Objective      To explore whether there is negative influence of hip arthroplasty on the male sexual function.       Methods      A total of 76 male patients under going hip arthroplasty in our hospital from September 2011 to September 2013 were enrolled in this study and  divided into a young group (12 cases

15.8%

20 to 39 years old)

a middle-age group (40 cases

52.6%

40 to 59 years old)

and an elderly group (24 cases

21.3%

60 years old and above). The hip joint function and the sexual function were surveyed using the hip joint function score (Harris)

anxiety and depression self rating scale (SAS/SDS)

the 5-item version of the international index of erectile function questionnaire (IIEF-5)

Chinese patients with premature ejaculation function evaluation questionnaire (CIPE)

and visual analogue scale (VAS) before surgery and in 6 and 12 months after surgery

and the relationship between the hip arthroplasty and the male sexual function was further analyzed.       Results      All the 76 cases accomplished the follow-up lasting for 12-15 months

with an average of 13.2±1.4 months. During the  follow-up

the blood vessels

nerve

recurrent fractures and other related complications were not found. There were 8 cases (33.3%) in the elderly group and 5 cases (12.5%) in the middle age group

with different degrees of decline sexual function including erectile function

orgasm

sexual desire

sexual satis faction and overall satisfaction in 6 months after surgery. The CIPE  score in the elderly group declined from 31.19±4.11 points to 28.08±3.54 points

and the IIEF score was declined from 17.15±4.13 points to 14.13±8.22 points. The CIPE score in the middle age group was declined from 33.17±2.13 points to 30.09±3.41 points

and the IIEF score declined from 21.45±2.12 points to 19.11±7.43 points. In addition

the sexual function was negatively correlated with the postoperative SAS/SDS and CAS scores (r=0.681

0.723

0.751

0.694

0.751

and 0.728

P0.05). There were significant differences in the scores before and in 6 and 12 months after surgery (P0.05). The patients were restored to the preoperative levels after 12 months

and the rest of the patients had no any obvious change.       Conclusion      Some middle-aged or elderly patients have a decrease in sexual function in 6 months after hip joint replacement. The alleviation of pain

anxiety and depression is helpful to restore the male sexual function as soon as possible.
