications, including infertility. Testicular torsion primarily affects males in their teenage years but can occur at any age. The urgency of this condition cannot be overstated, as the window for effective treatment to preserve testicular function and fertility is extremely narrow.
The potential impact of testicular torsion on male fertility is significant. Damage to the testicle can result in impaired sperm production, reduced testosterone levels, and long-term fertility issues. Understanding how testicular torsion affects fertility and the importance of prompt medical intervention is crucial for preserving reproductive health.
How Testicular Torsion Affects Fertility
Testicular torsion occurs when the spermatic cord twists, cutting off blood flow to the testicle. The testicles require a constant supply of oxygen-rich blood to function properly, and this blood flow is critical for the survival of the cells responsible for producing sperm and testosterone. When blood flow is interrupted, it can lead to ischemia and subsequent testicular damage.

Blood Flow Interruption and Cellular Damage
The primary consequence of testicular torsion is the interruption of blood flow, which deprives the testicle of oxygen and essential nutrients. This condition can cause significant damage to the seminiferous tubules, where sperm production occurs. Without adequate blood supply, these cells can suffer irreversible damage, leading to a decrease in sperm production.
Damage to Sperm-Producing Cells
The seminiferous tubules contain Sertoli cells and germ cells, which are crucial for spermatogenesis, the process of sperm production. Ischemia caused by testicular torsion can lead to apoptosis (cell death) of these cells. As a result, the overall sperm count can be significantly reduced, impacting fertility. Additionally, surviving cells may produce sperm that are abnormal in shape (morphology) or have reduced motility, further diminishing the chances of successful fertilization.
Low Testosterone Levels
The Leydig cells in the testicles are responsible for producing testosterone, the hormone critical for male reproductive health and secondary sexual characteristics. Testicular torsion can damage these cells, leading to a decrease in testosterone levels. Low testosterone can affect libido, erectile function, and overall fertility. Chronic low testosterone levels can also have broader health implications, including reduced muscle mass, increased body fat, and decreased bone density.
Impact on Sperm Quality
Research has shown that testicular torsion can have a profound impact on sperm quality, affecting motility, morphology, and count. Studies examining semen samples from men who have experienced testicular torsion reveal a significant decrease in sperm quality compared to those without such a history.
Sperm Motility
Sperm motility refers to the ability of sperm to move effectively towards an egg. Poor motility can hinder the sperm’s ability to reach and fertilize the egg, reducing the likelihood of conception. Testicular torsion can lead to a substantial reduction in the percentage of motile sperm, making natural conception more challenging.
Sperm Morphology
Normal sperm morphology is essential for the sperm to penetrate and fertilize the egg. Abnormalities in sperm shape can impair this function. Testicular torsion can increase the incidence of sperm with abnormal morphology, which may affect the overall fertility potential of affected individuals.
Sperm Count
Sperm count is another critical factor in male fertility. A low sperm count can significantly reduce the chances of successful fertilization. Studies have shown that men who have experienced testicular torsion often have lower sperm counts compared to those who have not, further contributing to fertility challenges.
Subfertility
The combination of reduced sperm motility, abnormal morphology, and lower sperm count often results in subfertility, a condition characterized by a reduced ability to conceive naturally. Men who have had testicular torsion may find it more difficult to father children, although they are not necessarily infertile. Assisted reproductive technologies, such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), may be required to achieve pregnancy.
Time as a Critical Factor
The timing of medical intervention is crucial in cases of testicular torsion. The longer the testicle remains twisted, the greater the risk of permanent damage and subsequent fertility issues. Prompt treatment significantly improves the chances of preserving testicular function and fertility.

Importance of Immediate Medical Attention
Testicular torsion is a surgical emergency. If you experience sudden, severe testicular pain, it is essential to seek medical attention immediately. Delay in treatment can lead to testicular necrosis, where the tissue dies due to lack of blood flow. The sooner the condition is addressed, the better the chances of saving the testicle and maintaining normal fertility.
Surgical Treatment and Outcomes
The primary treatment for testicular torsion is surgical intervention, typically performed through a procedure called orchiopexy. During this surgery, the twisted spermatic cord is untwisted, and the testicle is secured to prevent future torsion. If the testicle is found to be non-viable due to prolonged lack of blood flow, it may need to be removed (orchiectomy).
Studies indicate that if surgery is performed within six hours of the onset of symptoms, the chances of preserving the testicle and its function are high. Delays beyond this period significantly decrease the likelihood of testicular salvage and increase the risk of long-term fertility issues.
Conclusion
Testicular torsion poses a serious risk to male fertility. The condition’s impact on sperm-producing cells, testosterone levels, and overall sperm quality can lead to significant fertility challenges. Prompt medical intervention is crucial to minimize testicular damage and preserve fertility.
Treatment for testicular torsion typically involves surgical correction, and the timing of this surgery is critical. Immediate medical attention can make the difference between preserving and losing testicular function. For any concerns regarding testicular pain or fertility, consulting a urologist is essential.
By understanding the risks and seeking prompt treatment, men can take proactive steps to protect their reproductive health and preserve their fertility.
