Sexual functioning after treatment for testicular cancer--review and meta-analysis of 36 empirical studies between 1975-2000.

Literature concerning sexual functioning after treatment for testicular cancer from 1975-2000 is reviewed. After a literature search in Medline and Psylit was conducted, as well as a search for cross-references made, a meta-analysis was performed. To describe sexual functioning, several aspects of the sexual response cycle were used: sexual desire, sexual arousal, erection, and orgasm; ejaculatory function, sexual activity, and sexual satisfaction were used as well. The number of patients included in the studies as well as treatment modalities were taken into account. A total of 36 relevant studies was screened (28 retrospective and 7 prospective studies), concerning 2,786 cases of testicular cancer. Meta-analysis revealed that ejaculatory dysfunction was reported most frequently and was related to surgery in the retroperitoneal area. Erectile dysfunction was related to irradiation, but was reported least frequently. Other sexual functions were not related to treatment modality. Meta-analysis revealed no deterioration of sexual functioning in the course of time, except a decrease in sexual desire and an increase in sexual satisfaction. Retrospective studies reported more sexual dysfunction than did prospective studies. Detailed analysis of separate studies, however, revealed a wide variation in reported sexual morbidity, as well as in assessment methods. Somatic consequences of disease and treatment may reduce ejaculation; however, other aspects of sexual functioning are not clearly related to disease- or treatment-related factors and may instead refer to a psychological vulnerability caused by one's confrontation with a life-threatening, genito-urinary disease, such as testicular cancer.

Sexual functioning after multimodality treatment for disseminated nonseminomatous testicular germ cell tumor.

PURPOSE: We determined sexual functioning after chemotherapy for disseminated nonseminomatous testicular germ cell tumor, and evaluated the impact of resection of post-chemotherapy residual retroperitoneal tumor. MATERIALS AND METHODS: A total of 155 consecutive patients treated with chemotherapy for disseminated nonseminomatous testicular germ cell tumor (between 1980 and 1994) was questioned about their sexual functioning. The patients were divided in 2 subgroups: patients treated with or without resection of post-chemotherapy residual retroperitoneal tumor. Volume and location (divided into left para-aortal or right paracaval/interaortacaval) of the resected tumor were related to absence of ejaculation as well as decreased semen amount. In addition, libido, arousal, erection and orgasm were related to ejaculatory dysfunction. RESULTS: A total of 43 patients (27.7%) was treated with chemotherapy only and 112 (72.3%) had additional resection of post-chemotherapy residual retroperitoneal tumor mass. Overall, 22.4% reported loss of libido, 14.1% decreased arousal, 16% erectile dysfunction, 23.1% decreased orgasmic intensity, 17.4% decreased semen amount and 18.7% complete absence of antegrade ejaculation. With exception of absence of ejaculation, sexual dysfunctions were reported in similar frequencies in both treatment subgroups. In the resection of post-chemotherapy residual retroperitoneal tumor subgroup, 25.9% of the patients had complete absence of ejaculation. The other sexual dysfunctions were related neither to decreased semen amount nor to complete absence of ejaculation. The mean volume of resected tumor was higher (95 cm.3) in patients with absence of ejaculation than in those without (40 cm.3), and patients with right paracaval/interaortacaval tumor (20 of 58, 34.5%) reported more often absence of ejaculation than those with left para-aortal tumor (9 of 54, 16.7%). CONCLUSIONS: In patients treated for disseminated nonseminomatous testicular germ cell tumor, post-chemotherapy sexual morbidity cannot be neglected. Except for loss of antegrade ejaculation, sexual dysfunctions are not related to resection of post-chemotherapy residual retroperitoneal mass. A high volume of tumor and a right paracaval/interaortacaval location predispose to loss of antegrade ejaculation.

Sexual functioning after treatment for testicular cancer: comparison of treatment modalities.

BACKGROUND: This retrospective study evaluates changes in sexual functioning after treatment for testicular cancer and investigates whether there is a relationship with different treatment modalities. METHODS: A self-reported questionnaire was sent to 337 men who had been treated for testicular cancer at the University Hospital Groningen between 1977 and 1994. Medical information was obtained from the patient records. RESULTS: A response was received from 287 men (85%); 264 patients were included in this study (78%). The mean patient age at follow-up was 37.7 years (range, 17-71 years). The mean follow-up period was 6.7 years (range, 0.25-18 years). Decrease in sexual functions was reported by 40% of patients (decrease in libido: 19%; arousal: 12% erection: 12.5%; orgasm: 19%; and ejaculation: 26%). Moreover, 23.5% of patients responding reported decreased sexual activity and 12.5% were dissatisfied with their sexual functioning. Patients with Stage II-IV nonseminoma who had been treated with polychemotherapy (PCT) with or without resection of residual retroperitoneal tumor mass (RRRTM) (PCT +/- RRRTM) reported a significantly sharper decrease in sexual functioning than patients who had been followed with a wait-and-see policy (W & S) (Stage I nonseminoma patients). It was noteworthy that patients treated by PCT alone reported more sharply decreased sexual functioning than patients treated by PCT + RRRTM. Patients treated by radiotherapy (Stage I-IIA seminoma) did not report findings significantly different from the W & S group. CONCLUSIONS: Testicular cancer patients are at risk for reduced sexual functioning, especially when treated by chemotherapy, with or without resection of residual tumor. Although chemotherapy may influence somatic aspects of sexual functioning, it appears that psychologic factors arising from the confrontation with testicular cancer play a strongly mediating (if not determining) role.

Sexual dysfunction in nonseminoma testicular cancer patients is related to chemotherapy-induced angiopathy.

PURPOSE: To establish the prevalence of sexual dysfunctions after different treatment modalities for nonseminomatous testicular germ cell tumor (NSTGCT) and to investigate whether treatment-induced angiopathy and neuropathy is related to sexual dysfunction. PATIENTS AND METHODS: A questionnaire assessing sexual dysfunction was sent to 255 NSTGCT survivors. Polychemotherapy (PCT) regimens (cisplatin, vinblastine, and bleomycin [PVB], vinblastine substituted by etoposide [BEP], or cisplatin substituted by carboplatin [CEB], etoposide combined with cisplatin [EP], or with ifosfamide and cisplatin [VIP] were compared regarding treatment-induced angiopathy and neuropathy. Sexual dysfunctions were related to Raynaud's phenomenon and acral paresthesia. RESULTS: Among the 215 responders, 56 (26%) had been treated by orchidectomy and surveillance, 42 (19.6%) by PCT, and 117 (54.4%) by PCT and resection of residual retroperitoneal tumor mass (RRRTM). Overall, loss of libido was reported by 19.1%, decreased arousal by 11.2%, erectile dysfunction by 12.1%, decreased intensity of orgasm by 20%, and ejaculatory problems by 28%. Patients treated with PVB suffered more often from Raynaud's phenomenon compared with those treated with other regimens (40.4% v 29%; P < .05) and from paresthesia (31.6% v 14.7%; P < .05). Patients with Raynaud's phenomenon had more often erectile dysfunction (28.8%) compared with those without (8.4%) (P < .05). CONCLUSION: Compared with orchidectomy alone, PCT, with or without RRRTM, induced more often posttreatment sexual dysfunction. Compared with other chemotherapeutic regimens, signs of angiopathy and neuropathy were most prevalent in those treated with PVB. Erectile dysfunction was related to the chemotherapy-induced Raynaud's phenomenon but not to acral paresthesia.

Sexual functioning in testosterone-supplemented patients treated for bilateral testicular cancer.

OBJECTIVE: To determine the effects of intramuscular injections with testosterone (Sustanon) on sex-hormone levels, sexual functioning and general well-being in patients treated with orchidectomy for bilateral testicular cancer. PATIENTS AND METHODS: The study comprised seven men (median age 38 years, range 25-46) who had undergone orchidectomy for bilateral testicular cancer. Patients received intramuscular injections with testosterone every 3 weeks and blood samples for hormone analysis were collected from each patient at three times: one day after testosterone injection (t1), halfway between subsequent injections (t2) and just before injection (t3). Plasma hormone levels were then related to sexual function, as assessed by self-reported data on sexuality and general well-being, measurements of nocturnal penile tumescence and rigidity (NPTR) and erectile function elicited by visual erotic stimulation (VES), determined at t1, t2 and t3. RESULTS: During the 3-week interval between injections, there was a sixfold decrease in plasma testosterone level (mean testosterone 35.8, SD 7.8, and 6.0, SD 2.5 nmol/L, at t1 and t3, respectively). At t1, five of the men had a plasma testosterone level above the upper normal limit (> 35 nmol/L) and at t2 and t3, testosterone levels were below the reference range (< 10 nmol/L) in three and six men, respectively. Oestradiol (E2) levels showed the same pattern: at t1 the mean (SD) E2 level was 0.17 (0.07) nmol/L and at t3 0.07 (0.01) nmol/L. In contrast to follicle-stimulating hormone, luteinizing hormone (LH) mirrored the decline in plasma testosterone after injection, with the lowest levels at t1 and the highest at t3. Other hormone levels remained unchanged. Three patients reported loss of libido, decreased arousal, erectile dysfunction, fatigue and mood depression. However, neither the arousal nor the erectile problems could be verified by VES. There was no relationship between plasma testosterone levels, the reported sexual dysfunctions and the results of NPTR and VES measurements. Although unrelated to a specific testosterone level, three patients reported increased irritability, excessive sweating, hot flushes and heat intolerance at the end of the injection interval. These adverse effects of declining plasma testosterone were related to loss of libido and other sexual problems. CONCLUSION: In most patients castrated for bilateral testicular cancer and receiving intramuscular injections with testosterone, plasma testosterone levels were outside the normal range. After injection, there was a rapid decline of plasma testosterone to levels below the lower normal limit. With the exception of oestradiol, sex-hormone levels were not correlated to testosterone levels. Sexual functioning was not affected by the fluctuations of plasma testosterone level. However, at the end of the injection interval, adverse psychological and physical effects had a significant impact on libido and arousal.
