Abstract
Most genitourinary tract cancers have a negative impact on male fertility. Although testicular cancers have the worst impact, other tumors such as prostate, bladder, and penis are diagnosed early and treated in relatively younger patients in which couple fertility can be an important concern. The purpose of this review is to highlight both the pathogenetic mechanisms of damage to male fertility in the context of the main urological cancers and the methods of preserving male fertility in an oncological setting, in light of the most recent scientific evidence. A systematic review of available literature was carried out on the main scientific search engines, such as PubMed, Clinicaltrials.Gov, and Google scholar. Three hundred twenty-five relevant articles on this subject were identified, 98 of which were selected being the most relevant to the purpose of this review. There is a strong evidence in literature that all of the genitourinary oncological therapies have a deep negative impact on male fertility: orchiectomy, partial orchiectomy, retroperitoneal lymphadenectomy (RPLND), radical cystectomy, prostatectomy, penectomy, as well as radiotherapy, chemotherapy, and hormonal androgen suppression. Preservation of fertility is possible and includes cryopreservation, hormonal manipulation with GnRH analogs before chemotherapy, androgen replacement. Germ cell auto transplantation is an intriguing strategy with future perspectives. Careful evaluation of male fertility must be a key point before treating genitourinary tumors, taking into account patients' age and couples' perspectives. Informed consent should provide adequate information to the patient about the current state of his fertility and about the balance between risks and benefits in oncological terms. Standard approaches to genitourinary tumors should include a multidisciplinary team with urologists, oncologists, radiotherapists, psycho-sexologists, andrologists, gynecologists, and reproductive endocrinologists.

Abstract
Spermatogenesis is an androgen-regulated process that depends on the action of androgen receptor (AR). Sperm production may be affected in men treated for testicular cancer (TC), and it is important to identify the factors influencing the timing of spermatogenesis recovery following cancer treatment. It is known that the CAG and GGN repeat numbers affect the activity of the AR; therefore, the aim of this study is to investigate if the CAG and GGN polymorphisms in the AR gene predict recovery of sperm production after TC treatment. TC patients (n = 130) delivered ejaculates at the following time points: postorchiectomy and at 6, 12, 24, 36, and 60 months posttherapy (T0, T6, T12, T24, T36, and T60). The CAG lengths were categorized into three groups, <22 CAG, 22–23 CAG, and >23 CAG, and the GGN tracts were also categorized into three groups, <23 GGN, 23 GGN, and >23 GGN. At T12, men with 22–23 CAG presented with a statistically significantly (P = 0.045) lower sperm concentration than those with other CAG numbers (8.4 × 106 ml−1vs 16 × 106 ml−1; 95% CI: 1.01–2.65). This association was robust to omitting adjustment for treatment type and sperm concentration at T0 (P = 0.021; 3.7 × 106 ml−1vs 10 × 106 ml−1; 95% CI: 1.13–4.90). The same trends were observed for total sperm number. The least active AR variant seems to be associated with a more rapid recovery of spermatogenesis. This finding adds to our understanding of the biology of postcancer therapy recovery of fertility in males and has clinical implications.

Abstract
Purpose. Infertility as a late complication of cancer chemotherapy, focusing on specific drug-related ef fects, effects observed in the treatment of certain malignancies, and strategies for prevention is re viewed. Data Sources. A MEDLINE search of articles from 1966 to present was conducted using the terms infertility, antineoplastics, amenorrhea, azospermia, oogenesis, and spermatogenesis. Additional refer ences were identified using review articles and phar macology textbooks. Study Selection. All human studies reported in English language were included. Animal studies were included when human data were insufficient or un available. Data Synthesis. Data on the infertility effects of individual antineoplastic agents are difficult to inter pret for several reasons, including small sample sizes, lack of prechemotherapy fertility assessment, inade quate long-term follow-up, and use of regimens in cluding multiple agents. In general, the incidence and severity of antifertility effects are dependent on the total dosage delivered, duration of therapy, and age at exposure. The alkylating agents have the most signif icant effects on fertility. Fertility outcomes have been reported for several different malignancies, especially in patients cured of Hodgkin's disease and testicular cancer. Information on specific antineoplastic agents and cancers are reviewed. Several methods have been employed to decrease gonadotoxic effects, but none have been effective. Conclusions. Infertility is a common late com plication of cancer chemotherapy that is receiving increasing attention as the number of cancer survi vors increases. Health care professionals should be aware of infertility risks associated with antineoplastic agents and certain malignancies, and patients should be informed of these risks as treatment decisions are made.

Abstract
With advances in cancer treatment, more pediatric cancer patients have increased their life expectancy. Because cancer-related therapy causes various physical and psychological problems, many male survivors experience later problems with thyroid and sexual functions, and with growth. As outcomes have improved, more survivors need to maintain their reproductive function to maximize their long-term quality of life. Cancer and cancer-related treatment can impair fertility by damage to the testes, to the hypothalamic-pituitary-gonadal axis, or to the genitourinary organs. Prior radiation therapy to the testes, the use of alkylating agents, and central hypogonadism further impair fertility in male survivors of childhood cancer. Following any course of chemotherapy, peripubertal maturation, any testicular volume changes, and symptoms of androgen deficiency should be monitored systematically. If patients request fertility testing, spermatogenesis status can be evaluated either directly by semen analysis or indirectly by determination of the levels of testosterone/gonadotropins and by monitoring any changes in testicular volume. According to the patient's condition, semen cryopreservation, hormonal therapy, or assisted reproduction technologies should be provided.

Abstract
Childhood cancer survivors (CCS) have an increased risk of impaired spermatogenesis, but data regarding the disease- and treatment-related risk factors of azoospermia are scarce. Such information is crucial both for counselling CCS and for selecting patients for testicular tissue cryopreservation. The proportion of azoospermic men in CCS was 18% [95% confidence interval (CI): 12-26], specifically for leukaemias (19%; 95% CI: 5.5-42), Hodgkin's disease (53%; 95% CI: 29-76), non-Hodgkin's lymphoma (11%; 95% CI: 0.28-48) and testicular cancer (11%; 95% CI: 0.28-48). In CCS treated with high doses of alkylating agents, the proportion of azoospermic men was 80% (95% CI: 28-99) and if radiotherapy was used additionally, the proportion was 64% (95% CI: 35-87). In CCS with subnormal Inhibin B levels, the proportion of azoospermic men was 66% (95% CI: 47-81) and for those with elevated follicle-stimulating hormone (FSH) levels, the proportion was 50% (95% CI: 35-67). Among CCS with subnormal testicular volume (≤ 24 mL), azoospermia was found in 61% (95% CI: 39-80) of the cases. Most childhood cancer diagnoses are associated with an increased risk of azoospermia, especially in CCS receiving testicular irradiation, high doses of alkylating drugs and other types of cytotoxic treatment, if combined with irradiation. Inhibin B, FSH and testicular volume can be used as predictors for the risk of azoospermia.

Abstract
Cancer treatment with chemotherapy or radiotherapy causes gonadal toxicity in male patients. The endpoint of most concern for future reproductive options is the induction of prolonged azoospermia, which may or may not be reversible. The immediate effects of therapy and its reversibility are most readily observed in post-pubertal patients, but the same antineoplastic regimens given to prepubertal males can induce permanent azoospermia. The probability of permanent azoospermia is related to the specific agents used and their doses. The most damaging are alkylating agents (particularly chlorambucil, procarbazine, cyclophosphamide, melphalan, and busulfan), cisplatin and radiation to the region of the testicles.

Abstract
Cisplatin is a potent drug used in clinical oncology but causes spermatogenesis damage. Amifostine is a drug used against toxicity caused by ionizing irradiation and chemotherapeutic drugs. Since cisplatin provokes fertility and induces germ cell apoptosis and necrosis, we proposed to evaluate the amifostine cytoprotective action on testes of cisplatin-treated rats. Thirty-day-old prepubertal Wistar rats received a single cisplatin dose of 5 mg/kg and were killed after 3, 6, and 12 hr. The hematoxylin-eosin stained testicular sections were submitted to histological, morphometric, and stereological analysis. The terminal deoxynucleotidyl transferase-mediated deoxyuridinetriphosphate nick end-labeling (TUNEL) method was used to label apoptotic cells. TUNEL-positive and TUNEL-negative germ cells with abnormal nuclear morphology (ANM) were scored. Significant alterations of greater part of the parameters occurred in the cisplatin-treated group (CE) compared to the group that received amifostine before the cisplatin-treatment (ACE); however, testicular weight and volume did not vary between these groups. Tubular diameter was reduced in CE in comparison to ACE rats, while interstitial tissue and lymphatic space volume and volume density were significantly higher in CE rats; interstitial testicular edema probably occurred in cisplatin-treated rats. CE rats showed important histological alterations, which were more accentuated than in ACE rats. The numerical densities of apoptotic germ cells and TUNEL-negative cells with ANM were lower in ACE than in CE rats. In conclusion, the amifostine previously administered to prepubertal rats reduced the testicular damage caused by cisplatin. We conclude that amifostine partially protected the rat seminiferous epithelium against cisplatin toxicity.

Abstract
Testicular cancer is a malignancy for which an interdisciplinary approach offers the highest likelihood of cure. In many patients, both chemotherapy and surgery play a prominent role in their care. Although cure can be achieved in a majority of patients, the treatment can occasionally leave the patient with late sequelae. This article discusses the long-term toxicity of curative surgical or cytotoxic therapy for germ cell tumors.

Abstract
OBJECTIVE To investigate the impact of bleomycin-etoposide-carboplatin combination chemotherapy on long-term fertility in patients with testicular germ cell tumors. METHODS Twenty-five patients with high risk stage I and IM non-seminomatous germ cell tumors (NSGCT, Group A) and 44 with advanced seminoma or NSGCT (Group B) were treated with bleomycin 30 mg (days 2, 9, 16), etoposide 165 mg/m(2) (days 1-3) and carboplatin 400mg/m(2) or AUC 5 (day 1) (BEC(90)). Treatment was repeated every 3 weeks. Group A patients received 2 cycles of BEC(90), while Group B ones received 4 to 5 cycles of BEC(90). Sperm count and hormonal analyses were examined pre- and post-chemotherapy. Counts were classified as normospermia (NS) if >20 x 10(6)ml(-1), oligospermia (OS) if 1-20 x 10(6)ml(-1) and azoospermia (AS) if <1 x 10(6)ml(-1). RESULTS Patients were followed for a median of 2.9 years post-chemotherapy. The post-orchidectomy median luteinizing hormone (LH) serum levels were slightly above the upper normal limit while the serum levels of follicle stimulating hormone (FSH) and testosterone (T) were within the reference interval. Thirty-eight (55%) patients had NS pre-chemotherapy. None of the 14 NS patients who received 2 cycles of BEC(90) had AS post-chemotherapy, while only 1 of the 24 NS patients who were treated with > or =4 cycles of BEC(90) had AS post-treatment. Among the NS patients, 93% and 83%, respectively, remained NS following chemotherapy. Overall, 90% of patients had recovery (61% NS, 29% OS) of spermatogenesis after treatment. The median FSH serum values were significantly elevated at least 1-year post-chemotherapy when compared with the pre-treatment levels. Eighteen months post-chemotherapy the median FSH values had returned to the reference limits. Serum LH and T levels were unaffected by treatment. The pre-treatment sperm count and the bulk of disease were significantly associated with recovery of spermatogenesis. No association was found between recovery of spermatogenesis and 2 or > or =4 cycles of chemotherapy, age > or =30 years and post-chemotherapy lymph node dissection. Thirteen patients (4 with OS) fathered 16 children. No congenital abnormalities occurred in any of these children. CONCLUSION The BEC(90) regimen has no major effect on fertility and Leydig cell function. However, carboplatin-based chemotherapy has been proved less effective than cisplatin-based chemotherapy and is not currently used in the treatment of testicular cancer.

Abstract
An increasing proportion of boys and young men with cancer will survive their disease and desire fertility. Unfortunately, the cancer treatment, and in some cases the malignant disease itself, may have a negative and permanent impact on the individual's fertility potential. This effect is highly dependent on the type and dose of therapy as well as the age at which it has been given. Basic knowledge in this field is necessary to enable oncologists and fertility specialists to counsel these patients about their fertility prospects and, if appropriate, advise them to take precautions (e.g. the cryopreservation of semen) to safeguard their fertility. Another aspect of the relationship between cancer and infertility is the possibility that men with testicular dysfunction may have an increased risk of testicular cancer. Screening for early testicular malignancy may therefore be advisable in some groups of men with poor semen quality.

Abstract
Germ cell tumours, even at an advanced stage, represent a unique model of malignant curable disease since >80% of patients are expected to be cured after appropriate therapy: surgery and radiotherapy in early stages, and chemotherapy and surgery in advanced stages. In advanced stages, serum tumour marker levels as well as extrapulmonary (brain, liver and bone) visceral metastases are the most important prognostic factors that affect treatment modalities. 'Gold standard' regimens for germ cell cancer currently include etoposide plus cisplatin with (BEP) or without (EP) bleomycin. In patients with good risk disease (90% cure rate), the optimal regimen of chemotherapy should combine the best efficacy and the least toxicity. As a result of randomised trials, 3 regimens can be currently recommended: (i) 4 cycles of EP; (ii) 4 cycles of BEP (with etoposide 350 mg/m2 per cycle); or (iii) 3 cycles of BEP (with etoposide 500 mg/m2 per cycle). In patients with poor risk disease, 4 cycles of BEP (with etoposide 500 mg/m2 per cycle) allow a disappointing cure rate of 50%. The long term toxicity of these regimens (gonadal toxicity and secondary malignancies) appears to be negligible and clearly does not challenge current standard strategies.

Abstract
BACKGROUND The prognosis of advanced testicular cancer has improved considerably after the introduction of cisplatin-based combination chemotherapy. The improved prognosis of testicular cancer has brought the long-term toxicity of the treatment into focus. PATIENTS AND METHODS Long-term toxicity was investigated prospectively until more than 10 years after after treatment in a group of 22 patients treated with six series of cisplatin based chemotherapy (PVB) for testicular cancer. We have focused on nephro-, neuro-, pulmonary-, and gonadal toxicity. RESULTS Glomerular filtration rate (GFR) decreased significantly during treatment but increased during follow-up and all the patients had normal values of GFR 10-15 years after treatment. Carbon monoxide diffusion capacity (TLco) decreased during PVB treatment in smokers. TLco remained unchanged during the first years after PVB treatment, but improvement of TLco was seen in some patients more than 43 months after treatment. Paresthesia was reported by 83% of the patients immediately after treatment, 50% at follow-up 4-9 years after chemotherapy and 14% prevalence 11-15 hears after treatment. The reported decline in neurotoxicity was verified by normalisation of vibration perception. Gonadal toxicity was severe and persistent although improvement was seen in a few patients even many years after treatment. CONCLUSIONS The patients treated with PVB were physically and socially well-being at follow-up investigation 11-15 years after treatment. Improvements in pulmonary- and renal function, and recovery from neurotoxicity was seen during the long-term follow-up period. Gonadal toxicity was severe and persistent.

Abstract
OBJECTIVE To determine whether the treatment of patients with testicular cancer, using cisplatin combined with etoposide and bleomycin (BEP) after orchidectomy in those with disseminated disease, causes changes in sex hormones and penile vascularization, possibly related to sexual dysfunction. PATIENTS AND METHODS Ten patients treated with BEP were compared with 11 undergoing orchidectomy alone followed by surveillance. Sex hormone levels were analysed and cavernosal artery duplex ultrasonography performed before orchidectomy and at 6 and 12 months afterward. Patients were questioned about their sexual function. After 1 year, a visual erotic stimulation (VES) test was performed to assess penile rigidity. RESULTS In contrast to the surveillance group, BEP-treated patients had higher follicle-stimulating hormone (4.6 vs 26.5 U/L) and luteinizing hormone (1.4 vs 8.2 U/L) levels, and lower testosterone levels (21.1 vs 14.7 nmol/L) at 6 months than at baseline. At 1 year, most patients had compensated hypergonadotrophic eugonadism, but Leydig cell function had recovered. Changes in cavernosal artery peak flow velocities induced by local injection with papaverine/phentolamine showed no difference between the groups before and 6 months after orchidectomy. Loss of libido and erectile dysfunction were reported more frequently by BEP-treated patients. However, 1 year after treatment, most reported a satisfying sex life and VES resulted in a rigid erection in nearly all patients. The reported erectile dysfunction could not be explained by changes in plasma testosterone levels or diminished blood flow velocities. CONCLUSIONS After being diagnosed with testicular cancer, sexual morbidity is considerable, but within 1 year some improvement may be expected. BEP induces transient testicular dysfunction but this recovers. Although BEP is related to symptoms of angiopathy, cavernosal blood flow seems to be unaffected. These findings and the normal VES-evoked penile rigidity suggest that sexual dysfunction is more psychological than organically induced by BEP.

Men were interviewed by telephone; 514 men with cancer and 720 controls participated. OUTCOME MEASURE Occurrence of testicular cancer. RESULTS A reduced risk of testicular cancer was associated with paternity (relative risk 0.63; 95% confidence interval 0.47 to 0.85). In men who before the diagnosis of testicular cancer had a lower number of children than expected on the basis of their age, the relative risk was 1.98 (1.43 to 2.75). There was no corresponding protective effect associated with a higher number of children than expected. The associations were similar for seminoma and non-seminoma and were not influenced by adjustment for potential confounding factors. CONCLUSION These data are consistent with the hypothesis that male subfertility and testicular cancer share important aetiological factors.

Abstract
PURPOSE We evaluate the use of pretreatment follicle-stimulating hormone (FSH) in patients with germ cell tumors as a prognostic serum marker of spermatogenesis after standard treatment. Additionally, Leydig cell function was investigated by estimation of luteinizing hormone (LH) and testosterone (T), and calculation of the T/LH ratio. MATERIALS AND METHODS Serum FSH, LH and T were determined radioimmunologically associated with semen analyses in 20 patients with seminoma (pathological stages IA to IIB) after unilateral orchiectomy before and up to 24 months after infradiaphragmatic radiotherapy. Additionally, hormone analyses were performed in 18 patients with nonseminomatous germ cell tumor (pathological stages IIA to C) before and up to 36 months after standard cisplatin based chemotherapy. RESULTS Seminoma patients undergoing radiotherapy were divided into 2 groups consisting of 12 patients with normal pretreatment serum FSH and 8 with elevated FSH reflecting spermatogenesis deficits even before treatment. Six months after irradiation a significant increase in FSH (p <0.01) associated with a decrease in sperm density was observed in both groups and 24 months after radiotherapy patients with initially normal FSH had significantly lower serum FSH (p <0.01) associated with higher sperm density than those with initially elevated FSH (p <0.01), indicating less impairment of Sertoli cell function. Comparable results were observed in chemotherapy treated germ cell tumor patients with initially normal (11) and elevated serum FSH (7), respectively, and 36 months after chemotherapy patients with initially normal FSH had significantly lower FSH concentrations than those with initially elevated FSH (p <0.01). Compensated impairment of Leydig cell function reflected by a subnormal T/LH ratio was evident before chemotherapy in 16.7% of patients increasing up to 41.2% 36 months after therapy. In contrast, 24 months after radiotherapy only 25% of seminoma patients showed a subnormal ratio reflecting less damage to the Leydig cells caused by irradiation. CONCLUSIONS Pretreatment FSH is a prognostic serum marker of spermatogenesis status of germ cell tumor patients receiving standard radiotherapy or chemotherapy. In contrast to seminoma patients after radiotherapy, impairment of Leydig cell function was evident in germ cell tumor patients after cisplatin based chemotherapy.

Abstract
Radiation and chemotherapeutic drugs produce prolonged depression of sperm counts in rodents and humans. Previously, three approaches have been developed in experimental animals that have had some success in preventing or reversing this toxicity. These approaches included pretreatment with hormones that suppress spermatogenesis, stimulation of stem cell number, and supplementation with testosterone. A different rationale for the ability of particular hormonal treatments to reverse prolonged azoospermia is presented in this review. In many cases prolonged azoospermia occurs even though the stem spermatogonia survive the toxic insult, but the differentiation of these spermatogonia to produce sperm fails. In the rat, the block appears to be at the differentiation of the A spermatogonia. Hormone treatments with testosterone or with GnRH agonists, which suppress intratesticular testosterone levels, relieve this block and result in the production of differentiating cells. When the hormone treatment is stopped the production of differentiating cells continues, mature sperm are produced, and fertility is restored. If a similar mechanism can be demonstrated to hold in humans, the fertility of men who have been rendered infertile by treatments for testicular and other cancers could be improved.

Abstract
This paper reviews current knowledge about the effect of testicular germ cell cancer (TGCC) on gonadal function and of cancer treatment on spermatogenesis and Leydig cell function. It is well documented that testicular cancer is associated with impaired spermatogenic function and some patients already have impairment of Leydig cell function before orchidectomy. The degree of spermatogenic dysfunction is higher than what can be explained by local tumour effect and by a general cancer effect, since patients with other malignant diseases have normal, or only slightly decreased, semen quality. Furthermore, sperm counts after orchidectomy are further reduced to less than half of the values in healthy men, even in patients cured from the cancer disease after orchidectomy alone. These observations are supported by histological investigations which have shown a high prevalence of abnormalities of spermatogenesis in the contralateral testis in patients with unilateral TGCC. The association between testicular cancer and poor gonadal function is very interesting both from a biological and from a therapeutic point of view. Firstly, the increase in incidence of testicular cancer has been suggested to be associated with a general decline in male reproductive health and it seems likely that the development of TGCC shares common aetiologic factors with development of other types of testicular dysfunction. This suggestion is supported by the observation that men with various types of gonadal dysfunction such as testicular dysgenesis, androgen insensitivity syndrome, and cryptorchidism have increased risk of testicular cancer. Secondly, the general cure rate in patients with testicular cancer exceeds 90% and the quality of life, including fertility aspects, is therefore important in the management of these patients. Spermatogenesis is already so severely impaired before treatment that fertility is lower than in healthy men. Moreover, radiotherapy and chemotherapy both induce dose-dependent impairment of spermatogenesis and recovery of spermatogenesis after treatment may be long lasting even more than five years in some patients. Sufficient androgen production is seen in the majority of the patients, but some patients suffer from testosterone deficiency. The effect of chemotherapy on Leydig cell function also seems to be dose-dependent. In conclusion there is no doubt that testicular cancer is associated with poor gonadal function even before treatment. Furthermore, the treatment of testicular cancer may have a serious impact on the gonadal function in these patients, most of whom are in the reproductive age. Moreover, the epidemiological and clinical data indicate a common aetiology between testicular germ cell cancer and other abnormalities in male reproductive health (such as infertility and cryptorchidism). These observations are in agreement with the suggestions of hormonal involvement in the aetiology of testicular cancer. Generally, men with TGCC need counselling about their reproductive function with respect to semen cryopreservation, chance of recovery of spermatogenesis, fertility, and the possible need for androgen replacement.

Abstract
PURPOSE The cure rate of patients with germ cell cancer of the testis has considerably improved since the introduction of cisplatin based chemotherapy. Because these patients are in their reproductive years and because some of them will be infertile after treatment, the effects of cytotoxic treatment on gonadal function are investigated by hormonal evaluations. MATERIALS AND METHODS In a transversal trial, luteinizing hormone, follicle-stimulating hormone and testosterone were determined radioimmunologically in serum samples of 232 patients with germ cell tumors after unilateral orchiectomy (patient age 18 to 64 years) up to 153 months after chemotherapy. Additionally, 51 of these patients were investigated in a longitudinal trial before and up to 5 years after chemotherapy. All patients received at least 2 courses of different cisplatin based chemotherapy regimens: cisplatin/vinblastine/bleomycin, cisplatin/vinblastine/bleomycin/ifosfamide, cisplatin/etoposide/bleomycin, cisplatin/vinblastine/bleomycin/ifosfamide/etoposide. Additionally, 11 patients with germ cell tumors (age 22 to 38 years, stage I) were investigated within the first year after orchiectomy and retroperitoneal lymphadenectomy but without chemotherapy. RESULTS In the transversal trial, 24 of 73 patients investigated during the first year after chemotherapy showed elevated luteinizing hormone concentrations, 5 had subnormal serum testosterone and 65 had elevated serum follicle-stimulating hormone, reflecting spermatogenesis deficits. In 28 patients studied longer than 8 years after chemotherapy (median followup 8.5 years, range 8.0 to 12.6), luteinizing hormone increased after chemotherapy and 60 months after treatment, and follicle-stimulating hormone was elevated in 1 patient, follicle-stimulating hormone was increased in 18 and testosterone was subnormal in 1. Patients without chemotherapy treatment showed gonadotropin and testosterone within normal range and 3 patients had elevated serum follicle-stimulating hormone. In the longitudinal study, mean serum luteinizing hormone plus or minus standard deviation (3.45 +/- 0.05 IU/l.), follicle-stimulating hormone (7.79 +/- 0.13 IU/l.) and testosterone (18.6 +/- 0.17 nmol./l.) were within the normal range before chemotherapy; serum follicle-stimulating hormone was still significantly elevated (16.9 +/- 0.71 IU/l., 19 cases, p < 0.001). Mean luteinizing hormone and testosterone levels were within the normal range, but 60 months after therapy the testosterone-to-luteinizing hormone ratio was still lower than before treatment (p < 0.05). CONCLUSIONS In patients with germ cell tumors, a compensated insufficiency of the function of the Leydig cells was still observed up to 60 months after chemotherapy. Of these patients 68% showed elevated follicle-stimulating hormone levels, which reflected a functional insufficiency of the Sertoli cells with impaired spermatogenesis. This study shows that impairment of germinative functions is more severe and protracted than the impairment of the endocrine functions.

Abstract
In adult oncological patients semen cryopreservation offers the possibility of preserving fertility prior to aggressive therapy that may lead to infertility. The cryopreserved semen can later be used to induce pregnancies in the partner by techniques of assisted fertilization. In adolescent boys the question of fertility is often beyond consideration when the young patient's life is threatened acutely. However, improved survival rates increasingly prompt the question of quality of life after therapy, including fertility. Semen quality is known to be impaired in patients with malignancies and may be further impaired by the process of cryopreservation. Since normal values for semen in adolescents are not known and spermatogenesis may be impaired by the malignant disease, it was unclear whether semen samples from adolescents with malignancies warrant cryopreservation at all. In order to demonstrate the feasibility of semen cryopreservation in adolescent males, we compared the results from 12 pubertal boys aged 14-17 years with those from 17 young adults aged 18-20 years who had similar malignancies and, additionally, to 210 adults with malignancies (> 20 years). Luteinizing hormone serum values were significantly lower in adolescents than in adult patients. Follicle stimulating hormone showed a significant increase with age. Testosterone serum levels and testicular volumes showed similar distribution patterns in adolescent and adult men. Sperm concentrations, sperm motility, and normal sperm morphology in the adolescent patients did not show significant differences compared with adults. Thus cryopreservation of semen should be considered as an option to young male patients whose cancer therapy will include potentially gonadotoxic treatment.

Abstract
BACKGROUND The enormous differences in semen quality following cisplatin-based combination chemotherapy reported in previous studies may be caused by differences in the cisplatin dosages. PATIENTS AND METHODS We examined thirty-three patients treated with conventional-dose PEB (cisplatin 20 mg/m2 x 5, q3w, etoposide 100 mg/m2 x 5 q3w and bleomycin 15 mg/m2 q1w) and 21 patients treated with high-dose PEB (cisplatin 40 mg/m2 x 5 q3w, etoposide 200 mg/m2 x 5 q3w and bleomycin 15 mg/m2 q1w). RESULTS The sperm density was significantly higher (median 5.83 mill/ml) in the conventionally-treated group than in the group of high-dose-treated patients (median 0.005 mill/ml) (p = 0.008). Azoospermia was present in 19% of the conventionally- and in 47% of the high-dose-treated patients. All patients treated with a cumulative cisplatin dose above 600 mg/m2 had severe oligospermia or azoospermia. Serum values of basal follicle-stimulating hormone (FSH) (median 27.2 iu/l vs. 15.2 iu/l) and stimulated FSH (median 57.7 iu/l vs. 28.4 iu/l) were significantly higher in the high-dose group than in the conventionally-treated group. No differences could be detected in basal or stimulated testosterone or in luteinizing hormone in serum. CONCLUSION In patients treated with PEB for testicular cancer, we found strong evidence that the impairment of spermatogenesis is dose-dependent.

Abstract
In the present study, the influence of carboplatin [diammine(cyclobutane-1,1-dicarboxylato)platinum(II)], the main and most active representative of second-generation antitumour platinum complexes, on the morphology of the testes of male CF1 mice was investigated histologically by examining semithick sections. Carboplatin was administered in doses of 30, 60, or 120 mg/kg and applied as a single intraperitoneal injection. For comparison purposes, the parent compound cisplatin [cis-diamminedichloroplatinum(II)] was administered at equitoxic doses (3, 6 or 12 mg/kg). At various intervals between days 1 and 28 after treatment, the testes were removed and embedded in Epon. Both compounds effected severe structural alterations of Sertoli cells, disrupted the blood/testis barrier, and impaired the processes both of spermatogenesis and spermiohistogenesis. The structural damage in the testes following treatment with carboplatin was at least as pronounced as that occurring under the influence of equitoxic doses of cisplatin. Within a few days, the intercellular spaces around Sertoli cells widened, the tight contacts with neighbouring cells were disrupted, the cytoplasm of Sertoli cells disintegrated and their nuclei shrank. Numerous necroses, abnormal mitotic figures of spermatogenic cells and malformed spermatozoa appeared. Severe damage was evident on days 10-21 after treatment with carboplatin, the strength of the symptoms being clearly dependent on the dose applied. The first indications of ongoing recovery processes were detected on day 21 in the case of the low dose (30 mg/kg) or on day 28 following treatment with 60 mg/kg or 120 mg/kg. These results confirm that carboplatin is at least as toxic to the testes as cisplatin and that its substitution for cisplatin in clinical therapy does not diminish the problem of drug-induced infertility following platinum-based chemotherapy.

Abstract
Paternity before and after treatment was investigated in 177 patients with unilateral germ cell tumours of the testis. Before the cancer was diagnosed, 51% had fathered at least 1 child, 9% had a history of infertility and 40% had not wanted to have children. It was estimated that 72% of the patients would have fathered at least 1 child at the age of 40 years. After treatment 41 patients had wished to have children. Infertility was still a problem 5 years after the end of treatment in 53% of these men. No significant differences was observed between patients treated with orchiectomy alone and patients treated with cisplatin-based chemotherapy or subdiaphragmatic irradiation. In 8 patients, infertility was present in spite of an evident recovery of spermatogenesis. Congenital malformations were recorded in 3.8% of the live-born children conceived before the orchiectomy. This incidence did not exceed the Danish national rate, the relative risk being 2.5 (95% confidence limits, 0.9-5.5). No malformations were observed in the 22 children conceived after ending treatment.

Abstract
Over a 7-year period, semen analysis was performed in 92 male patients with Hodgkin's disease prior to therapy. In 67% of patients semen revealed a decreased chance for fertility (i.e. oligozoospermia, asthenozoospermia and/or teratozoospermia). The mean basal levels of follicle-stimulating hormone (FSH), luteinising hormone, testosterone and prolactin were in the normal range. In 77 patients in complete remission after alternating MOPP/ABVD (mechlorethamine, vincristine, procarbazine, prednisone; doxorubicin, bleomycin, vinblastine, dacarbazine), testicular function was assessed. 87% of patients were azoospermic, 9% had semen abnormalities and only 4% were normospermic. Recovery of spermatogenesis was documented in only 17 of 42 (40%) reassessed patients after a median time of 27 months and was generally not affected by pretreatment sperm quality. After chemotherapy, the mean value of FSH [20.45 (S.E. 1.7) mUI/ml] was significantly superior compared with that of the mean pretreatment values. No difference was documented in the mean testosterone and prolactin values tested before and after treatment. Our findings indicate that, of patients with Hodgkin's disease, about half are affected by hypogonadism before starting chemotherapy. By utilising alternating MOPP/ABVD, persistent testicular dysfunction was documented in half of the patients.

Abstract
Gonadal function was evaluated before irradiation and by serial analyses after treatment in 27 patients with seminomas and 24 patients with nonseminomatous germ cell tumors of the testis. During subdiaphragmatic irradiation, a median testicular dose of 1.7 Gy (range, 1.2 to 4.8 Gy) reached the remaining testis. Twenty nonseminoma patients were treated with adjuvant chemotherapy using vincristine and bleomycin (OB) or cisplatin/dactinomycin, vinblastine, and bleomycin (P/DVB). After orchiectomy, 94% had spermatozoa in semen, 49% had a total sperm count exceeding the reference value (80 x 10(6], and in 67% serum follicle-stimulating hormone levels were normal. The corresponding estimated values 5 and 9 years after treatment were 61%, 13%, 14%, and 84%, 35%, 32%, respectively. A Cox regression analysis of recovery, with azoospermia used as an endpoint, showed that (1) recovery depended on the radiation dose, (2) adjuvant chemotherapy prolonged the recovery period, (3) recovery was decreased in patients with low pretreatment total sperm counts and in patients older than 25 years. A prognostic index was derived from the regression model and radiation dose-response curves were calculated (+/- chemotherapy). We conclude that a profound, dose-dependent impairment of spermatogenesis is caused by radiation scatter reaching the testis during subdiaphragmal irradiation. An effective gonadal shield should reduce the gonadal dose to a level low enough to preserve spermatogenesis in most patients.

Abstract
In a study designed to assess the potential teratogenic effect of paternal chemotherapy, information was obtained on 131 children fathered by 107 men treated for metastatic testicular cancer. Of this group, first born children fathered by 96 chemotherapy patients were compared with 96 children fathered by matched controls. There was no excess of malformations (relative risk 1.0, 95% confidence intervals 0.41 and 2.40). In addition, the rates for specific malformations in the total cohort of 131 children were compared with the general population. There were no significant differences from national rates although the rate for congenital heart disease was higher than expected.
