Male infertility and androgen replacement therapy for subjects with bilateral testicular tumors

Area of Science:

• Oncology
• Andrology
• Reproductive Medicine

Background:

• Bilateral testicular tumors present unique challenges for oncological and andrological management.
• Understanding the long-term sequelae, including infertility and hormone deficiency, is crucial for patient care.

Purpose of the Study:

• To investigate andrological outcomes, specifically male infertility and androgen deficiency, following treatment for bilateral testicular tumors.
• To evaluate the safety and efficacy of androgen replacement therapy (ART) in this patient population.

Main Methods:

• Clinical analysis of five subjects with bilateral testicular cancer treated between 1996 and 2013.
• Assessment included histological diagnosis, treatment modalities (bilateral orchiectomy, chemotherapy, radiation, surgery), and long-term follow-up.
• Evaluation of reproductive status and androgen levels, with ART initiated for testosterone deficiency.

Main Results:

• The mean age at initial treatment was 29.4 years; bilateral seminoma or mixed germ cell tumors were diagnosed.
• All subjects underwent bilateral orchiectomy; no tumor recurrence was observed over 5-34 years.
• Four subjects received ART, which alleviated symptoms of testosterone deficiency without adverse events. Reproductive outcomes varied, with limited success in achieving fertility post-treatment.

Conclusions:

• Androgen replacement therapy is safe and effective for managing androgen deficiency symptoms in patients with a history of bilateral testicular tumors.
• Male infertility remains a significant challenge post-treatment, indicating a need for more aggressive fertility-preserving strategies or advanced reproductive interventions.
