Postchemotherapy ejaculatory azoospermia: fatherhood with sperm from testis tissue with intracytoplasmic sperm injection

Reproductive Chances of Men with Azoospermia Due to Spermatogenic Dysfunction

Non-obstructive azoospermia (NOA), or lack of sperm in the ejaculate due to spermatogenic dysfunction, is the most severe form of infertility. Men with this form of infertility should be evaluated prior to treatment, as there are various underlying etiologies for NOA. While a significant proportion of NOA men have idiopathic spermatogenic dysfunction, known etiologies including genetic disorders, hormonal anomalies, structural abnormalities, chemotherapy or radiation treatment, infection and inflammation may substantively affect the prognosis for successful treatment. Despite the underlying etiology for NOA, most of these infertile men are candidates for surgical sperm retrieval and subsequent use in intracytoplasmic sperm injection (ICSI). In this review, we describe common etiologies of NOA and clinical outcomes following surgical sperm retrieval and ICSI.

Testicular sperm extraction and intracytoplasmic sperm injection outcome in cancer survivors with no available cryopreserved sperm

OBJECTIVE

To assess rates of successful testicular sperm retrieval and intracytoplasmic sperm injection (ICSI) outcome in cancer survivors affected by non-obstructive azoospermia (NOA) or retrograde ejaculation (RE)/failure of emission (FOE).

METHODS

A retrospective analysis of cancer survivors who did not cryopreserve sperm prior to treatment undergoing testicular sperm extraction (TESE). Non-cancer NOA patients and neurologic RE/FOE were the control group.

RESULTS

A total of 97 cancer survivors were offered TESE and 88 (91%) accepted. Sperm was retrieved and cryopreserved in 34/67 patients with NOA (50.7%) and in 21/21 patients affected by RE/FOE (100%). Sperm retrieval rates were similar in the control group (44.9% in NOA and 100% in RE/FOE). The ICSI cumulative pregnancy rate (60%) and live birth rate (40%) per couple in 30 NOA men did not differ from controls (50.0 and 46.5%, respectively; p = 0.399/0.670). The cumulative pregnancy rate (66.7%) and live birth rate (55.6%) in 18 RE/FOE men did not differ from the control group (38.9 and 33.3%, respectively; p = 0.181/0.315). The cancer type and the resulting infertility disorder (NOA or RE/FOE) were not associated with ICSI outcomes. Female partner age was inversely related to the cumulative live birth rate, being fourfold lower (11.5%) in women ≥ 40 years and 48.8% in younger women (p = 0.0037).

CONCLUSIONS

The rate of successful TESE and the ICSI outcome in cancer survivors with NOA and RE/FOE is the same as non-cancer azoospermic patients. Female partner age (older than 40 years) was associated with a significant reduction in live birth rates after TESE-ICSI procedures.

Fertility preservation options in transgender people: A review

Gender affirming procedures adversely affect the reproductive potential of transgender people. Thus, fertility preservation options should be discussed with all transpeople before medical and surgical transition. In transwomen, semen cryopreservation is typically straightforward and widely available at fertility centers. The optimal number of vials frozen depends on their reproductive goals and treatment options, therefore a consultation with a fertility specialist is optimal. Experimental techniques including spermatogonium stem cells (SSC) and testicular tissue preservation are technologies currently under development in prepubertal individuals but are not yet clinically available. In transmen, embryo and/or oocyte cryopreservation is currently the best option for fertility preservation. Embryo cryopreservation requires fertilization of the transman's oocytes with a donor or partner's sperm prior to cryopreservation, but this limits his future options for fertilizing the eggs with another partner or donor. Oocyte cryopreservation offers transmen the opportunity to preserve their fertility without committing to a male partner or sperm donor at the time of cryopreservation. Both techniques however require at least a two-week treatment course, egg retrieval under sedation and considerable cost. Ovarian tissue cryopreservation is a promising experimental method that may be performed at the same time as gender affirming surgery but is offered in only a limited amount of centers worldwide. In select places, this method may be considered for prepubertal children, adolescents, and adults when ovarian stimulation is not possible. Novel methods such as in-vitro activation of primordial follicles, in vitro maturation of immature oocytes and artificial gametes are under development and may hold promise for the future.

Protective effects of curcumin against doxorubicin-induced toxicity and resistance: A review

Doxorubicin (DOX)-induced toxicity and resistance are major obstacles in chemotherapeutic approaches. Despite effective in the treatment of numerous malignancies, some clinicians have voiced concern that DOX has the potential to cause debilitating consequences in organ tissues, especially the heart. The mechanisms of toxicity and resistance are respectively related to induction of reactive oxygen species (ROS) and up-regulation of ATP-binding cassette (ABC) transporter. Curcumin (CUR) with several biological and pharmacological properties is expected to restore DOX-mediated impairments to tissues. This review is intended to address the current knowledge on DOX adverse effects and CUR protective actions in the heart, kidneys, liver, brain, and reproductive organs. Coadministration of CUR and DOX is capable of ameliorating DOX toxicity pertained to antioxidant, apoptosis, autophagy, and mitochondrial permeability.

IVF outcome in azoospermic cancer survivors

OBJECTIVE

To assess clinical outcome among infertile couples treated by in vitro fertilization (IVF) and intra cytoplasmic sperm injection (ICSI) using testicular sperm from azoospermic cancer survivors.

STUDY DESIGN

This clinical retrospective study included infertile couples treated in a single tertiary referral center between 1996 and 2013. All male partners were cancer survivors who were diagnosed with azoospermia due to previous gonadotoxic treatments and referred to testicular sperm extraction (TESE). Retrieved sperm was used for IVF-ICSI among patients' spouses. Sperm retrieval rate and IVF-ICSI outcome were evaluated.

RESULTS

Sperm was successfully retrieved in 12 out of 36 patients (33.3%) on initial TESE, with an overall sperm retrieval rate of 38.6% (17 of 44). Female patients were 29.8±5.1 years old. The average number of retrieved oocytes was 14.0±4.0 per cycle, with clinical pregnancy and live birth rates per successful TESE of 64% (11 of 17) and 58.8% (10 of 17), respectively. Age, serum FSH, testicular volume and time from chemotherapy to TESE were not significantly different between patients with successful TESE to those without. Patients suffering from seminomas had significantly higher sperm retrieval rate, as compared to patients who had Hodgkin's lymphoma (P=0.024).

CONCLUSIONS

Post-chemotherapy azoospermia can be successfully treated with TESE and ICSI, and should be offered to azoospermic cancer survivors who did not cryopreserve sperm prior to their gonadotoxic treatments.

The positive effect of a dedicated adolescent and young adult fertility program on the rates of documentation of therapy-associated infertility risk and fertility preservation options

PURPOSE

Minimal data exist regarding documentation of therapy-associated infertility risk (IR) and fertility preservation (FP) options during the initial oncology consultation prior to systemic therapy. This study investigated factors affecting IR/FP documentation and assessed the effect of implementation of an Adolescent and Young Adult (AYA) program on documentation rates.

METHODS

A retrospective review of charts of patients receiving gonadotoxic therapy was undertaken for documentation of IR/FP pre- and post-implementation of an AYA program. Change in documentation rates was assessed using univariate and multiple logistic regression.

RESULTS

A total of 173 charts were reviewed. On univariate analysis, IR/FP documentation was less likely if patients had metastatic disease (P < 0.01, P < 0.01), by tumor type (P < 0.01, P < 0.01), received less intensive chemotherapy (P = 0.03, P = 0.06), were older (P = 0.14, P < 0.01), had more children (P < 0.01, P < 0.01), or lacked AYA program involvement (P < 0.01, P < 0.01). FP discussion was more common in males (P = 0.02). On multivariable analysis, more children (P = 0.01, P = 0.03), older age (P < 0.01, P < 0.01), tumor type (P < 0.01, P = 0.01), stage (P = 0.02, NS), relationship (P = 0.03, NS), and lack of AYA involvement (P < 0.01, P < 0.01) were associated with lower rates of IR/FP documentation. Following AYA program implementation, IR/FP rates increased from 56% (CI 46-65%) to 85% (CI 74-92%, P < 0.01) and 54% (CI 45-64%) to 86% (CI 75-93%, P < 0.01), respectively. The effect of AYA program implementation on IR/FP documentation was most noticeable in leukemia, lymphoma, and breast groups (P < 0.01).

CONCLUSIONS

Implementing an AYA consultation service at an adult cancer institution had a positive effect on the rates of IR/FP documentation. Specific programming can improve service delivery to AYA cancer patients, and fertility counseling should be integrated for patients undergoing gonadotoxic therapy.

Testicular function among testicular cancer survivors treated with cisplatin-based chemotherapy

Purpose

The aim of our study was to identify the clinical predictors of spermatogenesis recovery in testicular cancer (TC) patients after chemotherapy and to determine the recuperation period for spermatogenesis.

Methods

Patients treated for TC from January 1982 to November 2001 at Chiba University Hospital were retrospectively assessed. Thirty-five patients who met the following criteria were examined-(i) underwent both high orchiectomy and cisplatin-based chemotherapy; (ii) had semen analyses and hormonal measurements; and (iii) were alive with no evidence of disease. Clinical variables associated with normalization of spermatogenesis after chemotherapy were examined. Time to recover normospermia was also evaluated using Kaplan-Meier analysis.

Results

The observation period was 13.3 ± 5.6 years. Reappearance of sperm was confirmed in 85.7 % of patients, and 54.3 % of patients recovered normospermia. Age at diagnosis <25 years (p = 0.0057), number of chemotherapy cycles <4 cycles (p = 0.0042), and follicle-stimulating hormone at the end of chemotherapy <18 mIU/ml (p = 0.0220) were independent factors related to post-chemotherapy normalization of semen findings. The median (95 % CI) time to recover normospermia was 40 (range 22-96) months.

Conclusions

These findings help to predict whether spermatogenesis will recover and its timing. They may also help clinicians identify and manage TC patients at a higher risk of prolonged azoospermia after chemotherapy.

Experimental methods to preserve male fertility and treat male factor infertility

Infertility is a prevalent condition that has insidious impacts on the infertile individuals, their families, and society, which extend far beyond the inability to have a biological child. Lifestyle changes, fertility treatments, and assisted reproductive technology (ART) are available to help many infertile couples achieve their reproductive goals. All of these technologies require that the infertile individual is able to produce at least a small number of functional gametes (eggs or sperm). It is not possible for a person who does not produce gametes to have a biological child. This review focuses on the infertile man and describes several stem cell-based methods and gene therapy approaches that are in the research pipeline and may lead to new fertility treatment options for men with azoospermia.

Azoospermia due to spermatogenic failure

This article summarizes the current literature regarding azoospermia caused by spermatogenic failure. The causes and genetic contributions to spermatogenic failure are reviewed. Medical therapies including use of hormonal manipulation, whether guided by a specific abnormality or empiric, to induce spermatogenesis are discussed. The role of surgical therapy, including a discussion of varicocelectomy in men with spermatogenic failure, as well as an in-depth review of surgical sperm retrieval with testicular sperm extraction and microdissection testicular sperm extraction, is provided. Finally, future directions of treatment for men with spermatogenic failure are discussed, namely, stem cell and gene therapy.

Male reproductive health after childhood, adolescent, and young adult cancers: a report from the Children's Oncology Group

The majority of children, adolescents, and young adults diagnosed with cancer will become long-term survivors. Although cancer therapy is associated with many adverse effects, one of the primary concerns of young male cancer survivors is reproductive health. Future fertility is often the focus of concern; however, it must be recognized that all aspects of male health, including pubertal development, testosterone production, and sexual function, can be impaired by cancer therapy. Although pretreatment strategies to preserve reproductive health have been beneficial to some male patients, many survivors remain at risk for long-term reproductive complications. Understanding risk factors and monitoring the reproductive health of young male survivors are important aspects of follow-up care. The Children's Oncology Group Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancer (COG-LTFU Guidelines) were created by the COG to provide recommendations for follow-up care of survivors at risk for long-term complications. The male health task force of the COG-LTFU Guidelines, composed of pediatric oncologists, endocrinologists, nurse practitioners, a urologist, and a radiation oncologist, is responsible for updating the COG-LTFU Guidelines every 2 years based on literature review and expert consensus. This review summarizes current task force recommendations for the assessment and management of male reproductive complications after treatment for childhood, adolescent, and young adult cancers. Issues related to male health that are being investigated, but currently not included in the COG-LTFU Guidelines, are also discussed. Ongoing investigation will inform future COG-LTFU Guideline recommendations for follow-up care to improve health and quality of life for male survivors.

Sperm banking and the cancer patient

The current concepts, recommendations, and principles of sperm banking as it pertains to the comprehensive care of young men of reproductive age with cancer are reviewed. Obstacles to sperm banking are addressed as well as future directions for fertility-preserving technologies. All cancer therapies-chemotherapy, radiation, and surgery-are potential threats to a man's reproductive potential. In addition, cancer itself can impair spermatogenesis. Thus, sperm cryopreservation prior to initiating life-saving cancer treatment offers men and their families the best chance to father biologically related children and should be offered to all men with cancer before treatment. Better patient and provider education, as well as deliberate, coordinated strategies at comprehensive cancer care centers are necessary to make fertility preservation for male cancer patients a priority during pretreatment planning.

The value of testicular 'mapping' in men with non-obstructive azoospermia

As the field of assisted reproduction has advanced, many previously untreatable men are now biological fathers. Although finding sperm in men with obstructive azoospermia is not difficult, locating and retrieving spermatozoa in men with non-obstructive azoospermia remains a clinical challenge, largely because sperm production in these men can be patchy or focal in nature. In response to this challenge, strategies such as fine-needle aspiration (FNA) mapping have been developed to find spermatozoa. This review discusses the history, evolution and current clinical utility and findings with FNA mapping for male infertility). Review of the current literature in the English language on FNA (diagnostic or therapeutic) with a keyword focuses on sperm detection, retrieval, safety and complications. FNA was described in human medicine over 100 years ago. Testis FNA was described 45 years ago and FNA 'mapping' of spermatozoa was described in 1997. This comparative review of the literature on sperm detection and complication rates with FNA and open testis biopsy or microdissection procedures suggests that FNA is highly informative, minimally invasive and is associated with fewer complications than other commonly used approaches to sperm detection in non-obstructive azoospermic patients. FNA mapping has gained considerable traction as an informative, 'testis sparing' technique for sperm detection in non-obstructive azoospermia. With knowledge of sperm presence and location prior to sperm retrieval, FNA maps can help clinicians tailor sperm retrieval to optimize time, effort and extent of procedures needed to procure spermatozoa in these difficult cases.

Proanthocyanidins produce significant attenuation of doxorubicin-induced mutagenicity via suppression of oxidative stress

This study has been initiated to determine whether proanthocyanidins can protect against doxorubicin-induced mutagenicity in mice and to elucidate the potential mechanism of this protection. Pretreatment of mice with proanthocyanidins (100 mg/kg/day, orally) for 7 days and simultaneously with doxorubicin (12 mg/kg, i.p.) for another day, significantly reduced the frequency of bone marrow DNA strand breaks and micronucleated polychromatic erythrocytes compared to doxorubicin-treated mice alone. Furthermore, proanthocyanidins caused a reduction in bone marrow suppression induced by doxorubicin treatment. In male germline, orally administration of proanthocyanidins (100 mg/kg/day, orally) for 7 consecutive days before and 7 consecutive days after treatment with doxorubicin (12 mg/kg, i.p.), significantly elevated the levels of sperm count and motility reduced by doxorubicin treatment. Furthermore, proanthocyanidins significantly decreased the elevated levels of spermatogonial and spermatocyte chromosomal aberrations and sperm head abnormality induced by doxorubicin. Prior administration of proanthocyanidins ahead of doxorubicin reduced the doxorubicin induced testicular lipid peroxidation and prevented the reduction in testicular non-protein sulfhydryl significantly. Conclusively, this study provides for the first time that proanthocyanidins have a protective role in the abatement of doxorubicin-induced mutagenesis and cell proliferation changes in germinal cells of mice that reside, at least in part, in their radical scavenger activity. Therefore, proanthocyanidins can be a promising chemopreventive agent to avert secondary malignancy and abnormal reproductive outcomes risks in cancer patients receiving doxorubicin-involved treatment.

The genetic and phenotypic basis of infertility in men with pediatric urologic disorders

Male factor is a major component of infertility for many couples. The presence of congenital genitourinary anomalies in male partners can cause male infertility. We reviewed the state-of-the-art treatment and outcomes for male infertility caused by pediatric urologic disorders. Disorders were classified by whether they led to infertility through pre-testis, testicular, or post-testis effects. Despite the complexity of pediatric urologic disorders that can affect fertility, natural paternity and paternity through assisted reproductive technology are common. Given the significant recent advances in infertility treatments, paternity with many currently untreatable pediatric disorders is likely in the future.

Amifostine reduces the seminiferous epithelium damage in doxorubicin-treated prepubertal rats without improving the fertility status

BACKGROUND

Amifostine is an efficient cytoprotector against toxicity caused by some chemotherapeutic drugs. Doxorubicin, a potent anticancer anthracycline, is known to produce spermatogenic damage even in low doses. Although some studies have suggested that amifostine does not confer protection to doxorubicin-induced testicular damage, schedules and age of treatment have different approach depending on the protocol. Thus, we proposed to investigate the potential cytoprotective action of amifostine against the damage provoked by doxorubicin to prepubertal rat testes (30-day-old) by assessing some macro and microscopic morphometric parameters 15, 30 and 60 days after the treatment; for fertility evaluation, quantitative analyses of sperm parameters and reproductive competence in the adult phase were also carried out.

METHODS

Thirty-day-old male rats were distributed into four groups: Doxorubicin (5 mg/kg), Amifostine (400 mg/kg), Amifostine/Doxorubicin (amifostine 15 minutes before doxorubicin) and Sham Control (0.9% saline solution). "Standard One Way Anova" parametric and "Anova on Ranks" non-parametric tests were applied according to the behavior of the obtained data; significant differences were considered when p < 0.05.

RESULTS

The rats killed 30 and 60 days after doxorubicin treatment showed diminution of seminiferous epithelium height and reduction on the frequency of tubular sections containing at least one type of differentiated spermatogonia; reduction of sperm concentration and motility and an increase of sperm anomalous forms where observed in doxorubicin-treated animals. All these parameters were improved in the Amifostine/Doxorubicin group only when compared to Doxorubicin group. Such reduction, however, still remained below the values obtained from the Sham Control group. Nevertheless, the reproductive competence of doxorubicin-treated rats was not improved by amifostine pre-administration.

CONCLUSIONS

These results suggest that amifostine promotes a significant reduction of the doxorubicin long-term side effects on the seminiferous epithelium of prepubertal rats, which is reflected in the epidydimal fluid parameters in the adult phase. However, fertility status results suggest that such protection may not be effective against sperm DNA content damage. Further investigation of sperm DNA integrity must be carried out using amifostine and doxorubicin-treated experimental models.

Which is the best sperm retrieval technique for non-obstructive azoospermia? A systematic review

Our objective was to establish which is the best sperm retrieval technique in non-obstructive azoospermia based on the available evidence. To date, no randomized controlled trial has compared the efficiency of these strategies and thus current recommendations are based on cumulative evidence provided by descriptive, observational and controlled studies. Three outcome measures were assessed for the sperm retrieval techniques: sperm retrieval rate (SRR), complications and live birth rate. Twenty-four descriptive studies reporting on the results of testicular sperm extraction (TESE) were encountered. Seven controlled studies that compared microdissection (MD) TESE with conventional TESE and seven controlled studies comparing fine needle testicular aspiration (FNA) with TESE were identified. The mean SRR for TESE was 49.5% (95% CI 49.0-49.9). TESE with multiple biopsies results in a higher SRR than FNA especially in cases of Sertoli-cell-only (SCO) syndrome and maturation arrest. Current evidence suggests that MD performs better than conventional TESE only in cases of SCO where tubules containing active focus of spermatogenesis can be identified. MD appears to be the safest technique regarding post-operative complications followed by FNA. Only three studies could be identified concerning the influence of the sperm retrieval technique on clinical pregnancy and live birth rate, hence no definitive conclusions can be made. However, so far there appears to be no impact of the technique itself on success rates.

The effects of cancer and cancer treatments on male reproductive function

In male cancer patients, surgery, radiotherapy and chemotherapy can be followed by transient or permanent infertility by affecting ejaculatory or erectile function, or by impairing spermatogenesis. Cancer specialists should, therefore, discuss the impact of different therapies on fertility with their patients prior to treatment, and consider fertility-preserving measures before and during treatment, such as nerve-sparing operative techniques, adequate testicular shielding during radiotherapy and the avoidance of unnecessary gonadotoxic chemotherapy. Pretreatment sperm-cell cryopreservation should be offered, even in cases where the individual's risk of post-treatment infertility might seem minimal or if it might require testicular sperm-cell extraction. Samples that are severely oligospermic should also be cryopreserved. Post-treatment ejaculatory or erectile dysfunction can be reversed pharmacologically, but the success rate varies with the extent of neurologic sequelae of the treatments used. At present there is no established method to stimulate post-treatment impaired spermatogenesis, although currently available assisted reproductive techniques overcome some of the existing problems of infertility in cancer survivors, and ongoing research will hopefully increase these possibilities. A multidisciplinary approach that depends on close cooperation between relevant medical specialists is central to achieving such advances.

Definition and current evaluation of subfertile men

Male infertility affects 10% of reproductive aged couples worldwide and is treatable in many cases. In addition to other well-described etiologies, genetic causes of male infertility are now more commonly diagnosed. Using principles of evidence-based medicine, this review outlines diagnostic and treatments options to inform clinical management. In order of importance, randomized controlled clinical trials, basic scientific studies, meta-analyses, case-controlled cohort studies, best-practice policy recommendations and reviews from peer-reviewed literature were incorporated that provide organized and timely guidelines to the current management of male infertility. The strength of evidence for treatment recommendations is also classified when appropriate.

Paternity following treatment for testicular cancer

BACKGROUND

Studies of fertility in men treated for testicular cancer have mainly addressed serum follicle-stimulating hormone levels and sperm parameters. We assessed post-treatment paternity among long-term survivors of testicular cancer.

METHODS

Men (n = 1814) who had been treated for unilateral testicular cancer in Norway during 1980 through 1994 were invited to participate in a national multi-center follow-up survey in 1998 through 2002. The participants were allocated to five groups according to the treatment received after orchiectomy, including treatment at relapse (surveillance, retroperitoneal lymph node dissection, radiotherapy, low-dose chemotherapy [i.e., < or = 850 mg cisplatin], and high-dose chemotherapy [i.e., > 850 mg cisplatin]). Cox proportional hazards analysis was used to assess predictive factors for post-treatment paternity. Statistical tests were two-sided.

RESULTS

A total of 1433 men were assessable, of whom 827 were fathers at diagnosis. Post-treatment conception was attempted by 554 men, among whom the overall 15-year actuarial post-treatment paternity rate was 71% (95% confidence interval [CI] = 66% to 75%) without the use of cryopreserved semen. This rate ranged from 48% (95% CI = 30% to 69%) in the high-dose chemotherapy group to 92% (95% CI = 78% to 98%) in the surveillance group (P < .001). The median actuarial time from diagnosis to the birth of the first child after treatment was 6.6 years overall but varied according to treatment. Assisted reproductive technologies were used by 22% of the couples who attempted conception after treatment. Dry ejaculation, treatment group, pretreatment fatherhood, and marital status were statistically significant independent predictors for post-treatment fatherhood, with dry ejaculation as the most important negative factor.

CONCLUSIONS

Although the overall paternity rate after treatment for testicular cancer was high, the ability to conceive and the time to conception reflected the intensity of treatment. These data may help inform patients about their future ability to father biological children.

Report from the Rockefellar Foundation Sponsored International Workshop on reducing mortality and improving quality of life in long-term survivors of Hodgkin's disease: July 9-16, 2003, Bellagio, Italy

A workshop, sponsored by the Rockefellar Foundation, was held between 9 to 16 July, 2003 to devise strategies to reduce mortality and improve quality of life of long-term survivors of Hodgkin's disease. Participants were selected for their clinical and research background on late effects after Hodgkin's disease therapy. Experts from both developed and developing nations were represented in the workshop, and efforts were made to ensure that the proposed strategies would be globally applicable whenever possible. The types of late complications, magnitude of the problem, contributing risk factors, methodology to assess the risk, and challenges faced by developing countries were presented. The main areas of late effects of Hodgkin's disease discussed were as follows: second malignancy, cardiac disease, infection, pulmonary dysfunction, endocrine abnormalities, and quality of life. This report summarizes the findings of the workshop, recommendations, and proposed research priorities in each of the above areas.

Fertility in males treated for Hodgkins disease with COPP/ABV hybrid

More than 80% of those diagnosed with Hodgkins disease (HD) will survive long-term. For the past decade, a modified hybrid consisting of cyclophosphamide (2.4-3.6g/m(2)), vincristine, procarbazine, and prednisone (COPP) together with adriamycin, bleomycin, and vinblastine (ABV) has been used to treat patients with HD. Little data exists on how this modified hybrid impacts male fertility. Eleven male patients treated with COPP-ABV hybrid were studied. Nine out of 11 subjects were categorized as infertile by semen analysis; 7 of 9 were azoospermic. There was no association between fertility status and prepubertal status at diagnosis or gonadotropin status. Despite lower doses of cyclophosphamide, treatment with the current COPP/ABV hybrid leads to infertility in the majority of young men. It is likely that procarbazine, an effective yet potent gonadotoxic agent, is responsible for this outcome.

Successful pregnancy outcome using sperm from severely diseased men with testicular cancer and collagen disease: Three case reports

Objective:  To confirm the feasibility of using fresh or frozen/thawed spermatozoa from cancer and collagen diseased patients for intracytoplasmic sperm injection (ICSI). Patients:  Two participants were diagnosed with testicular carcinoma and one patient was diagnosed with collagen disease. Methods:  Of the two carcinoma patients, one patient provided a fresh testicular biopsy sample and one patient ejaculated fresh sperm after surgical operation. One collagen diseased patient's sperm was frozen, and three samples were used in subsequent ICSI treatment cycles. Their female partners underwent controlled ovarian hyperstimulation for the retrieval of oocytes. Results:  Two patients with testicular cancer and their respective partners achieved successful pregnancies from ICSI using fresh sperm after surgery. The patient suffering from collagen disease had a successful pregnancy from ICSI using sperm frozen prior to chemotherapy treatment. Conclusions:  Patients with testicular carcinoma or collagen disease who might desire to father children in the future should be offered sperm preservation prior to the initiation of chemotherapy treatment. Under currently available treatment, patients with cases of severe disease can still become biological fathers. (Reprod Med Biol 2004; 3: 69-75).
