Fertility awareness and parenting attitudes among American male and female undergraduate university students

Brennan D. Peterson; Laura Tucker; Claudia Lampic

BACKGROUND In the USA, the postponement of childbearing reflects contemporary social norms of delaying marriage, pursing educational goals and securing economic stability prior to attempting conception. Although university students are more likely to delay childbearing, it is unclear to what extent they are aware of age-related fertility decline. The current study is the first of its kind to assess fertility awareness and parenting attitudes of American undergraduate university students. METHODS Two-hundred forty-six randomly selected undergraduate university students (138 females and 108 males) completed an online self-report survey adapted from the Swedish Fertility Awareness Questionnaire. Students were evenly distributed between the freshman, sophomore, junior and senior classes with a mean age of 20.4 years. RESULTS Participants wanted to have their first and last child within the window of a womans fertility. However, participants demonstrated a lack of fertility awareness by vastly overestimating the age at which women experience declines in fertility, the likelihood of pregnancy following unprotected intercourse and the chances that IVF treatments would be successful in the case of infertility. Nearly 9 in 10 participants want to have children in the future and viewed parenthood as a highly important aspect of their future lives. CONCLUSIONS Delaying childbearing based on incorrect perceptions of female fertility could lead to involuntary childlessness. Education regarding fertility issues is necessary to help men and women make informed reproductive decisions that are based on accurate information rather than incorrect perceptions.

BACKGROUND Because there is a lack of longitudinal research examining the impact of partner coping in couples experiencing infertility, we know very little about the long-term nature of coping with infertility and how partner coping strategies impact personal, marital and social distress. METHODS Participants were Danish men and women about to start a cycle of assisted reproduction treatment who were followed for a 5 year period of unsuccessful treatments. Multilevel modeling using the actor-partner interdependence model was used to examine the couple as the unit of analysis. RESULTS Active and passive avoidance coping strategies were significantly related to increased personal, marital and social distress at the individual and partner level. Meaning-based coping strategies were related to decreases in a womans individual distress and her partners marital distress. CONCLUSIONS Partner coping strategies have a significant impact on the other member of the couple over time in men and women undergoing infertility treatments over a 5 year period. Physicians and mental health professionals can educate men and women regarding the ineffectiveness of avoidance coping strategies as well as the beneficial nature of finding new meaning and life goals while experiencing the stress of infertility.

Direct and indirect effects of perceived social support on women's infertility-related stress

Mariana V. Martins; Brennan D. Peterson; Vasco Almeida; Maria Emília Costa

BACKGROUND Social support can be a critical component of how a woman adjusts to infertility, yet few studies have investigated its impact on infertility-related coping and stress. We examined relationships between social support contexts and infertility stress domains, and tested if they were mediated by infertility-related coping strategies in a sample of infertile women. METHODS The Multidimensional Scale of Perceived Social Support, the Copenhagen Multi-centre Psychosocial Infertility coping scales and the Fertility Problem Inventory were completed by 252 women seeking treatment. Structural equation modeling analysis was used to test the hypothesized multiple mediation model. RESULTS The final model revealed negative effects from perceived partner support to relationship concern (β = -0.47), sexual concern (β = -0.20) and rejection of childfree lifestyle through meaning-based coping (β = -0.04). Perceived friend support had a negative effect on social concern through active-confronting coping (β = -0.04). Finally, besides a direct negative association with social concern (β = -0.30), perceived family support was indirectly and negatively related with all infertility stress domains (β from -0.04 to -0.13) through a positive effect of active-avoidance coping. The model explained between 12 and 66% of the variance of outcomes. CONCLUSIONS Despite being limited by a convenience sampling and cross-sectional design, results highlight the importance of social support contexts in helping women deal with infertility treatment. Health professionals should explore the quality of social networks and encourage seeking positive support from family and partners. Findings suggest it might prove useful for counselors to use coping skills training interventions, by retraining active-avoidance coping into meaning-based and active-confronting strategies.

Brennan D. Peterson; Jessica M. Block; Lone Schmidt

OBJECTIVE To assess the relationship between infertility, marital benefit, and coping in a sample of men and women undergoing unsuccessful fertility treatments. DESIGN Prospective longitudinal cohort design using multilevel modeling. SETTING Danish public and private hospitals (n = 5) specializing in treating fertility patients. PATIENT(S) Participants were Danish men and women about to start a cycle of medically assisted reproduction treatment who were followed for a 5-year period of unsuccessful treatments. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) The Copenhagen Multicenter Psychosocial Infertility research program Coping Strategy Scales and Marital Benefit Measure. RESULT(S) Compared with men, a greater percentage of women reported high levels of marital benefit. For active-avoidance coping, there was a significant partner effect by gender interaction. Meaning-based strategies increased between 1 and 5 years for men and women. The use of meaning-based coping had a significant positive actor effect with marital benefit for both men and women. CONCLUSION(S) Approximately one-third of participants undergoing unsuccessful fertility treatments reported high marital benefit as a positive consequence of the infertility experience. Partner effects for men and women related to active-avoidance coping may be related to the degree of emotional support that each spouse can offer the other, whereas differences in meaning-based coping indicate a possible timing effect related to gender.

Are severe depressive symptoms associated with infertility-related distress in individuals and their partners?

Brennan D. Peterson; Camilla S. Sejbaek; Lone Schmidt

STUDY QUESTION Are severe depressive symptoms in women and men associated with individual and dyadic infertility-related stress in couples undergoing infertility treatment? SUMMARY ANSWER Severe depressive symptoms were significantly associated with increased infertility-related distress at both the individual and partner level. WHAT IS KNOWN ALREADY?: An infertility diagnosis, the stress of medical treatments and a prior history of depression are risk factors for future depression in those undergoing fertility treatments. Studies examining the impact of severe depressive symptoms on infertility-related distress in couples are lacking. STUDY DESIGN, SIZE, DURATION This cross-sectional study included 1406 couples who were consecutively referred patients undergoing fertility treatments in Denmark in the year 2000. A total of 1049 men and 1131 women were included in the study. PARTICIPANTS/MATERIALS, SETTING, METHODS Participants were consecutively referred patients undergoing a cycle of medically assisted reproduction treatment at five Danish public and private clinics specializing in treating fertility patients. Severe depressive symptoms were measured by the Mental Health Inventory 5 from the Short Form Health Survey 36. Infertility distress was measured by the COMPI Fertility Problem Stress Scales. Multilevel modelling using the actor-partner interdependence model was used to study the couple as the unit of analysis. MAIN RESULTS AND THE ROLE OF CHANCE Severe depressive symptoms were reported in 11.6% of women and 4.3% of men, and were significantly associated with increased infertility-related distress at the individual and partner level. There was no significant interaction for gender indicating that men and women did not differ in how severe depressive symptoms were associated with infertility distress. LIMITATIONS, REASON FOR CAUTION Because of the cross-sectional study design, the study findings only show an association between severe depressive symptoms to individual and partner distress at a single point in time; however, nothing is known about causality. WIDER IMPLICATIONS OF THE FINDINGS This study adds to the growing body of literature using the couple as the unit of analysis to study the relationship between depression and infertility distress. Recommendations for medical and mental health professionals that underscore the potential risk factors for depressed men and women who are pursuing infertility treatments are provided. Additional studies using a longitudinal study design to track the impact of depression on distress over the course of the infertility treatment cycle would be valuable for increasing our understanding of the complex relationship that exists between these psychosocial factors. STUDY FUNDING/COMPETING INTERESTS Authors Brennan Peterson and Matthew Pirritano have no financial disclosures for this study. Camilla Sandal Sejbaek and Lone Schmidt have received research grants from the Danish Health Insurance Foundation (J. nr. 2008B105) and Merck Sharp & Dohme.

Intentions and attitudes towards parenthood and fertility awareness among Chinese university students in Hong Kong: a comparison with Western samples

Chy Chan; T. H. Y. Chan; Brennan D. Peterson; Claudia Lampic; Michelle Yi Jun Tam

STUDY QUESTION What are the levels of awareness regarding female fertility and the intentions and attitudes towards parenthood among Chinese university students in Hong Kong compared with their counterparts in the West? SUMMARY ANSWER Chinese university students in Hong Kong were similarly over-optimistic about the age-related fertility decline, although they were less inclined to have children and undergo fertility treatment compared with their Western counterparts. WHAT IS KNOWN ALREADY Past studies of highly educated young adults in Europe and the USA have found that they are not sufficiently aware of the age-related decline in female fertility, and falsely believe that advanced reproductive treatments such as IVF will overcome fertility problems associated with age. Little is known about the perceptions of Chinese students in Hong Kong, a modernized Chinese city where the fertility rate is among the lowest in the world. STUDY DESIGN, SIZE, DURATION An online cross-sectional survey of Chinese university students in Hong Kong was conducted in 2013. Results were compared with two similar studies in Sweden and the USA. PARTICIPANTS/MATERIALS, SETTING, METHODS A total of 367 university students in Hong Kong (275 female, 92 male; mean age 23) responded to an e-mail invitation to participate in an online survey. Intentions and attitudes towards parenthood and awareness regarding female fertility were assessed using the Swedish Fertility Awareness Questionnaire. MAIN RESULTS AND THE ROLE OF CHANCE Like their Western counterparts, a large proportion of Chinese university students underestimated the age-related fertility decline (92%) and overestimated the fertility treatment success rate (66%). However, they were less inclined to have children, were more aware of and less concerned with infertility and were less motivated to seek solutions in the event of a fertility problem. These comparisons were significant at P < 0.05. LIMITATIONS, REASONS FOR CAUTION Self-selection bias was inevitable in the questionnaire survey, and the anonymous nature of the survey did not permit the collection of characteristics of non-responders. International comparisons warrant caution because the Hong Kong sample was older than the US sample (mean age 20), but not older than the Sweden sample (mean age 24). WIDER IMPLICATION OF FINDINGS While this study was consistent with past Western studies on the lack of fertility awareness among highly educated young people, the findings reveal significant cultural differences in family planning and responses to infertility between Asia and the West.

The Experience and Influence of Infertility: Considerations for Couple Counselors

Brennan D. Peterson; Lisa Gold; Tal Feingold

Infertility, or the inability to conceive or carry a pregnancy to live birth after a year or more of regular sexual relations, affects one in six couples of childbearing age. There is substantial empirical evidence that infertility is related to depression, anxiety, sexual dysfunction, and identity difficulties in both men and women. Given the prevalence of infertility and increases in the number of individuals and couples who seek infertility counseling, it has become imperative that couple counselors understand the distinct and robust set of challenges faced by this population. This article provides a broad background on the state of infertility and elucidates some of the physical, social, and emotional responses to this experience. Gender issues, social norms, and cultural traditions are discussed when examining male and female emotional responses to infertility. In addition, this article presents a framework for appropriate assessment and diagnostic considerations related to the infertility experience.

An introduction to infertility counseling: a guide for mental health and medical professionals.

Brennan D. Peterson; Jacky Boivin; Jan Norré; Cassandra Smith; Petra Thorn; T. Wischmann

The practice of infertility counseling delivered by mental health and medical professionals has become more sophisticated and widespread over the past decade. This paper summarizes information presented at the second campus workshop of the Special Interest Group of Psychology and Counseling of the European Society of Human Reproduction and Embryology (ESHRE). This group is dedicated to improving infertility services by creating meaningful connections between mental health and medical professionals. The paper identifies key issues that infertility counselors must consider in their work with couples experiencing infertility. The use of supportive psychosocial interventions and treatments are highlighted. The paper also details the process for choosing the most appropriate type of infertility counseling, and the use of assessment tools that assist in understanding infertility related symptoms. Infertility counselors should also consider gender differences, the impact of infertility on a couple’s sexual relationship, and the unique challenges couples face regarding third-party conception. Finally, the paper addresses specific recommendations for infertility counselors in mental health and medical settings.

Knowledge, attitudes, and intentions toward fertility awareness and oocyte cryopreservation among obstetrics and gynecology resident physicians

L. Yu; Brennan D. Peterson; Marcia C. Inhorn; Julia K. Boehm; Pasquale Patrizio

STUDY QUESTION What knowledge, attitudes and intentions do US obstetrics and gynecology (OB/GYN) residents have toward discussing age-related fertility decline and oocyte cryopreservation with their patients? SUMMARY ANSWER Most OB/GYN residents believe that age-related fertility decline, but not oocyte cryopreservation, should be discussed during well-woman annual exams; furthermore, nearly half of residents overestimated the age at which female fertility markedly declines. WHAT IS KNOWN ALREADY Oocyte cryopreservation can be utilized to preserve fertility potential. Currently, no studies of US OB/GYN residents exist that question their knowledge, attitudes, and intentions toward discussing age-related fertility decline and oocyte cryopreservation with patients. STUDY DESIGN, SIZE, DURATION A cross-sectional online survey was conducted during the fall of 2014 among residents in American Council for Graduate (ACOG) Medical Education-approved OB/GYN residency programs. Program directors were emailed via the ACOG Council on Resident Education in Obstetrics and Gynecology server listing and asked to solicit resident participation. PARTICIPANTS/MATERIALS, SETTING, METHODS Participants included 238 residents evenly distributed between post-graduate years 1-4 with varied post-residency plans; 90% of residents were women and 75% were 26-30 years old. The survey was divided into three sections: demographics, fertility awareness, and attitudes toward discussing fertility preservation options with patients. Descriptive and inferential statistics were conducted. MAIN RESULTS AND THE ROLE OF CHANCE A strong majority of residents (83%) believed an OB/GYN should initiate discussions about age-related fertility decline with patients (mean patient age 31.8), and 73% percent believed these discussions should be part of an annual exam. One third of residents overestimated the age at which there is a slight decline in female fertility, while nearly half of residents overestimated the age at which female fertility markedly declines. Over three-quarters of residents (78.4%) also overestimated the likelihood of success using assisted reproductive treatments (ARTs). Residents were likely to support oocyte cryopreservation in cancer patients irrespective of the womans age, but much less likely to support elective oocyte cryopreservation. For elective oocyte cryopreservation, 40% believed OB/GYNs should initiate discussions with patients (mean age 31.1), while only 20% believed this topic should be part of an annual exam. LIMITATIONS, REASONS FOR CAUTION Because the study invitation was sent through US OB/GYN residency program directors rather than directly to residents, it is possible that some residents did not receive the invitation to participate. This limits the generalizability of the findings. WIDER IMPLICATIONS OF THE FINDINGS Within the USA, there appears to be a critical need for improved education on fertility decline in OB/GYN residency programs. To promote informed reproductive decision-making among patients, efforts should be made to help OB/GYNs provide comprehensive fertility education to all women, while also respecting patient choices. STUDY FUNDING/COMPETING INTERESTS None.

Interactive effects of social support and disclosure on fertility-related stress

Mariana V. Martins; Brennan D. Peterson; Patrício Costa; Maria Emília Costa; Rikke Lund; Lone Schmidt

Individuals perceiving high social support tend to perceive better adjustment to infertility. However, it remains unclear whether this benefit is affected by the actual disclosure of the infertility condition. The present study aimed to examine the role of disclosure of fertility status in moderating the relationship between perceived social support and fertility-related stress. The study population (N = 698) was drawn from a longitudinal cohort design of Danish men and women beginning fertility treatment with a 12-month follow-up. Participants were 698 subjects (364 women and 334 men) who completed self-administered questionnaires measuring perceived social support at T1, and fertility status disclosure and fertility stress at T2. Results indicated that when infertility is not disclosed to at least a close relationship, the beneficial effects of social support on both social and personal stress cease to exist. Also, when participants perceived high social support, higher levels of social and personal stress were associated with keeping infertility a secret within close relationships, but when low social support was perceived, high social and personal stress levels were associated with disclosing infertility to all close relationships. Findings from this study provide evidence that the prospective relationship between social support and fertility-related stress is moderated by the decision of disclosing infertility. Infertility health professionals can help couples in deciding to which contexts they should disclose their infertility by assessing social support.
