Abstract
For several years, fertility disorders have been on the increase worldwide. These disorders affect both sexes, but are more pronounced in men; and in half of cases the etiology is unknown. The role of drugs in male infertility has been little studied to date. Most of the available data comes from experimental animal studies, with all their limitations. With the exception of a few drugs, such as certain anticancer agents, human data are rare. This article describes the mainly drugs known to have deleterious effects on male fertility, the mechanisms leading to these effects and methods used to assess the risk of drug-induced male infertility. It underlines the need for further work in experimental research, clinical trials and post-marketing surveillance to improve our knowledge of drugs that induce male infertility. Although these adverse effects are not life-threatening, they can have a significant impact on patients' lives.

Abstract
STUDY QUESTION Does sperm cryopreservation serve as a feasible and effective method for preserving fertility in adult male patients with cancer? SUMMARY ANSWER Sperm cryopreservation is an effective fertility preservation method and may benefit patients with cancer. WHAT IS KNOWN ALREADY Sperm cryopreservation is the only way to efficiently preserve male fertility. It is an important procedure in ART. Recently, due to remarkable advances in cancer treatment, an increasing number of studies have reported the outcomes of sperm cryopreservation in patients with cancer. STUDY DESIGN SIZE DURATION We conducted an extensive literature search for relevant studies published through to 31 December 2021, in the following databases: CENTRAL, CNKI, Cochrane Systematic Reviews, EMBASE, MEDLINE, PUBMED, and Web of Science. The search terms used were '(cryopreservation OR freeze OR freezing OR banking OR cryostorage OR storage) AND (sperm OR semen OR spermatozoon) AND (cancer OR tumor OR malignancy OR neoplasm)'. PARTICIPANTS/MATERIALS SETTING METHODS We included all studies that reported offering or attempting to cryopreserve sperm before or during cancer treatment in male patients considered at risk of treatment-related fertility impairment. We evaluated the eligibility of all data in each study. The major exclusion criteria were as follows: non-cancer patients; pediatric and adolescent cancer patients; not reporting the use of cryopreserved sperm; use of fresh semen for ART; not reporting the number of patients with cancer offered sperm cryopreservation or attempting to do so before or during treatment; using an experimental fertility preservation technique such as preservation of testicular tissue or spermatogonial stem cells; duplicate data; abstracts, case report, comments, reviews, or editorials; insufficient data reported. The quality of the included studies was assessed using the Newcastle-Ottawa scale and the Methodological Index for Non-Randomized Studies. MAIN RESULTS AND THE ROLE OF CHANCE This meta-analysis included 69 non-randomized studies, with 32 234 patients referred for sperm analysis and 23 178 patients cryopreserving at least one sperm sample. The pooled failed-to-cryopreserve rate was 10% (95% CI, 8-12%), and the sperm disposal and sperm use rates were 23% (95% CI, 16-30%) and 9% (95% CI, 8-10%), respectively. The pregnancy, miscarriage, and delivery rates were 28% (95% CI, 22-33%), 13% (95% CI, 10-17%), and 20% (95% CI, 15-25%), respectively. Subgroup analysis showed higher pregnancy and delivery rates, as well as a lower failed-to-cryopreserve rate, in recent studies compared to those released a decade ago. The studies from Asia reported higher sperm disposal and pregnancy rates than in other continents. Our analysis showed clinical pregnancy rates per cycle of 34% (27-41%), 24% (14-35%), and 9% (5-15%) and delivery rates per cycle of 23% (17-30%), 18% (11-26%), and 5% (1-9%) for ICSI, IVF, and IUI, respectively. LIMITATIONS REASONS FOR CAUTION As with all meta-analyses, some limitations should be considered. The first limitation of our study is that the data span 36 years. During this time, the World Health Organization has revised its sperm analysis standards, and other important changes have been made. There is also a limitation in that the outcome does not analyze the correlation between the type of cancer and sperm quality. Many of the earlier studies were limited by small sample sizes and a lack of control groups. Furthermore, almost all studies did not consider the severity of the disease, which could potentially have a substantial impact on the results. Consequently, further research should evaluate the effect of the type of cancer and, in particular, the severity of the condition on sperm quality in order to draw more precise conclusions. Similarly, it is inappropriate that most studies failed to differentiate between patients with different types of tumors and instead drew generalized conclusions that are presumed to apply to all patients with cancer. In the present analysis, we did not have in-depth information on patients' disease, and although extensive efforts were made to conduct a thorough systematic review and meta-analysis of the outcomes for patients with various types of tumors, the results must be acknowledged as being subject to bias. However, the use of average results obtained in each study, without the patient-level data, might also represent a source of bias. WIDER IMPLICATIONS OF THE FINDINGS Sperm cryopreservation is an effective fertility preservation method and may benefit patients with cancer. The observed utilization rate of frozen sperm at 9% may underestimate the actual usage, as the short follow-up period is inadequate for obtaining comprehensive data on the use of frozen sperm in young cancer survivors. ART plays an important role in fertility preservation and the achievement of pregnancy, with this meta-analysis showing that ICSI delivers better clinical outcomes than IVF or IUI in patients with cancer undergoing fertility preservation.

Cancers (Basel) 2023; 15:5348. [PMID: 38001608 PMCID: PMC10670543 DOI: 10.3390/cancers15225348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 11/01/2023] [Accepted: 11/06/2023] [Indexed: 11/26/2023] Open
Abstract
BACKGROUND Many cancer treatment methods can affect fertility by damaging the reproductive organs and glands that control fertility. Changes can be temporary or permanent. In order to preserve the fertility of cancer patients and protect the genital organs against gonadotoxicity, methods of fertility preservation are increasingly used. Considering that some patients ultimately decide not to use cryopreserved reproductive material, this review analysed the percentage of post-cancer patients using cryopreserved reproductive material, collected before treatment as part of fertility preservation. METHODS A systematic search of studies was carried out in accordance with the Cochrane Collaboration guidelines, based on a previously prepared research protocol. The search was conducted in Medline (via PubMed), Embase (via OVID), and the Cochrane Library. In addition, a manual search was performed for recommendations/clinical practice guidelines regarding fertility preservation in cancer patients. RESULTS Twenty-six studies met the inclusion criteria. The studies included in the review discussed the results of cryopreservation of oocytes, embryos, ovarian tissue, and semen. In 10 studies, the usage rate of cryopreserved semen ranged from 2.6% to 21.5%. In the case of cryopreserved female reproductive material, the return/usage rate ranged from 3.1% to 8.7% for oocytes, approx. 9% to 22.4% for embryos, and 6.9% to 30.3% for ovarian tissue. In studies analysing patients' decisions about unused reproductive material, continuation of material storage was most often indicated. Recovering fertility or death of the patient were the main reasons for rejecting cryopreserved semen in the case of men. CONCLUSION Fertility preservation before gonadotoxic treatment is widely recommended and increasingly used in cancer patients. The usage rate is an important indicator for monitoring the efficacy of these methods. In all of the methods described in the literature, this indicator did not exceed 31%. It is necessary to create legal and organizational solutions regulating material collection and storage and to create clear paths for its usage in the future, including by other recipients.

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
With advances in cancer treatment, such as cytotoxic chemotherapy and radiotherapy, grave new sequelae of treatment have emerged for young cancer survivors. One sequela that cannot be overlooked is male infertility, with reportedly 15% to 30% of cancer survivors losing their fertility potential. Cytotoxic therapy influences spermatogenesis at least temporarily, and in some cases, permanently. The degree of spermatogenesis impairment depends on the combination of drugs used, their cumulative dose, and the level of radiation. The American Society of Clinical Oncology has created an index to classify the risks to fertility based on treatment. Medical professionals currently use this risk classification in fertility preservation (FP) programs. FP programs are currently being promoted to prevent spermatogenesis failure resulting from cancer treatment. For patients who are able to ejaculate and whose semen contains sperm, the semen (sperm) is cryopreserved. Moreover, for patients who lack the ability to ejaculate, those with azoospermia or severe oligozoospermia, and those who have not attained puberty (i.e., spermatogenesis has not begun), testicular biopsy is performed to collect the sperm or germ cells and cryopreserve them. This method of culturing germ cells to differentiate the sperm has been successful in some animal models, but not in humans. FP has recently gained popularity; however, some oncologists and medical professionals involved in cancer treatment still lack adequate knowledge of these procedures. This hinders the dissemination of information to patients and the execution of FP. Information sharing and collaboration between reproductive medicine specialists and oncologists is extremely important for the development of FP. In Japan, the network of clinics and hospitals that support FP is expanding across prefectures.

Abstract
OBJECTIVES To demonstrate that surgical sperm retrieval (SSR) and spermatogonial stem cell retrieval (SSCR) in an oncological context are safe and successful. PATIENTS AND METHODS This a retrospective study in a tertiary hospital in the UK. Patients requiring fertility preservation from December 2017 to January 2020 were included. Data were analysed with Microsoft Excel 2016 and the Statistical Package for the Social Sciences (version 20). RESULTS Among 1264 patients referred to the Reproductive Medical Unit at the University College of London Hospitals for cryopreservation prior to gonadotoxic treatment, 39 chose to go forward with SSR/SSCR because they presented as azoo-/cryptozoospermic or an inability to masturbate/ejaculate. Interventions were testicular sperm extraction (23 patients) or aspiration (one), electroejaculation (one), and testicular wedge biopsy for SSCR (14). The median (range) age was 15.0 (10-65) years and the median testosterone level was 4.4 nmoL/L. Primary diagnoses were sarcoma in 11 patients, leukaemia in nine, lymphoma in eight, testicular tumour in five, other oncological haematological entities in two, other solid cancers in two, while two patients had non-oncological haematological diseases. SSR/SSCR could be offered within 7.5 days on average. Chemotherapy could follow within 2 days from SSR/SSCR, and bone marrow transplant occurred within 19.5 days (all expressed as medians). The success rate for SSR was 68.0% (at least one vial/straw collected). The mean (SD) Johnsen score of testicular biopsies was 5.23 (2.25) with a trend towards positive correlation with SSR success (P = 0.07). However, age, hormonal profile and type of cancer did not predict SSR outcome. CONCLUSION We show that SSR and SSCR in an oncological context are valid treatment options with a high success rate for patients in which sperm cryopreservation from semen is impossible. By providing an effective pathway, fertility preservation is possible with minimal delay to oncological treatment.

Abstract
Purpose: Cancer and its treatment can impair fertility in men. It is recommended that they be referred for fertility consultation before the start of treatment. This study examined factors associated with men attending a fertility consultation within 30 days of diagnosis. Methods: Males 15 to 39 years of age, diagnosed with cancer in Ontario, Canada, between 2006 and 2019, were identified from the Ontario Cancer Registry. Linked administrative data were used to obtain other clinical and sociodemographic variables. The main outcome was a fertility consultation within 30 days of diagnosis, defined using Ontario Health Insurance Plan billing codes (606 or 628). A backward selection multivariate logistic regression was performed. Results: Of 13,720 cases identified, 8.5% attended a fertility consultation within 30 days of diagnosis. A more recent year of diagnosis (odds ratio [OR] = 5.5; 95% confidence interval [CI] 4.6-6.6), living in an urban area (OR = 1.3; 95% CI 1.0-1.8), receiving radiation therapy (OR = 1.4; 95% CI 1.2-1.6), chemotherapy (OR = 1.9; 95% CI 1.6-2.2), and reproductive organ-related cancer surgery (OR = 1.5; 95% CI 1.2-1.7) were associated with a greater likelihood of attending a consultation. Older age (OR = 0.2; 95% CI 0.1-0.2), living in a northern region (OR = 0.3; 95% CI 0.2-0.5), having a cancer with low (OR = 0.3; 95% CI 0.2-0.4) or moderate risk to fertility (OR = 0.6; 95% CI 0.5-0.7), and residing in a neighborhood with lower income (OR = 0.4; 95% CI 0.3-0.5) or residential instability quintile (OR = 0.8; 95% CI 0.6-1.0) were associated with being less likely to attend a consultation. Conclusion: Although rates of fertility consultation have increased over time, these remain low in various clinical and demographic groups. Funding for fertility preservation appears to have had an important impact on fertility consultation in young men with cancer.

Abstract
Acute myeloid leukemia (AML) accounts for around 20% of diagnosed childhood leukemia. Cytarabine (CYT) is involved in the AML treatment regimen. AML and CYT showed impairment in spermatogenesis in human and rodents in adulthood. We successfully developed an AML disease model in sexually immature mice. Monocytes and granulocytes were examined in all groups: untreated control, AML alone, CYT alone and AML+CYT (in combination). There was a significant increase in the counts of monocytes and granulocytes in the AML-treated immature mice (AML) compared to the control, and AML cells were demonstrated in the blood vessels of the testes. AML alone and CYT alone impaired the development of spermatogenesis at the adult age of the AML-treated immature mice. The damage was clear in the structure/histology of their seminiferous tubules, and an increase in the apoptotic cells of the seminiferous tubules was demonstrated. Our results demonstrated a significant decrease in the meiotic/post-meiotic cells compared to the control. However, CYT alone (but not AML) significantly increased the count of spermatogonial cells (premeiotic cells) that positively stained with SALL4 and PLZF per tubule compared to the control. Furthermore, AML significantly increased the count of proliferating spermatogonial cells that positively stained with PCNA in the seminiferous tubules compared to the control, whereas CYT significantly decreased the count compared to the control. Our result showed that AML and CYT affected the microenvironment/niche of the germ cells. AML significantly decreased the levels growth factors, such as SCF, GDNF and MCSF) compared to control, whereas CYT significantly increased the levels of MCSF and GDNF compared to control. In addition, AML significantly increased the RNA expression levels of testicular IL-6 (a proinflammatory cytokine), whereas CYT significantly decreased testicular IL-6 levels compared to the control group. Furthermore, AML alone and CYT alone significantly decreased RNA expression levels of testicular IL-10 (anti-inflammatory cytokine) compared to the control group. Our results demonstrate that pediatric AML disease with or without CYT treatment impairs spermatogenesis at adult age (the impairment was more pronounced in AML+CYT) compared to control. Thus, we suggest that special care should be considered for children with AML who are treated with a CYT regimen regarding their future fertility at adult age.

Abstract
Background Many studies have reported that testicular germ cell tumours (TGCTs) give rise to a decrease in sperm production and may further lead to infertility. However, little is known regarding sperm production in extragonadal germ cell tumours (EGCTs). We have studied the differences in the characteristics and sperm quality of patients with testicular cancer and patients with EGCTs. Methods We collected and analysed demographic factors, semen parameters, and the disposition of banked sperm. Results TGCTs accounted for the majority of malignant cancers compared with EGCTs (83.9% vs. 16.1%, respectively). There were no statistically significant differences in semen volume, pre-freeze concentration, pre-freeze motility, post-thaw concentration, post-thaw motility or recovery rate between patients with TGCTs and those with EGCTs. Both patients with TGCTs and EGCTs showed low pre-freeze and post-thaw sperm concentrations. Men with a seminoma had a higher median level of thaw-sperm motility in their ejaculate than men with non-seminomas. TGCT (67%) and EGCT (72%) patients chose to keep their specimens in storage. Conclusions Our study provides evidence that both patients with TGCTs and EGCTs have a high risk for impaired semen quality and gonadal dysfunction. This suggests that oncologists and patients should consider the effects of both TGCTs and EGCTs on fertility among males.

Abstract
Background Newly emerging serious post‐treatment complications among young male cancer survivors involve fertility and sexual function, preventing them from pursuing a normal family life. Methods We studied and summarized published studies that assess the relationship between cancer treatments and reduced spermatogenesis or sexual dysfunction. Main findings Infertility often occurs because of anticancer therapies that impair spermatogenesis. While some patients postremission functionally recover fertility, others experience a decreased sperm count and azoospermia. Fertility‐preserving modalities are currently being promoted worldwide to preserve spermatogenesis following cancer therapy. Patients who can ejaculate and have sperm in their semen should cryopreserve semen. However, for patients who have never ejaculated before puberty or in whom spermatogenesis has not been established, testis biopsy is performed to collect and preserve sperm or germ cells. Fertility preservation is gaining popularity and requires continuous information dissemination to oncologists and cancer treatment professionals. Furthermore, male sexual dysfunction predominantly involves erectile dysfunction and ejaculation disorder. Conclusion Although preventive and therapeutic methods for these disorders have been established within urology, patients and medical professionals in other fields remain uninformed of these advances. Therefore, dissemination of information regarding fertility preservation techniques should be accelerated.

Int J Mol Sci 2021; 22:ijms222011157.

Abstract
Leukemia and treatment of male patients with anticancer therapy (aggressive chemotherapy and/or radiotherapy) may lead to infertility or even permanent male sterility. Their mechanisms of spermatogenesis impairment and the decrease in male fertility are not yet clear. We showed that under acute myeloid leukemia (AML) conditions, alone and in combination with cytarabine (CYT), there was significant damage in the histology of seminiferous tubules, a significant increase in apoptotic cells of the seminiferous tubules, and a reduction in spermatogonial cells (SALL and PLZF) and in meiotic (CREM) and post-meiotic (ACROSIN) cells. In addition, we showed a significant impairment in sperm parameters and fertilization rates and offspring compared to control. Our results showed a significant decrease in the expression of glial cell line-derived neurotrophic factor (GDNF), macrophage colony-stimulating factor (MCSF) and stem cell factor (SCF) under AML conditions, but not under cytarabine treatment compared to control. In addition, our results showed a significant increase in the pro-inflammatory cytokine interleukin-1 (IL-1) alpha in whole testis homogenates in all treatment groups compared to the control. Increase in IL-1 beta level was shown under AML conditions. We identified for the first time the expression of GCSF receptor (GCSFR) in sperm cells. We showed that GCSF injection in combination with AML and cytarabine (AML + CYT + GCSF) extended the survival of mice for a week (from 6.5 weeks to 7.5 weeks) compared to (AML + CYT). Injection of GCSF to all treated groups (post hoc), showed a significant impact on mice testis weight, improved testis histology, decreased apoptosis and increased expression of pre-meiotic, meiotic and post- meiotic markers, improved sperm parameters, fertility capacity and number of offspring compared to the controls (without GCSF). GCSF significantly improved the spermatogonial niche expressed by increased the expression levels of testicular GDNF, SCF and MCSF growth factors in AML-treated mice and (AML + CYT)-treated mice compared to those groups without GCSF. Furthermore, GCSF decreased the expression levels of the pro-inflammatory cytokine IL-12, but increased the expression of IL-10 in the interstitial compartment compared to the relevant groups without GCSF. Our results show for the first time the capacity of post injection of GCSF into AML- and CYT-treated mice to improve the cellular and biomolecular mechanisms that lead to improve/restore spermatogenesis and male fertility. Thus, post injection of GCSF may assist in the development of future therapeutic strategies to preserve/restore male fertility in cancer patients, specifically in AML patients under chemotherapy treatments.

Abstract
Background Sperm cryopreservation, an effective method for preserving male fertility, is very advantageous for men suffering from cancer. Unfortunately, as both physicians and cancer patients are unaware of the possibilities for sperm cryopreservation, the data on evaluation of semen parameters and disposition of cryopreserved samples among Chinese cancer patients are scarce. Results Male tumours were classified into six major types, germ cell tumours (26 %), haematological neoplasms (28 %), head and neck cancers (19 %), thoracic tumours (4 %), abdominal tumours (10 %), and others (13 %). Haematological neoplasm was the most prevalent cancer among our cohort of patients who opted for sperm banking, followed by germ cell tumours. Patients with germ cell tumours had the lowest pre-thaw and post-thaw seminal sperm concentrations. We separately compared patients with testicular tumours, lymphoma, and leukaemia, and found that leukaemia patients had the lowest pre-thaw sperm concentrations. Most cancer patients (58 %) chose to keep their specimens stored, while 31 % chose to discard the specimens. Over the years, only 13 patients (4 %) returned to use their spermatozoa by assisted reproductive technology. Of the stored samples, patients with germ cell tumours constituted the highest proportion (29.3 %). Moreover, the percentage of haematological neoplasm patients who had no spermatozoa frozen was the highest (46.2 %). Conclusions The present data confirm the deleterious impact of various cancers on semen quality. Leukaemia was associated with the worst semen quality and the highest number of semen samples that could not be frozen. We suggest that sperm quality may have decreased even before anti-neoplastic treatment and that sperm banking before treatment should be strongly recommended for cancer patients. A sperm banking programme before gonadotoxic therapy requires close cooperation between assisted reproduction centres and cancer clinics.

The outcome of IVF/ICSI cycles in male cancer patients: retrospective analysis of procedures from 2004 to 2018. Radiol Oncol 2021; 55:221-228. [PMID: 33675201 PMCID: PMC8042825 DOI: 10.2478/raon-2021-0011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Accepted: 01/25/2021] [Indexed: 11/20/2022] Open
Abstract
Introduction Fertility preservation is an important aspect of quality of life in oncological patients, and in men is achieved by semen cryopreservation prior to treatment. Results of in vitro fertilization (IVF) procedures in healthy infertile couples are comparable, regardless of whether fresh or cryopreserved semen is used, but are scarce in male oncological patients. Patients and methods We performed a retrospective analysis of IVF/intracytoplasmic sperm injection (IVF/ICSI) procedures in infertile couples where men had been treated for cancer in the past. We additionally compared the results of IVF/ICSI procedures with respect to the type of semen used (fresh, cryopreserved). Results We compared the success rates of 214 IVF/ICSI cycles performed in the years 2004–2018. Pregnancy (30.0% vs. 21.4%; p = 0.12) and live-birth rates (22.3% vs. 17.9%; p = 0.43) per oocyte aspiration were similar between the groups in fresh cycles; however embryo utilization (48.9% vs. 40.0%; p = 0.006) and embryo cryopreservation rates (17.3% vs. 12.7%; p = 0.048) were significantly higher in the cryopreserved semen group. The cumulative pregnancy rate (60.6% vs. 37.7%; p = 0.012) was significantly higher, and the live-birth rate (45.1% vs. 34.0%; p = 0.21) non-significantly higher, in the cryopreserved semen group. Conclusions The success of IVF/ICSI procedures in couples where the male partner was treated for cancer in the past are the same in terms of pregnancies and live-births in fresh cycles regardless of the type of semen used. However, embryo utilization and embryo cryopreservation rates are significantly higher when cryopreserved semen is used, leading to a significantly higher cumulative number of couples who achieved at least one pregnancy.

Abstract
The prolonged lockdown of health facilities providing non‐urgent gamete cryopreservation—as currently recommended by many reproductive medicine entities and regulatory authorities due to the SARS‐CoV‐2 pandemic will be detrimental for subgroups of male infertility patients. We believe the existing recommendations should be promptly modified and propose that the same permissive approach for sperm banking granted for men with cancer is expanded to other groups of vulnerable patients. These groups include infertility patients (eg, azoospermic and cryptozoospermic) undergoing medical or surgical treatment to improve sperm quantity and quality, as well as males of reproductive age affected by inflammatory and systemic auto‐immune diseases who are about to start treatment with gonadotoxic drugs or who are under remission. In both scenarios, the “fertility window” may be transitory; postponing diagnostic semen analysis and sperm banking in these men could compromise the prospects of biological parenthood. Moreover, we provide recommendations on how to continue the provision of andrological services in a considered manner and a safe environment. Our opinion is timely and relevant given the fact that fertility services are currently rated as of low priority in most countries.

Abstract
AbstractActive duty military service and deployment has the potential to compromise fertility through combat-related genitourinary injury, gonadotoxic exposures, and physical separation from a partner. Despite a growing interest among the military community as well as promising efficacy and safety data, fertility preservation remains an uncovered benefit for active duty soldiers. In 2016, the Pentagon proposed a program that would cover oocyte and sperm cryopreservation for any member of the active duty military desiring its use. Regrettably, that funding was not secured and predeployment fertility preservation remains an out-of-pocket expense. Today, advocacy groups, non-for-profit organizations, and physicians remain vigilant in their attempts to drive another government initiative through Congress. While activism continues, it is important to stress the value of fertility preservation counseling in soldiers' predeployment preparation and military family planning.

Abstract
This study aimed to ascertain the current status of Japanese sperm banking for young cancer patients. During 2015, we mailed the directors of 695 institutes where sperm cryopreservation might be performed with questionnaires requesting information on the number of patients, age, precryopreservation chemotherapy, semen analyses results and diagnoses, cryopreservation success rate, and causes of unsuccessful cryopreservation. Of these 695 institutes, 92 had cryopreserved sperm before chemotherapy within the study period. In all, 820 cancer patients (237 testicular, 383 hematological, 46 bone and soft tissue, 20 brain, and 134 other malignancy) consulted the responding institutes for sperm cryopreservation. Except for testicular tumor, the number of patients whose sperm was preserved before cancer treatment was low compared to that of young cancer patients. Approximately 20% of patients with malignancies other than testicular tumor underwent chemotherapy before cryopreservation. The success rate of cryopreservation in hematological malignancy was 82.5%, significantly lower than that of both the testicular cancer (93.6%) and other malignancy groups (95.6%) (P < 0.05). The primary reasons for preservation failure were azoospermia and poor semen quality. Patients with hematological malignancies had a higher rate of unsuccessful cryopreservation compared to those in other groups, possibly due to the large number of patients requesting sperm cryopreservation after chemotherapy induction. In Japan, information regarding sperm banking prior to cancer treatment appears to be lacking. Information regarding sperm preservation before chemotherapy should be provided to all Japanese oncologists.

Abstract
Gender dysphoria, or the incongruence between gender identification and sex assigned at birth with associated discomfort or distress, manifests in transgender patients, whose multifaceted care includes puberty suppression, cross-sex hormonal therapy, and gender-affirming surgery. Discussion of fertility preservation (FP) is paramount because many treatments compromise future fertility, and although transgender patients demonstrate desire for children, use of FP remains low for a plethora of reasons. In transgender women, established FP options include ejaculated sperm cryopreservation, electroejaculation, or testicular sperm extraction. Further research is needed regarding reproductive health and FP in transgender patients.

Abstract
Leukemia is one of the most common cancers in patients of reproductive age. It is well known that chemotherapy, used as anti-cancer therapy, adversely affects male fertility. Moreover, the negative effect of leukemia on sperm quality, even before chemotherapy treatment, has been reported. However, the mechanisms behind this disease's effect on sperm quality remains unknown. In this study, we examine the direct effect of leukemia and chemotherapy alone and in combination on sperm parameters and male fertility. For this, we developed an acute myeloid leukemia (AML) mouse model (mice were treated with AML cells C1498 and developed leukemia); these mice then received cytarabine chemotherapy. Our findings reveal a significant reduction in sperm concentration and motility and a significant increase in abnormal morphology and spontaneous acrosome reaction of the sperm following AML and chemotherapy treatment, alone and in combination. We also found a reduction in male fertility and the number of delivered offspring. Our results support previous findings that AML impairs sperm parameters and show for the first time that AML increases spontaneous acrosome reaction and decreases male fertility capacity and number of offspring.

Abstract
Spermatogenesis is the process of the proliferation and differentiation of spermatogonial stem cells (SSCs) to generate sperm. Leukemia patients show impairment in some of the endocrine hormones that are involved in spermatogenesis. They also show a decrease in semen parameters before and after thawing of cryopreserved samples compared to a control. The mechanisms behind these effects have not yet been described. This review summarizes the effect of leukemia on semen parameters from adult patients and highlights feasible suggested mechanisms that may affect impairment of spermatogenesis in these patients. We suggest the possible involvement of leukemia in disturbing hormones involved in spermatogenesis, and the imbalance in testicular paracrine/autocrine factors involved in the formation of SSC niches that control their proliferation and differentiation. Understanding the mechanisms of leukemia in the impairment of spermatogenesis may lead to the development of novel therapeutic strategies mainly for prepubertal boys who do not yet produce sperm.

Abstract
BACKGROUND Treatment advancements have improved young cancer patients' survival rate considerably. Fertility preservation has become a very important tool in the prevention of treatment-induced gonadal toxicity. This study aimed to examine hematologists' awareness of its necessity and importance. METHODS Questionnaires were mailed to the directors of 230 institutes that treated hematological malignancies in adults. The directors were asked to provide information regarding their institutes, collaboration with sperm banks, the number of patients treated per year, selection criteria for patients providing information, and their awareness of and attitudes toward sperm preservation. RESULTS The response rate was 40.0%. Municipal and private hospitals treated patients significantly less frequently relative to university hospitals (p = .002). Of the 92 participating hematology institutions, 17 included sperm banks and 69 collaborated with sperm banks in neighboring institutions. Many participants stated that sperm preservation should be performed before chemotherapy; however, only 38% provided sperm preservation information to all patients. Participants in facilities without sperm banks exhibited significantly lower levels of knowledge regarding sperm preservation, relative to those from institutions with sperm banks, and found discussing fertility preservation burdensome. This trend was identical to that observed in a survey conducted 10 years earlier. CONCLUSION Many hematologists did not appear to possess sufficient knowledge regarding fertility preservation. Moreover, few institutions included sperm banks, and a considerable burden was exerted on hematologists. The introduction of support systems is required to promote sperm preservation before cancer treatment.

Abstract
Adolescent and young adult (AYA) cancer patients under 40 should be made aware of their fertility risks and preservation options throughout their care. However, discussions on fertility preservation (FP) do not routinely occur. With a dearth of FP resources, oncology providers may lack knowledge around FP. Thus, informational needs can be unmet, leading to anxiety and distress in patients. Provision of pertinent and timely information can help patients cope better with their diagnosis. FP pamphlets were developed for men and women with cancer. A cross-sectional in-house survey, using convenience sampling, evaluated the pamphlets' effectiveness and measured ease of understanding, acceptability, and perceived utility. Patients and partners were also asked to provide recommendations and complete the Short Test of Functional Health Literacy in Adults (S-TOFHLA) measuring health literacy level. This helps determine if health literacy influences perception of pamphlet effectiveness. All participants (n = 56) reviewed both pamphlets. Fifty-four participants (96 %) found the pamphlet for men useful, while 29 participants (52 %) improved their male fertility knowledge. The pamphlet for women was useful for 52 participants (93 %) and improved knowledge in 35 (63 %) of them. Although the majority of participants had adequate health literacy (98 %), there was insufficient sample diversity to determine if health literacy influenced the pamphlet's effectiveness. Participants indicated preference in receiving verbal (73 %) and written (66 %) information over watching videos or in-class education. They recommended including fertility clinics, financial resources, and statistics in the brochures. These FP pamphlets were concluded as effective in supporting patients in making FP decisions.

Abstract
Purpose Cryopreservation of sperm from human semen has been available since the 1950s. The actual utilization of available cryopreservation technology has been infrequently reported. We set out to examine the utilization and outcomes of cryopreserved sperm cells based on the indication for storage. Materials and Methods A dataset was developed from retrospective review. The purposes for cryopreservation, eventual utilization, and outcomes of use for insemination were recorded. The types of utilization were accumulated as proportions for different purposes. The timing for use of samples for insemination procedures was evaluated using survival statistics. The frequency of patients arranging to destroy samples was also reported. Results From September 1988 through March 2015, 1442 samples were cryopreserved. Samples were cryopreserved for four primary purposes: infertility treatments focused on intrauterine insemination (IUI) or in vitro fertilization/intracellular injection (IVF/ICSI), for fertility preservation related to cancer treatment, or prior to military deployment. Total utilization rates were 19.3%. Samples cryopreserved for IUI were more likely to be used (64.3%), while samples cryopreserved as backup for IVF/ICSI were more likely to be destroyed (29.8%). Pregnancy rates varied based on the indication and ART used. Pregnancies per cycle were 35% for IVF/ICSI and were 10% for IUI. Conclusions Cryopreservation of sperm is a valuable and underutilized resource, particularly amongst male cancer patients. This technology can facilitate infertility treatments based on a variety of indications, including deployment-a patient cohort unique to our dataset.

Abstract
Background Testicular cancer (TC) is one of the most common malignancies in young men of reproductive age. Although TC is a curable malignancy with a high survival rate, its treatment requires various cytotoxic modalities and negatively impacts spermatogenesis; therefore, the fertility preservation of patients with TC has been studied. Methods In order to give an overview of fertility preservation in patients with TC, the literature was reviewed. Original and review articles were identified and examined on the basis of PubMed database searches. Results Chemotherapy and radiotherapy damage spermatogenesis and retroperitoneal lymph node dissection negatively impacts ejaculatory function. Testicular sperm extraction facilitates successful sperm retrieval in patients with TC with postchemotherapy azoospermia. Although preserved sperm is used with a very low frequency (8%), the conception rates in those who have used sperm are not inferior. Conclusion The number of studies is limited, and because numerous treatment factors affect fertility, outstanding questions remain about preserving the fertility of patients with TC. Further studies are necessary in order to determine the best means of preventing and treating infertility in patients with TC.

Abstract
As survival rates and the life expectancy of those with malignancy have increased, more women in their reproductive years are referred for fertility preservation. Chemotherapy and radiotherapy can severely affect ovarian function, and the effect is irreversible. Therefore, it is optimal to attempt fertility preservation before chemotherapy and radiotherapy are initiated. Oocyte and embryo cryopreservation is the most common option for fertility preservation in women. Several reports have proven that embryo and oocyte cryopreservation can achieve a successful pregnancy. This review discusses the impact of chemotherapy and radiotherapy on ovarian function, and the importance of oocyte and embryo cryopreservation for fertility preservation. In addition, the current status of pregnancy outcomes and potential for cryopreserved oocytes to result in live births in cancer patients was reviewed. This may provide useful information for decision-making in cancer patients regarding oocyte and embryo cryopreservation and fertility preservation.

Abstract
In recent years, survival rates of cancer patients have increased, resulting in a shift of focus from quantity to quality of life. A key aspect of quality of life is fertility potential; patients suffering from iatrogenic infertility often become depressed. Since many cancer therapies—chemotherapy, radiotherapy and/or surgery—and even cancer itself have detrimental effects on the male reproductive system, it is important to preserve fertility before any treatment commences. Currently, the only reliable method of male fertility preservation is sperm banking. For patients who are unable to provide semen samples by the conventional method of masturbation, there are other techniques such as electroejaculation, microsurgical epididymal sperm aspiration and testicular sperm extraction that can be employed. Unfortunately, it is presently impossible to preserve the fertility potential of pre-pubertal patients. Due to the increasing numbers of adolescent cancer patients surviving treatment, extensive research is being conducted into several possible methods such as testicular tissue cryopreservation, xenografting, in vitro gamete maturation and even the creation of artificial gametes. However, in spite of its ease, safety, convenience and many accompanying benefits, sperm banking remains underutilized in cancer patients. There are several barriers involved such as the lack of information and the urgency to begin treatment, but various measures can be put in place to overcome these barriers so that sperm banking can be more widely utilized.

Utilization of sperm banking and barriers to its use in testicular cancer patients. Support Care Cancer 2015; 23:2763-8. [PMID: 25680764 DOI: 10.1007/s00520-015-2641-9] [Citation(s) in RCA: 42] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2014] [Accepted: 01/28/2015] [Indexed: 10/24/2022]
Abstract
PURPOSE Testicular cancer is the most common carcinoma in 20- to 40-year-old men. Eighty percent of patients with metastases achieve disease-free status with chemotherapy with or without surgical resection. Standard first-line chemotherapy is bleomycin, etoposide, and cisplatin (BEP) for three to four courses or etoposide and cisplatin (EP) for four courses. Forty percent of patients receiving chemotherapy will have permanently reduced sperm counts impairing future fertility. Sperm banking is an effective method of maintaining fertility. This retrospective study was performed to assess utilization and results from sperm banking, as well as the barriers to its use. METHODS Patients 18 and older who had received chemotherapy were given a five-item questionnaire on follow-up visit. This questionnaire included a mix of quantitative and qualitative questions. RESULTS Two hundred patients enrolled in the study, and all 200 completed the questionnaire. Of the two hundred, 139 (70 %) patients chose not to bank sperm; 71 (51 %) of those were not interested, 25 (18 %) declined due to desire to start chemotherapy, 24 (17 %) were not offered, 12 (9 %) declined due to cost, and 7 (5 %) answered "other." The average age at cancer diagnosis of patients who banked sperm was 28.4 as opposed to 32.6 for patients who did not (p = 0.003). The percentage of patients that had children before their diagnosis was 21 % in the sperm banking group, and 50 % in the group that did not (p = 0.0002). Sixty-one (30 %) chose to bank sperm; 11 of 61 patients (18 %) utilized the banked sperm; 9 of 11 (82 %) patients that utilized were successful; and 3 of 9 (33 %) successes resulted in multiple gestations. CONCLUSIONS Sperm banking provides the opportunity for paternity in testicular cancer patients with reduced sperm counts following treatment. However, the majority of these patients chose not to bank sperm or were not offered the opportunity. A range of factors such as time, emotional state, patient age, disease stage, prior children, institutional practices, and cost all influence whether banking is offered to patients and taken up. The authors provide recommendations to help clinicians overcome some of these barriers.

Abstract
Regenerative medicine has opened new avenues for treating patients with severe reproductive system disorders, such as congenital abnormalities, cancer, trauma, infection, inflammation and iatrogenic injuries. Over the past two decades, scientists have advanced the field of reproductive tissue engineering to restore normal sexual function and preserve fertility in both female and male patients. In this review, we summarize recent advances in the use of cell, tissue, and organ-based regenerative medicine strategies for clinical application in reproductive system disorders.

Abstract
In modern livestock breeding, cryopreserved semen is routinely used for artificial insemination. Sperm cryopreservation secures future reproduction, and insemination doses can be easily shipped. Processing of semen for cryopreservation can be done with minimal efforts and relatively low costs. In this chapter we describe the entire cryopreservation process for stallion and bull sperm including dilution of sperm in primary and freezing extender, cooling and packaging in straws, freezing in liquid nitrogen vapor, cryogenic storage, and thawing. Special emphasis is given on preparation of commonly used primary and freezing extenders (skim milk extender "INRA-82", TRIS-egg yolk extender "TEY") used in a two-step dilution approach. Furthermore the different cooling rates needed in different temperature regimes during the freezing process are being described. Cryopreservation procedures are described in case of using both specialized automated equipment and simple equipment.

Assisted reproductive outcomes of male cancer survivors. J Cancer Surviv 2014; 9:208-14. [PMID: 25272983 DOI: 10.1007/s11764-014-0398-7] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2014] [Accepted: 08/25/2014] [Indexed: 10/24/2022]
Abstract
PURPOSE The objective of our study was to evaluate the reproductive outcome of male cancer survivors treated with intracytoplasmic sperm injection (ICSI) using cryopreserved sperm and compare it with the same treatment in non-cancer males. METHODS We retrospectively analyzed database derived from cancer and non-cancer patients undergoing sperm cryopreservation from August 2008 to August 2012 at a university-based center. We evaluated the reproductive outcome of those cancer and non-cancer patients that had frozen sperm and returned subsequently to the clinic for assisted reproduction. RESULTS We studied 272 males with cancer and 296 infertile males. The most prevalent types of cancer in our cohort were lymphoma (25.3 %), testicular cancer (19.2 %), leukemia (7.3 %), and other malignancies including sarcoma, gastrointestinal, and central nervous system malignancies (48.2 %). The use rate of cryopreserved sperm was 10.7 % for cancer patients and 30.7 % for non-cancer patients. The mean age of males with cancer who returned to the clinic for fertility treatment was 36.7 ± 6 years, and the diagnoses were testis cancer (43.4 %), lymphoma (36.9 %), leukemia (13 %), and other malignancies (6.7 %). Live birth rate of the cancer cohort was 62.1 %, which was higher than that of the normospermic non-cancer population (p < 0.0047). CONCLUSIONS The use rate of cryopreserved sperm from oncofertility preservation cases is at around 10 %. The live birth rate using assisted reproductive technologies among these patients is at least comparable to that of the non-cancer population. IMPLICATIONS FOR CANCER SURVIVORS To our knowledge, this was the first comparative study of male cancer survivors treated with ICSI using cryopreserved sperm, which were compared to non-cancer males undergoing the same treatment. Male fertility preservation is a highly valued service that should be strongly encouraged prior to beginning cytotoxic cancer treatment. These results can help healthcare professionals in oncology to improve the quality of counseling on fertility preservation when managing young men with newly diagnosed cancer that require gonadotoxic treatment.

Abstract
This paper examines the relatively recent practice of non-medical egg freezing, in which women bank their eggs for later use in conceiving a child. Non-medical egg freezing has only been available for about the last five years, as new vitrification techniques have made the success rates for actual conception more reliable than the earlier method of slow freezing. I draw on interviews with both clinicians and women who have banked their eggs to consider how this novel practice articulates with broader issues about the relationship between sexuality, reproduction and the political economy of household formation. Non-medical egg-freezing provides a technical solution to a number of different problems women face with regard to the elongation of the life course, the extension of education, the cost of household establishment and the iterative nature of relationship formation, thematised by the ubiquity of internet dating among the interviewees. I focus on the ways women used egg freezing to manage and reconcile different forms of time.
