We presented a 30-year-old man suffering from severe oligozoospermia caused by substantial sperm maturation arrest around the spermatid stage. Additionally, he was suffering from a varicocele. For three years, the couple had been trying to conceive. The clinical and endocrinological evaluation of the woman revealed that she was medically fit to undergo pregnancy. We performed laparoscopic ligation of the spermatic vein to treat the varicocele. Semen analysis was conducted at the beginning of the clinical pregnancy journey and after three and six months of treatment, which included 80 mg/day of phytoestrogens for six months. Six months following the end of the therapy, a second semen analysis was carried out. The inherent characteristics of the semen substantially improved in the third month, facilitating the implementation of the reproductive method referred to as intrauterine insemination. Following this treatment, the patient delivered a healthy baby weighing 3300 g. Sperm parameters improved substantially after three months of therapy; however, they reverted to baseline values during the wash-out period. These promising findings strongly suggest that phytoestrogens could be utilized for therapeutic purposes in the management of oligozoospermia. To further demonstrate the potential impact of phytoestrogens on male infertility, it is imperative to conduct a validation phase and randomized controlled trials.
