Cryptorchidism: Follow-up
Updated: Jan 2, 2009
Outcome and Prognosis
Success rates of medical or surgical orchiopexy are addressed in Treatment.
Future and Controversies
Testis cancer
Giwercman et al recommend biopsy of all cryptorchid testes in adults. If carcinoma in situ (CIS) is present, they recommend contralateral biopsy and unilateral orchiectomy. If the remaining contralateral testis also harbors CIS, they recommend radiation therapy.55
Lenz et al demonstrated an abnormal echo pattern in 3% of postpubertal testes that had undergone orchiopexy. This abnormal ultrasonographic finding may be associated with CIS, and they suggest offering scrotal ultrasonography to postpubertal patients.56
Infertility
Based on retrospective human data and orchiopexy studies in rats, Bellinger et al believe that the practice of transparenchymal sutures to fixate the testis or the use of scrotal wall bolsters put the testis at significant risk for direct trauma. Suture violation of the blood-testis barrier may also play a role in future antisperm antibody development. Further investigation is necessary to fully define this concept of testicular injury.50
Studies have shown that patients with a fertility index of less than 0.2 based on testis biopsy at orchiopexy are at a severe risk for later infertility, and these counts correlate with sperm density in adulthood. Hadziselimovic et al (1997) suggested that such patients may benefit from adjuvant hormonal therapy with resultant increased numbers of germ cells later in life.57 LHRH agonists may improve testicular germ cell and postpubertal sperm counts. Huff et al (2001) showed that 75% of boys with significantly reduced germ cell counts who were treated with nafarelin after orchiopexy and bilateral testicular biopsy showed a significant improvement in total germ cell counts on rebiopsy after 5 months.26 Neoadjuvant GnRH in prepubescent boys may also positively affect future fertility, with the highest fertility indices reported with therapy before age 2 years.58
FutureSchneck et al reported a trend of significantly lower inhibin B levels in boys with cryptorchidism compared with age-matched controls. Inhibin B is produced by the Sertoli cells and is an important regulator of FSH secretion. Kawada et al demonstrated that adult patients who previously had cryptorchidism and markedly low inhibin levels and elevated FSH levels had severely compromised sperm production.59
Kolon et al demonstrated mutations in the developmental homeobox gene, HOXA10, in boys with cryptorchidism and polymorphisms in patients with cryptorchidism and in the general population.60 Analysis of paralogous and orthologous genes of HOXA10 will help elucidate the role of regulatory genes in normal and abnormal testicular descent. Several authors have examined the role of various gene alterations in humans; however, despite findings in animal models, no human isolated cryptorchidism gene has yet been identified. This further supports the notion that the etiology of cryptorchidism is multifactorial.
Further evaluation is needed to identify the role, if any, of isolated cryptorchidism in the spectrum of intersexuality. Histologic, molecular, radiologic, and hormonal studies may reveal similar or dissimilar etiologies for the common isolated undescended testis compared with the relatively uncommon ambiguous genitalia of intersexuality.
