Cryptorchidism and Fertility.

Area of Science:

• Pediatric endocrinology
• Reproductive medicine
• Urology

Background:

• Cryptorchidism, or undescended testes, affects 2.4%-5% of newborns.
• About 23% of cases require surgical intervention (orchidopexy) for testicular descent.
• Men with bilateral cryptorchidism have a sixfold increased risk of infertility.

Purpose of the Study:

• To summarize the incidence and implications of cryptorchidism.
• To explore the link between cryptorchidism history and male infertility.
• To identify factors contributing to infertility post-orchidopexy.

Main Methods:

• Literature review of cryptorchidism prevalence.
• Analysis of infertility rates in relation to cryptorchidism and orchidopexy.
• Identification of etiological factors for infertility in treated cryptorchidism.

Main Results:

• Cryptorchidism is a significant risk factor for male infertility.
• Approximately 10% of infertile men report a history of cryptorchidism and orchidopexy.
• Testicular maldevelopment, hyperthermia, and antisperm antibodies are key contributors to infertility.

Conclusions:

• Undescended testes pose a substantial risk for male infertility.
• Orchidopexy may not fully restore fertility due to underlying testicular issues.
• Further research into optimizing fertility outcomes for cryptorchidism patients is warranted.
