A Review of Supportive Interventions Targeting Individuals or Couples Undergoing Infertility Treatment: Directions for the Development of Interventions

Deafening Silence of Male Infertility

Think about 6 loved ones of reproductive age in your life. Now imagine that 1 of these 6 individuals is suffering from infertility. Perhaps they feel alone and isolated, unable to discuss their heartbreak with their closest friends, family, and support network. Suffering in silence. In this editorial, we discuss the infertility journey through the lens of the patients, the providers, and the scientists who struggle with infertility each and every day. Our goal is to open a dialogue surrounding infertility, with an emphasis on dismantling the longstanding societal barriers to acknowledging male infertility as a disease. Through education, communication, compassion, and advocacy, together we can all begin to break the deafening silence of male infertility.

Protective Relational Factors of Lesbian Couples Navigating the Fertility Process

Little research about lesbian couples' experiences with fertility treatment exists in the counseling literature. While there is an increase in lesbian couples exploring fertility options to expand their families, it is important to understand their experiences during this stressful process. This research seeks to understand these experiences using Moustakas' Imaginative Variation method with seven lesbian couples. Results include feelings of isolation, psychological and physical stress. Despite myriad difficulties associated with assisted reproductive technology, participants' experiences show the presence of strong relationship factors, divided into three categories: connectedness, mutuality, and resilience. The use of Relational Cultural Theory may be helpful to lesbian couples looking to expand their families through reproductive methods.

Counseling pregnant people after previous termination of pregnancy for fetal anomaly (TOPFA): the double RAINBOW approach

BACKGROUND AND OBJECTIVES

Pregnancy loss is exceptionally common, yet there exist few interventions for clinical providers to assist parents who are expecting again. Perhaps even less prevalent are practice models for parents who have terminated a pregnancy due to fetal anomaly (TOPFA). In this article, we present the "Double Rainbow" acronym, which provides evidence-supported guidance for counseling people experiencing a subsequent pregnancy after TOPFA.

DESIGN AND METHODS

Using prompts of: Remember; Rehearse & Anticipate; Attach & Internalize; Interrogate decision; Neutralize; Normalize; Bond; Breathe & Observe; Optimize health; Weave and Whole story, we tie intervention techniques to evidence-based treatments and clinical practice examples.

RESULTS

Filling a gap for guidance for effective intervention with people during subsequent pregnancies after termination of pregnancy due to fetal anomaly, we aim to improve such treatment while also encouraging evaluation of the approach, encouraging evaluation of its use with broader populations.

CONCLUSIONS

The double RAINBOW approach weaves together evidence-based therapies while also attending to the work of distinguishing past losses and promoting parental attachment and caregiving systems in clients who have terminated a pregnancy due to fetal anomaly.

Proteomic changes in human spermatozoa during in vitro capacitation and acrosome reaction in normozoospermia and asthenozoospermia

BACKGROUND

The cellular and molecular mechanisms of the events that help spermatozoa acquire their fertilizing capability during capacitation and acrosome reaction are not completely understood.

OBJECTIVE

This study was performed with a postulation that the identification of sperm proteins and their changes during in vitro capacitation and acrosome reaction will unravel unknown molecular aspects of fertilization that impact male fertility.

MATERIALS AND METHODS

Spermatozoa collected from sequential conditions, that is, separation of ejaculated spermatozoa by Percoll gradient centrifugation, in vitro capacitation, and acrosome reaction were processed for tandem mass spectrometric analysis, followed by protein identification, label-free quantitation, and statistical analysis.

RESULTS AND DISCUSSION

Collectively, a total of 1088 sperm proteins were identified. In comparison to ejaculated spermatozoa, 44 and 141 proteins were differentially expressed in capacitated and acrosome reacted spermatozoa, respectively. A large number of proteins were found downregulated, including clusterin, pyruvate dehydrogenase E1 component, semenogelin-1 and 2, heat shock protein 90, beta-microseminoprotein, and keratin. It was expected as sperm-membrane-associated proteins are removed during capacitation. There were significant proteomic alterations in asthenozoospermia compared to normozoospermia; however, variation was more noticeable among proteins of acrosome reacted spermatozoa and those released during the acrosome reaction. The processes enriched among downregulated proteins in asthenozoospermia included acrosome assembly, binding of spermatozoa to zona pellucida, nucleosome assembly, flagellated sperm motility, protein folding, oxidative phosphorylation, tricarboxylic acid cycle, chromatin silencing, gluconeogenesis, glycolytic process, and glycolysis.

CONCLUSION

The dynamic information generated about proteomic alterations in spermatozoa during capacitation and acrosome reaction and their variability in asthenozoospermia will contribute not only to enhancing our understanding of processes that prepare spermatozoa to acquire fertilization capability but also help in deciphering novel factors of male infertility.

The needs of subfertile couples continuing to attempt natural conception: in-depth interviews

STUDY QUESTION

What are the experiences and the support and sexual advice needs of subfertile couples continuing to attempt natural conception after the diagnostic fertility work-up?

SUMMARY ANSWER

Exploration of the experiences of couples showed that couples would have appreciated fertility clinic staff embedding expectant management into the fertility clinic trajectory, supportive staff with female and male patient interactions and advice on common experiences of peers and on managing their lifestyle, distress and subfertility-related sexual challenges.

WHAT IS KNOWN ALREADY

Dutch and British professional guidelines advise newly diagnosed subfertile couples with a ‘good prognosis’ to continue to attempt natural conception and do not require fertility clinic staff to interact with patients. Fertility clinic staff and subfertile couples struggle to follow these guidelines as they feel an urgent need for action. Subfertile couples might benefit from sexual advice, as subfertility is negatively associated with sexual functioning, which is important for natural conception.

STUDY DESIGN, SIZE, DURATION

Twelve one-time in-depth interviews (2015–2017) were conducted with 10 heterosexual couples and 2 women whose partners did not participate, then the interviews were subjected to inductive content analysis, reaching inductive thematic saturation.

PARTICIPANTS/MATERIALS, SETTING, METHODS

The 22 interviewees had experienced 3–18 months of expectant management after their diagnostic fertility work-up in a Belgian or a Dutch tertiary fertility clinic. The face-to-face in-depth interviews explored positive and negative experiences and unmet needs. The transcribed interviews were subjected to inductive content analysis, by two researchers discussing initial disagreements.

MAIN RESULTS AND THE ROLE OF CHANCE

Couples would appreciate fertility clinic staff embedding expectant management in the fertility clinic trajectory, by starting off with reassuring couples that their very thorough diagnostic fertility work-up demonstrated their good chance of natural conception, and by involving couples in deciding on the duration of expectant management and by planning the follow-up appointment after expectant management up front. Couples had encountered sexual challenges during expectant management and had an interest in sexual advice, focused on increasing pleasure and partner bonding and preventing the rise of dysfunctions. The couples agreed that a (secured) website with evidence-based, non-patronizing text and mixed media would be an appropriate format for a novel support programme. Couples were keen for interactions with fertility clinic staff which addressed both partners of subfertile couples. Couples also valued advice on managing their lifestyle and distress and would have liked information on the experiences of their peers.

LIMITATIONS, REASONS FOR CAUTION

Recall bias is plausible given the retrospective nature of this study. This explorative interview study was not designed for examining country or gender differences in experiences and needs but it did generate new findings on inter-country differences.

WIDER IMPLICATIONS OF THE FINDINGS

Rather than simply advising expectant management, fertility clinics are encouraged to offer couples who continue to attempt natural conception after their diagnostic fertility work-up, supportive patient–staff interactions with advice on common experiences of peers and on managing their lifestyle, distress and sexual challenges related to subfertility.

Partner perspectives on women's sexual and reproductive healthcare in cystic fibrosis

BACKGROUND

Women with cystic fibrosis (CF) face many sexual and reproductive health (SRH) concerns. Studies suggest that educating and involving partners in SRH care can improve outcomes. This study investigated partners' perceptions of and preferences for women's SRH care in CF.

METHODS

We surveyed partners of women with CF from ten United States (U.S.) CF centers regarding their attitudes and preferences related to CF SRH care. Items assessed experiences with SRH care, sexual relationships, family planning, pregnancy, fertility, and parenthood. We used descriptive statistics to assess results related to the timing, content, setting and delivery of CF SRH care.

RESULTS

A total of 94 partners completed the survey (94% male; average age 36±1 years; 70% married; 36% parents). Among those who/whose partners experienced a pregnancy, 48% received preconception counseling and 29% fertility testing/treatment. One-third of all respondents (32%) worried their children would have CF and 86% would undergo CF genetic testing if their CF partner became pregnant. One-third (34%) indicated that they did not have any SRH conversations with their partner's CF team, while 70% would like to have such discussions. The topics that respondents would most like to discuss were pregnancy (50%), fertility (43%), sexual functioning (36%), sexual activity (31%) and parenthood (29%).

CONCLUSIONS

Partners report gaps in SRH care and counseling despite the majority wanting to discuss SRH concerns with their partner's CF team. CF partners serve as key supports for women with CF and results can be used to design patient-centered interventions to optimize CF SRH care.

Development of Holistic Health Care Interventions for Women With Infertility: A Nominal Group Technique

Infertility care is often directed by a biomedical approach rather than a holistic approach, especially in African countries. This article explores the opinions of health care providers regarding holistic health care interventions in managing women with infertility in Ghana. Data were retrieved using a qualitative design and nominal group technique with a purposive sample of 12 health care providers in Ghana. Data were analyzed through thematic analysis. Health care providers explored various psychological, educational, spiritual, social, and medical interventions to ensure women diagnosed with infertility receive holistic treatment and attain optimal health.

The Relationship Between Infertility, Stress, and Quality of Life with Posttraumatic Stress Disorder in Infertile Women

Background:

The infertility experience and its treatment are accompanied by the symptoms of posttraumatic stress disorder (PTSD). The aim of this study was determining the relationship between posttraumatic stress disorder and quality of life and the infertile women’s stress.

Methods:

In this descriptive-analytic study, 172 infertile women were divided in four groups. Convenience sampling was done and eligible infertile women referred to Qafqaz Infertility Center in Iran were included in the study. The data was collected between January and March 2019 through posttraumatic stress disorder checklist, The Fertility Quality of Life (FertiQoL) questionnaire, and Newton's infertility stress questionnaire. Pearson correlation, linear regression analysis, and two-way analysis of variance (ANOVA) were applied for data analysis with a significance level of 0.05.

Results:

The results of two-way analysis of variance (ANOVA) revealed that there was no significant relationship between the type of treatment (p=0.548) and the reception of psychological intervention (p=0.450). In addition, the results of Pearson correlation showed that there was an inverse significant relationship between the total score of posttraumatic stress disorder and quality of life (r=−0.91, p<0.001) and a direct relationship between the total score of posttraumatic stress disorder and level of stress (r=0.56, p<0.001).

Conclusion:

The results of this study showed that 41.3% of the infertile women had the symptoms of posttraumatic stress disorder. Due to the relationships of posttraumatic stress disorder with the quality of life and infertility stress, providing regular designed psychological interventions is recommended for infertile individuals.

Study on the Interdependent Relationship between the Marital Satisfaction Variable and the Psychosocial Impact of Infertility and Anxiety Disposition, According to Gender

This study assessed the relationship between the marital satisfaction variable and the psychosocial impact of infertility and anxiety disposition, testing for possible gender-based differences. Comparisons performed on 87 couples did reveal differences and analyses disclosed that depression, anxiety and quality of life can influence the assessment each partner makes of their relationship, through an interdependent process. One partner's marital satisfaction can be influenced by those variables in the other partner. These findings indicate that psychosocial care for infertile couples must involve both partners and that they should be made aware of the effect of interdependence on marital satisfaction.

'How did you cope with such concerns?': insights from a monitored online infertility peer support forum

The Research Question posed was 'What coping strategies do fertility patients and trained peer supporters discuss in an online infertility peer support forum?' A thematic analysis was used to examine 244 online posts from a sample of 39 users (37 women and two men) for themes in coping with fertility-related stressors. Data were collected from Connect, a monitored online discussion forum with trained peer supporters. Connect users ranged from 27 to 44 years of age (mean = 34.38) and 33 (84.6%) were nulliparous at the time of the study. A variety of cognitive-reappraisal and practical management coping strategies was discussed across four themes: (i) balancing interpersonal relationships; (ii) partner support; (iii) uncertainty and lack of control; and (iv) positivity and negativity. Experiences of uncertainty and lack of control related to time and schedule, outcomes and waiting for physical symptoms, and the clinic. Connect users commonly discussed the helpfulness of coping strategies. Connect users actively requested experiential information about ways of coping from other patients and peer supporters, highlighting the importance of lived experience to those currently in treatment. Findings support conceptualizations of infertility coping as a process that is unique to the infertility treatment context and that may change throughout a patient's treatment. Trained peer supporters may benefit fertility patients by normalizing, reappraising, and providing practical strategies to ameliorate difficult infertility-related challenges.

Infertility After Cancer: How the Need to Be a Parent, Fertility-Related Social Concern, and Acceptance of Illness Influence Quality of Life

BACKGROUND

Adolescents and young adults (AYAs) given a diagnosis of cancer who experience infertility concerns often report having poorer quality of life (QoL). However, the role of infertility-related stressors and illness acceptance on QoL is not clear.

OBJECTIVE

The aim of this study was to describe the impact of psychosocial factors surrounding cancer treatment and infertility on QoL. We hypothesized that need for parenthood and infertility-related social concerns would be directly related to QoL and indirectly related to QoL through acceptance of illness.

METHODS

Cancer patients/survivors (n = 178; 75.3% female) aged 15 to 29 years completed measures of QoL, acceptance of illness, infertility-related social concerns, and need for parenthood. Path analysis was used to test the hypothesized and subsequent models to determine the best fit for predictors of QoL.

RESULTS

The final model explained 28.36% of the variance in QoL. Lower infertility-related social concerns were directly and indirectly related to higher QoL scores. Need for parenthood did not directly relate to QoL, instead relating directly to increased infertility-related social concerns. Higher acceptance of illness (β = .39) and older age (β = .19) were directly related to higher QoL scores. Female patients had higher need for parenthood (β = .17).

CONCLUSIONS

These findings suggest that social concerns and expectations surrounding infertility have a negative impact on AYA cancer survivors' and patients' QoL, which increases as AYAs approach socially normative parenting age.

IMPLICATIONS FOR PRACTICE

Providing survivors with specialist support to manage their infertility-related social concerns and improve their acceptance of illness has the potential to improve their QoL.

Loss of CEP70 function affects acrosome biogenesis and flagella formation during spermiogenesis

The spermatogenesis process is complex and delicate, and any error in a step may cause spermatogenesis arrest and even male infertility. According to our previous transcriptomic data, CEP70 is highly expressed throughout various stages of human spermatogenesis, especially during the meiosis and deformation stages. CEP70 is present in sperm tails and that it exists in centrosomes as revealed by human centrosome proteomics. However, the specific mechanism of this protein in spermatogenesis is still unknown. In this study, we found a heterozygous site of the same mutation on CEP70 through mutation screening of patients with clinical azoospermia. To further verify, we deleted CEP70 in mice and found that it caused abnormal spermatogenesis, leading to male sterility. We found that the knockout of CEP70 did not affect the prophase of meiosis I, but led to male germ-cell apoptosis and abnormal spermiogenesis. By transmission electron microscopy (TEM) and scanning electron microscopy (SEM) analysis, we found that the deletion of CEP70 resulted in the abnormal formation of flagella and acrosomes during spermiogenesis. Tandem mass tag (TMT)-labeled quantitative proteomic analysis revealed that the absence of CEP70 led to a significant decrease in the proteins associated with the formation of the flagella, head, and acrosome of sperm, and the microtubule cytoskeleton. Taken together, our results show that CEP70 is essential for acrosome biogenesis and flagella formation during spermiogenesis.

Quality of life and infertility stress in homologous and heterologous medically assisted reproduction: The role of common and specific psychopathological traits

PURPOSE

This study compared the quality of life/stress between individuals undergoing homologous and heterologous medically assisted reproduction (MAR) and explored the role of psychopathological traits.

DESIGN AND METHODS

Two hundred and twenty-six participants in homologous (52.2%) and heterologous MAR (47.8%) completed Symptom Checklist 90-R, Fertility Problem Inventory, and Fertility Quality of Life.

FINDINGS

The homologous group showed higher depressive/anxious and obsessive-compulsive traits, hostility and interpersonal detachment, and worse quality of life/stress than the heterologous one. In the homologous pathway, those with higher interpersonal detachment showed worse quality of life, in the heterologous one those with greater paranoid traits had greater stress.

PRACTICE IMPLICATIONS

Psychiatric nursing support should focus on interpersonal detachment in homologous and paranoid traits in heterologous MAR.

The Effect of Sexual Counseling Using BETTER Model on Sexual Function of Women with Infertility: A Randomized Controlled Trial

Objective: Infertility can have adverse effects on sexuality of women. This study aims to examine the effect of sexual counseling based on the BETTER Model on the sexual function of Iranian women with infertility. Method: Eighty women with infertility were randomly assigned to either intervention or control groups. Female Sexual Function Index and Enrich Marital Satisfaction Scale were completed by participants at baseline and two months after. Results: All domains of FSFI (except for pain) were significantly increased (p < 0.001) after the intervention. Conclusions: Results showed that two sessions of sexual counseling can be used to improve the sexual health of infertile women.

Effect of an Infertility Counseling Education Program on Education Satisfaction and Counseling Competency of Nurses

The purpose of this study is to investigate the effects of an infertility counseling education program on education satisfaction and counseling competency of nurses. The study used a one-group pretest-posttest design. Participants were 135 nurses in Korea. Data on demographic characteristics on education satisfaction, and counseling competency were collected. After participating in the infertility counseling education program, the level of counseling competency increased significantly over that before participating in the infertility counseling education program. The infertility counseling education program improved the counseling competency of the participating nurses. Use of such an infertility counseling education program is recommended when nurses counsel patients facing infertility. It is necessary to repeat this study in the future to clarify the effects of these counseling education programs.

Development and Application of a Web-based Integrated Support Service Program for Infertile Women

Online-based infertility education provides a health management system to patients using electronic information and technology and no face-to-face interaction with patients and experts. This is a study to develop a web-based integrated support service system to meet the health care and nursing needs of infertile women. To develop a system that is most suitable and practically helpful to infertile women, who are end users of this system, research was conducted. This education system consists of introduction to women's health care, information on women's health, information on organizations for women, community for infertile women, and request for consultation for health management and nursing education of infertile women. This study introduced and applied a user-centered design that maximizes the value of use by first understanding the user's convenience and needs when developing a program.

Neurophysiology of cognitive behavioural therapy, deep breathing and progressive muscle relaxation used in conjunction with ART treatments: a narrative review

BACKGROUND

Infertility is defined as the failure to achieve clinical pregnancy after 12 months of regular unprotected intercourse. It could be due to male or female factors, each requiring different treatment options. ART treatment exposes couples to numerous psychological stressors. Therefore, it has been recommended by the ESHRE Psychology and Counselling Guideline Development Group recently that psychosocial support should be offered as a complementary therapy during infertility treatments. In this context, the efficiency of different psychological interventions, such as cognitive behaviour therapy (CBT), deep breathing (DB), and progressive muscle relaxation (PMR), was evaluated in several clinical trials in terms of couples' mental health and pregnancy outcomes.

OBJECTIVE AND RATIONALE

The neurophysiology of CBT, DB and PMR, which are used in interventional studies, in both men and women undergoing ART, has not yet been fully elucidated. This review represents a comprehensive report, aiming to collate novel insights into the neurobiological processes and physiological mechanisms that occur during the practice of CBT, DB and PMR.

SEARCH METHODS

PubMed, Google Scholar and Cochrane Library were interrogated to conduct this comprehensive literature review. The search was carried out using combinations of MeSH terms and keywords: infertility, assisted reproductive techniques, IVF, ICSI, emotions, psychological stress, cognitive behavioural therapy, mind-body therapies and relaxation. Relevant information related to the mechanism of action of stress management techniques were obtained from original articles and reviews published in English without taking into consideration the time of publication. Moreover, as it was not the major focus of the review, only recent systematic reviews (2015-2019) pinpointing the effects of psychological interventions on infertility treatment outcomes were also retrieved from the above-mentioned databases.

OUTCOMES

CBT, DB and PMR may modify the activity of stress-related brain regions such as the prefrontal cortex, amygdala, hypothalamus and hippocampus, as demonstrated by functional MRI and electroencephalogram studies. Furthermore, applying these techniques was associated with mood improvements and a decline in stress biomarkers, and, hypothetically, reducing stress biomarkers attenuates the stress-induced effects on ART outcomes.

WIDER IMPLICATIONS

Increasing the knowledge of fertility staff, researchers and physicians regarding the mechanisms of action of these stress management techniques has several advantages. For instance, understanding the underlying neurophysiological pathways would assist practitioners to engage ART couples in the practice of these techniques. Also, it may enhance the quality of the support programmes and psychological research. Accordingly, this will ensure that these interventions reach their full potential and therefore improve clinical outcomes.

The impact of cancer-related fertility concerns on current and future couple relationships: People with cancer and partner perspectives

OBJECTIVE

The purpose of this study was to examine how cancer-related fertility concerns impact on couple relationships from the perspectives of people with cancer (PWC) and partners of people with cancer.

METHODS

A qualitative research design was used, drawing data from open-ended responses to a survey and in-depth individual interviews. Eight hundred and seventy-eight PWC (693 women, 185 men) and 144 partners (82 women, 62 men), across a range of tumour types and age groups, completed a survey, and 78 PWC (61 women and 17 men) and 26 partners (13 women and 13 men), participated in semi-structured interviews.

RESULTS

Thematic analysis identified that many PWC and partners experience a 'double burden', manifested by cancer-related fertility concerns creating relational stress, changes to couple sexual intimacy and feelings of inadequacy when forming new relationships. However, many participants adopted strategies to facilitate coping with infertility or fertility concerns. This included acceptance of infertility and privileging of survival, focusing on relationship growth, optimism and nurturing in other ways.

CONCLUSION

Cancer-related fertility concerns can have a significant impact on couple relationships. Psychological support from clinicians may facilitate couple coping, as well as help to address concerns about future relationships for un-partnered people with cancer.

Psychometric properties of the FertiQoL questionnaire in Italian infertile women in different stages of treatment

BACKGROUND

Reliable Fertility-specific QoL measures can be obtained through the FertiQoL, a questionnaire with six-subscales that consider different core aspects of the person's wellbeing and way of behaving during treatment.

OBJECTIVE

Examine the psychometric properties of all six-subscales of the Italian FertiQoL in a sample of infertile women and explore the effects of the ART treatment phases.

METHOD

323 women, in three different treatment stages (Diagnostic, Stimulation, Transfer), completed the FertiQoL. Raw data were subject to Confirmatory Factor Analysis (CFA), and a structural equation modelling (SEM) was used to validate the hypothesised model.

RESULTS

CFA shows a good fit of the data to the FertiQoL hierarchical model (chi-square/df = 1.989, CFI = 0.88, RMSEA = 0.055). After the deletion of 2 items, all FertiQoL scales have good internal consistency. SEM showed that the ART treatment phase was positively associated with fertility-related QoL scores both in the Relational (β = 0.14, p < 0.05) and in the Tolerability (β = 0.17, p < 0.05) subscales.

CONCLUSION

All scales of the Italian FertiQoL version maintain good psychometric characteristics; Tolerability and Relational subscales are sensitive to the treatment stage and thus providing relevant information for the medical staff.

Testing a New Group Intervention for Couples Seeking Fertility Treatment: Acceptability and Proof of Concept

This study tested the acceptability and preliminary efficacy of a novel group intervention for couples seeking fertility treatment. Twenty-nine couples completed psychological, relational, and sexual outcome measures pre- and post-intervention. Repeated-measures ANOVAs revealed significant reductions in terms of depressive symptoms, rejection of childfree lifestyle, and stress related to the need for parenthood. The results also revealed improvements in marital benefits and fertility-related emotional and relational quality of life. Couples' high participation rates and reported treatment satisfaction indicate adequate acceptability. These results support the preliminary success of the intervention in reducing the psychological and relational burden for couples undergoing fertility treatment.

Development of Nurses&apos; Practical Educational Needs Scale for Women with Infertility

PURPOSE

To develop nurses' educational needs scale for woman with infertility.

METHODS

A total of 201 nurses in charge of infertility health services in 4 infertility hospitals and 1 public health center were enrolled for this study. The scale was developed through literature review, in-depth interview, development of preliminary items, verification of content validity, development of secondary items, verification of construct validity, and extraction of final items. Data were analyzed using item analysis, exploratory factor analysis, Pearson's correlation coefficients, and Cronbach's α.

RESULTS

Nurses' educational needs scale for women with infertility consisted of 41 items. Three factors (education for disease and symptom of infertility, supporting and counselling for infertility patients, and education for daily life of infertile patients) explained 63.7% of the total variance. CONCLUSIONS: Nurses' educational needs scale for woman with infertility demonstrated acceptable validity and reliability. Its items could be used to assess the level of educational needs for nurses in charge of infertility health services.

Proteomic profile of human spermatozoa in healthy and asthenozoospermic individuals

Asthenozoospermia is considered as a common cause of male infertility and characterized by reduced sperm motility. However, the molecular mechanism that impairs sperm motility remains unknown in most cases. In the present review, we briefly reviewed the proteome of spermatozoa and seminal plasma in asthenozoospermia and considered post-translational modifications in spermatozoa of asthenozoospermia. The reduction of sperm motility in asthenozoospermic patients had been attributed to factors, for instance, energy metabolism dysfunction or structural defects in the sperm-tail protein components and the differential proteins potentially involved in sperm motility such as COX6B, ODF, TUBB2B were described. Comparative proteomic analysis open a window to discover the potential pathogenic mechanisms of asthenozoospermia and the biomarkers with clinical significance.

Zinc levels in seminal plasma and their correlation with male infertility: A systematic review and meta-analysis

Zinc is an essential trace mineral for the normal functioning of the male reproductive system. Current studies have investigated the relationship between seminal plasma zinc and male infertility but have shown inconsistent results. Hence, we systematically searched PubMed, EMBASE, Science Direct/Elsevier, CNKI and the Cochrane Library for studies that examined the relationship between seminal plasma zinc and male infertility, as well as the effects of zinc supplementation on sperm parameters. Twenty studies were identified, including 2,600 cases and 867 controls. Our meta-analysis results indicated that the seminal plasma zinc concentrations from infertile males were significantly lower than those from normal controls (SMD (standard mean differences) [95% CI] −0.64 [−1.01, −0.28]). Zinc supplementation was found to significantly increase the semen volume, sperm motility and the percentage of normal sperm morphology (SMD [95% CI]: −0.99 [−1.60, −0.38], −1.82 [−2.63, −1.01], and −0.75 [−1.37, −0.14], respectively). The present study showed that the zinc level in the seminal plasma of infertile males was significantly lower than that of normal males. Zinc supplementation could significantly increase the sperm quality of infertile males. However, further studies are needed to better elucidate the correlation between seminal plasma zinc and male infertility.
