Splenogonadal fusion (SGF) is a rare congenital malformation. Since it lacks characteristic features, very few cases of SGF have been diagnosed preoperatively. Laparoscopy was effective in both diagnosing and surgically treating this condition. Herein, we reported left side SGF in a male patient who was diagnosed during laparoscopic exploration, and Fowler-Stephens orchidopexy was implemented at the same time. The patient was followed up for one year. At a 6-month follow-up, the left scrotum demonstrated swelling and the internal contents were hard. An ultrasound of this testicle indicated non-uniform, splenic-like organization. However, at the one-year follow-up, the volume of splenic-like organization was reduced but the testicular size did not exhibit further atrophy.
