RESUMO

We aimed to compare the sperm quality in different cancer types and benign diseases before gonadotoxic treatment, and assess the usage rate of cryopreserved sperm for assisted reproductive treatment (ART). This retrospective study was conducted at two university clinics between January 2008 and July 2018. A total of 545 patients suffering from cancer or benign diseases were included in the study. The pretreatment sperm analyses were based on the World Health Organization (WHO) guidelines. Patients with testicular malignancy (TM) showed a significantly lower sperm count (median [interquartile range]: 18.7 × 106 [5.3 × 106-43.0 × 106] ml-1; P = 0.03) as well as total sperm count (42.4 × 106 [13.3 × 106-108.5 × 106] per ejaculate; P = 0.007) compared to other malignant and benign diseases. In addition, patients with nonseminomatous TM showed the lowest sperm count (14.3 × 106 [6.0 × 106-29.9 × 106] ml-1, vs seminomas: 16.5 × 106 [4.6 × 106-20.3 × 106] ml-1; P = 0.001). With reference to the WHO 2010 guidelines, approximately 48.0% of the patients with TM and 23.0% with hematological malignancies (HM) had oligozoospermia. During the observation period, only 29 patients (5.3%) used their frozen sperms for 48 ART cycles, resulting in 15 clinical pregnancies and 10 live births. The sperm quality varies with the type of underlying disease, with TM and HM patients showing the lowest sperm counts. Due to the observed low usage rate of cryopreserved sperm, further patient interviews and sperm analyses should be included in the routine oncologic protocols to avoid unnecessary storage expenses. However, sperm banking is worth the effort as it provides hope for men who cannot reproduce naturally after gonadotoxic treatment.

RESUMO

Purpose To estimate the prevalence of sperm banking among adolescent males newly diagnosed with cancer and to identify factors associated with banking outcomes. Patients and Methods A prospective, single-group, observational study design was used to test the contribution of sociodemographic, medical, psychological/health belief, communication, and developmental factors to fertility preservation outcomes. At-risk adolescent males (N = 146; age 13.00 to 21.99 years; Tanner stage ≥ 3), their parents, and medical providers from eight leading pediatric oncology centers across the United States and Canada completed self-report questionnaires within 1 week of treatment initiation. Multivariable logistic regression was used to calculate odds ratios (ORs) and 95% CIs for specified banking outcomes (collection attempt v no attempt and successful completion of banking v no banking). Results Among adolescents (mean age, 16.49 years; standard deviation, 2.02 years), 53.4% (78 of 146) made a collection attempt, with 43.8% (64 of 146) successfully banking sperm (82.1% of attempters). The overall attempt model revealed adolescent consultation with a fertility specialist (OR, 29.96; 95% CI, 2.48 to 361.41; P = .007), parent recommendation to bank (OR, 12.30; 95% CI, 2.01 to 75.94; P = .007), and higher Tanner stage (OR, 5.42; 95% CI, 1.75 to 16.78; P = .003) were associated with an increased likelihood of a collection attempt. Adolescent history of masturbation (OR, 5.99; 95% CI, 1.25 to 28.50; P = .025), banking self-efficacy (OR, 1.23; 95% CI, 1.05 to 1.45; P = .012), and parent (OR, 4.62; 95% CI, 1.46 to 14.73; P = .010) or medical team (OR, 4.26; 95% CI, 1.45 to 12.43; P = .008) recommendation to bank were associated with increased likelihood of sperm banking completion. Conclusion Although findings suggest that banking is underutilized, modifiable adolescent, parent, and provider factors associated with banking outcomes were identified and should be targeted in future intervention efforts.

RESUMO

OBJECTIVE: To identify and analyze existing posthumous sperm procurement (PSP) protocols in order to outline central themes for institutions to consider when developing future policies. DESIGN: Qualitative content analysis. SETTING: Large academic institutions across the United States. PATIENT(S) N/A INTERVENTION(S): We performed a literature search and contacted 40 institutions to obtain nine full PSP protocols. We then performed a content analysis on these policies to identify major themes and factors to consider when developing a PSP protocol. MAIN OUTCOME MEASURE(S): Presence of a PSP policy. RESULT(S): We identified six components of a thorough PSP protocol: Standard of Evidence, Terms of Eligibility, Sperm Designee, Restrictions on Use in Reproduction, Logistics, and Contraindications. We also identified two different approaches to policy structure. In the Limited Role approach, institutions have stricter consent requirements and limit their involvement to the time of procurement. In the Family-Centered approach, substituted judgment is permitted but a mandatory wait period is enforced before sperm use in reproduction. CONCLUSION(S): Institutions seeking to implement a PSP protocol will benefit from considering the six major building blocks of a thorough protocol and where they would like to fall on the spectrum from a Limited Role to a Family-Centered approach.

RESUMO

Existing research into sperm banking by young males following a cancer diagnosis is predominantly quantitative; little is known about personal experiences, psychosocial and attitudinal barriers to it amongst patients and/or professionals, or the later impact of potential or actual subfertility when banking has or has not taken place. This qualitative study used single in-depth interviews with 16 males aged 13 to 20 at diagnosis (16 to 30 years at interview) to report retrospectively on their experiences, concerns and satisfactions. There was support for sperm banking, including among those who declined to bank or failed to do so successfully. Many reported that, when successful, it eased any later fertility-related concerns by offering a possible alternative route to biological fatherhood. There was satisfaction with levels of understanding, recall and decision making, though lack of clarity about consent conditions. Sperm bank professionals were less likely than oncology staff to achieve good rapport. Improvements to consent arrangements, facilities, written information and sharing of results were suggested. Small numbers from minority ethnic or disabled communities meant that any uniqueness in their experiences could not be identified. While some improvements to the process of sperm banking and follow-up can be acted upon with minimal implications, others may be more complex.

RESUMO

Writing in plain language makes it easier for patients to read, understand, and make informed decisions about sperm banking. Greater attention to the issue and properly designed educational brochures for use by nurses in oncology and reproductive health is of evident importance but of unknown impact. A multidisciplinary clinical team followed an evidence-based, patient-centered approach to develop "plain language" patient education materials about sperm banking for adolescent and young adult (AYA) males with cancer. A patient education booklet was produced and implemented as part of the planned patient education for AYA male oncology patients at McMaster Children's Hospital, Hamilton Health Sciences, in Hamilton, Ontario, Canada. The patient education booklet for use by health professionals as a teaching tool to facilitate discussion with AYA males has been produced with the hope that it will contribute to better informed decision making regarding sperm banking and increased use of this technology for fertility preservation.

RESUMO

BACKGROUND: Infertility is often a complication for adolescent and young adult males who receive cancer therapy, a problem that might be averted through using cryopreserved sperm. We aim to evaluate feasibility of offering newly diagnosed patients the opportunity to bank sperm and, to determine the beliefs and decision-making processes of patients and their parents who considered sperm banking. PROCEDURE: Eligible patients and parents were approached and offered sperm cryopreservation. Semen samples from patients who sequentially attempted sperm banking were analyzed. Questionnaires were then administered to patients and parents who had been approached about sperm banking. RESULTS: Semen samples from 68 patients were analyzed. Nine patients were azoospermic; all had been pre-treated with chemotherapy. Fifty patients completed the questionnaire. Parent and patient made the decision together to bank 80% of the time. All sons who attempted to bank and their parents felt they had made the right decision, including those who attempted but failed. CONCLUSIONS: Viable sperm can be collected successfully from adolescent and young adults who are newly diagnosed with cancer. Semen quality was dramatically reduced by one course of gonadotoxic therapy. Parents and patients want information regarding sperm cryopreservation early. Parents appear to play an important role in the decision to sperm bank. We recommend sperm banking be offered to all eligible patients.

RESUMO

In order to improve the genetic management of bird species within the European Endangered Programs (EEP), a research project on artificial insemination and cryopreservation of Galliformes semen has been developed. The aim of the program is to create a sperm cryobank for threatened bird species. During this study, semen was collected from 17 pheasant species and specific characteristics of ejaculates were analyzed (volume, sperm concentration, motility, pH). Artificial insemination with fresh semen was performed in nine species and with frozen semen in eight species. Inseminations with frozen and thawed semen were made in 17 species. Viability of fresh and frozen semen was assessed in vitro using double stains, eosin and nigrosin. The effect of pH (7-8.5) on viability of fresh and frozen/thawed spermatozoa was also studied. Chicks hatched in eight and three species after insemination with fresh and frozen/thawed semen, respectively. Species varied widely in semen viability: 1-30% of spermatozoa survived freezing and thawing. There was a negative correlation between the viability of frozen spermatozoa and semen pH. In our experimental conditions, the pH of diluents had no effect on semen viability. However, semen with the highest pH had the lowest quality after freezing and thawing. These experiments demonstrated the feasibility of using a very simple and inexpensive method to achieve artificial insemination and cryopreservation of semen in endangered pheasant species.

RESUMO

This paper examines the physiological preferences of Jewish-Israeli donor insemination (DI) recipients regarding the desirable donor. (1) By comparing recipients' own physiognomy with that of a hypothetical donor, we explore some of the social potentials of DI in its emerging democratized form. We examine prevailing notions regarding the 'natural family' and 'family resemblance' and query the relative weight of the natural vs. the consumer model as applied to one's own family through considerations regarding physical appearance. While examining the 'natural family' concept as a limit in the making of actual Israeli families, we consider the meanings of choice in the context of procreative technologies. The study may also provide practitioners with relevant information for donor matching. The paper is based on questionnaires delivered in four sperm banks during the years 1995-1998. It is important to note that the preferences we study are hypothetical, as in Israel no choice is offered and donor matching is performed exclusively by doctors. (2) Three comparisons serve as vehicles for characterizing the gaps between the natural and the consumer model: women's preferences regarding the donor's appearance vs. their male partners' appearance; men's preferences vs. their own features; single women's preferences vs. those of married ones. The paper ends with a discussion of the social implications of democratized DI on family, gender power relations and social hegemony.

RESUMO

The necessity of establishing of monitored donor's genetic bank in Bulgaria is of exceptional necessity at the moment, when health care in our country is in reorganization and is set on a new base. Our studies were directed towards the organization of bank for cryopreservation of spermatozoa taken of: Donor's genetic material for the needs of obstetric and gynaecological laboratories From men that are expected to go through an X-ray or chemical treatment because of tumors or are planned for operation of the testicules. The genetic bank in IBIR is organised accordance with Bulgarian Legislation.

RESUMO

Testis cancer, chemotherapy and radiation can induce temporary or permanent infertility in men. Cryopreservation of spermatozoa seems an absolute prerequisite in such situation for male patients who are old enough to procreate. We propose a national retrospective study carried out in 17 CECOS. This survey demonstrates a regular increase for semen preservation in testis cancer and analyses the modalities of gametes preservation and their possible use. In view of this activity, we propose a discussion of the attitude of the various CECOS and of particular cases involving ethical issues.

RESUMO

A review of published data on cryoconservation of the sperm of wild animals. Progeny of females inseminated with frozen-thawed sperm was obtained in 21 species and subspecies, including 11 from the Red Data Book. Mobility of the spermatozoa after freezing-thawing was estimated in 74 species, including 13 from the Red Data Book. Studies on cryoconservation have recently been carried out predominantly on the Red Data Book species, as well as the species intensely bred in the countries, where several founder individuals were introduced (deer in Australia and New Zealand). Large zoos and some universities in the USA, Canada and Great Britain are the main research centers.

RESUMO

A survey conducted amongst the 40 donor insemination centres in the UK registered by the Royal College of Obstetricians and Gynaecologists (RCOG) showed that most of the clinics had no structured policy for control of common (non-HIV) sexually transmitted diseases within their programmes.
