The historical roots of Intrauterine Insemination (IUI) trace back to the pioneering efforts of John Hunter in 1770, who advised a man with hypospadias to collect semen in a syringe for injection into his wife, resulting in a successful pregnancy. Centuries later, Arabs practiced artificial insemination over 600 years ago, demonstrating its longstanding presence in various cultures.
In 1765, Jacobi of Germany achieved artificial insemination success with fish eggs, while Lazzaro Spallanzani, an Italian biologist, conducted a seminal experiment in 1789 by inseminating a female dog with collected semen, yielding healthy pups.
IUI's historical evolution continued in the realm of agriculture, with dairy farmers using modern insemination techniques to enhance cattle breeding. However, it wasn't until the advent of in vitro fertilization (IVF) that interest in IUI was rekindled. As science progressed, understanding of sperm physiology improved, leading to advancements in sperm processing techniques.
Today, IUI stands as a cornerstone of fertility treatments, bridging historical roots with contemporary innovations. The journey from early experiments to current techniques highlights the resilience and adaptability of artificial insemination, making it a widely used and accessible method in the global pursuit of fertility solutions.
