testis, cryptorchism, spermogram


aim of the study
Testicular hormonal function and individual fertility potential was examined in cryptorchid men.
material and methods
44 males (mean age 31 year 4.4) operated on due to cryptorchism; group I - 30 with unilateral, group II - 10 with bilateral defect, group III - 4 after orchiectomy. Serum levels of: testosterone, estradiol, FSH, LH, ß-inhibin, spermogram and oval motility index (OMI) were examined.
Normospermia was found in 25, oligospermia in 10 and aspermia in 9 men. Normospermia was observed in 70% of patients of group I, in none of group II and in all instances in group III. The higher position of the testicle, the worse the spermogram was. Sperm cell number in group II was significantly worse than in group I. The OMI values were as follows: I: 18.36 14.85, II: 0.11 0.32, III: 23 10.23. A significant difference between OMI values in patients with abdominal and inguinal testicles was found. The OMI values were higher in patients treated by orchiopexy only compared to men previously treated with HCG surgery (12.32 15.31 vs. 8.81 12.63). 27 (61%) of 44 men remain in relationships declaring the will of having children; I: 19 (63%), II: 6 (60%), III: 2 (50%). 19 (70%) men had children: 16 after unilateral, one after bilateral orchiopexy, and two after orchiectomy.
Bilateral cryptorchidism and primary abdominal testicle position appeared to have deteriorating influence on sperm quality, increasing FSH level and decreasing ß-inhibin serum concentration. The coexistence of both factors in one patient caused amplification of this effect.
