Causal association between family health, perceived relationship quality components, and attitudes toward childbearing in Iranian women: A WHO model analysis.

BACKGROUND: Given the unprecedented global decline in fertility as a major demographic development in recent years, the present study was conducted to determine Causal association Between Family Health, Perceived Relationship Quality Components, and Attitudes toward Childbearing in Iranian Women: A WHO Model Analysis METHODS: In 2023, this descriptive study recruited 400 married women presenting to selected comprehensive health centers affiliated to Alborz University of Medical Sciences, Karaj, Iran. The data were collected through multistage stratified cluster sampling and using a socioeconomic status questionnaire (Ghodratnama), the Perceived Relationship Quality Components (PRQC) scale, the family-of-origin scale (FOS), the attitudes toward fertility and childbearing scale (AFCS) and a demographic checklist were analyzed in SPSS 25 and LISREL 8.8. RESULTS: According to the path analysis, family health exerted the most significant and positive causal effect on attitudes to childbearing directly through one path (B = 0.334) and relationship quality (B = 0.698) and duration of married life (B = 0.387) both directly and indirectly. The number of children (B = -0.057), however, exerted the most significant and negative causal effect on attitudes to childbearing through both paths. CONCLUSIONS: The present findings suggested the significant effects of family health and relationship quality on attitudes toward childbearing. It is therefore recommended that these variables be screened in comprehensive health centers, the associated limitations and problems be identified and appropriate training and counseling solutions be provided by health specialists.

Reproductive function and behaviors: an update on the role of neural estrogen receptors alpha and beta.

Infertility is becoming a major public health problem, with increasing frequency due to medical, environmental and societal causes. The increasingly late age of childbearing, growing exposure to endocrine disruptors and other reprotoxic products, and increasing number of medical reproductive dysfunctions (endometriosis, polycystic ovary syndrome, etc.) are among the most common causes. Fertility relies on fine-tuned control of both neuroendocrine function and reproductive behaviors, those are critically regulated by sex steroid hormones. Testosterone and estradiol exert organizational and activational effects throughout life to establish and activate the neural circuits underlying reproductive function. This regulation is mediated through estrogen receptors (ERs) and androgen receptor (AR). Estradiol acts mainly via nuclear estrogen receptors ERα and ERß. The aim of this review is to summarize the genetic studies that have been undertaken to comprehend the specific contribution of ERα and ERß in the neural circuits underlying the regulation of the hypothalamic-pituitary-gonadal axis and the expression of reproductive behaviors, including sexual and parental behavior. Particular emphasis will be placed on the neural role of these receptors and the underlying sex differences.

Reproductive plan of women in Czechia in the context of late reproductive regime and the COVID-19 pandemic.

The article focuses on short-term (up to three years) and long-term (three years and beyond) reproductive intentions of women aged 18-49 living in the Czechia. Reproductive plans are predominantly formulated at the threshold of adulthood and only 11 % of women under 25 are unsure of their reproductive plans. In the short term, childbearing is planned with the greatest intensity at the ages of 25-29 and 30-34 (when 47 and 33 % of women plan to have a child, respectively), while for childless women the intensity of planning peaks slightly later, at the ages of 30-34 and 35-39 (planning rates of 54 and 50 %, respectively). Older women are not giving up their desire to pursue their reproductive plans. Despite the health risks associated with motherhood at an older age, 20 % of childless women aged 40-44 plan to have their first child in the next three years or later. In addition to age and the current number of children, short- and long-term reproductive plans also differ by women's education, with college graduates more likely to plan to have (another) child in the short and long term than women with less education. At the same time, short-term plans are influenced by women's partnership status, and in the case of long-term reproductive plans, the influence of perceptions of the long-term impact of the COVID-19 pandemic was observed.

A crisis in the life course? Pregnancy loss impacts fertility desires and intentions.

BACKGROUND: An unintended spontaneous termination of a pregnancy can be a traumatic experience affecting the subsequent life course, but has received little attention in socio-demographic studies on fertility intentions or behavior. The theoretical background of our study draws on considerations from life course research, the Theory of Planned Behavior and the Traits-Desires-Intentions-Behavior framework. OBJECTIVE: This study investigates whether the experience of pregnancy loss changes the fertility desires and intentions of women in their subsequent life course. METHODS: We use 11 waves of the Panel Analysis of Intimate Relationships and Family Dynamics (pairfam) with 5197 women in total, of which 281 women (5.4%) reported a miscarriage. Data have been collected annually in Germany since 2008. We investigate four dependent variables capturing different indicators of the ideational dimension of fertility: Personal ideal number of children, realistic number of (additional) children, intention to have a(nother) child in the next two years and importance of having a(nother) child. We study the intrapersonal changes in these items among women after a pregnancy loss, applying linear fixed effect regression models. Controls include parity, age, partnership status, pregnancy status and the interaction of pregnancy loss with whether the woman already had children before the pregnancy loss. RESULTS: We found that the importance of having a(nother) child and the intention to have a(nother) child in the next two years increase after a pregnancy loss. These patterns can only partially be explained by control variables. By contrast, an effect on the ideal number of children as well as the realistic number of children could not be found. The patterns varied, however, across age and stage in the life course, most importantly between mothers and childless women. CONCLUSIONS: Our results demonstrate that the effect of pregnancy loss on the subsequent life course varies across the indicators used and by duration after the pregnancy loss. Overall, they suggest that specifically the younger women in our sample might perceive pregnancy loss as a temporary crisis in their transition to motherhood, or to having another child, and as an impetus to reinforce their fertility goals, while for older respondents this might mark the end of their fertility career. Against the backdrop of rising ages at childbirth, future research on fertility and reproductive health care should pay more attention to reproductive complications and how affected women can be supported in coping with them.

Reproductive behaviour and fertilized spawns in cultured Solea senegalensis broodstock co-housed with wild breeders during their juvenile stages.

The reproductive failure of Senegalese sole (Solea senegalensis) cultured males (reared entirely in captivity from egg through to adult) that do not participate in reproductive behaviours to fertilise spawns, results in a problem to achieve reproductive control in captivity. However, cohabitation with wild males has led to an increase in the involvement of cultured males in reproductive behaviour, although their contribution to fertilised spawning is still lower than that of wild breeders. This study aimed to examine the effect of different social conditions, on the reproductive behaviour and spawning success of cultured breeders over three reproductive seasons. Before starting this study, different social learning opportunities were provided to the breeders from the juvenile to the pubertal stages of the individuals. Behaviour and spawning were evaluated in four experimental groups of cultured breeders: two groups (W1 and W2) that prior to this study were reared during the juvenile stage with wild breeders that fertilized spawns, a Culture breeder group (CB) that was previously reared with cultured breeders that spawned unfertile eggs, and a negative control group (CN) that was reared in isolation from adult fish. During the three reproductive seasons, spawning was obtained from all groups. Generally, the first year had the highest egg production and the third year the lowest. However, fertilised eggs were only obtained from W1 in the first year. A total of eight fertilised spawns were collected with a fertilisation rate of 28.02 ± 13.80 % and a hatching rate of 15.04 ± 10.40 %. The mean number of larvae obtained per spawn was 7,683 ± 5,947 and the total number of larvae from all eight spawns was 61,468. The paternity analysis assigned 64.3 % of larvae to a single couple of breeders, while 34.3 % of larvae were not assigned to any single family, but inconclusively to more than three parents. The highest locomotor activity was observed in W1, while no significant differences were observed in the number of movements within W2, CB and CN. In all groups, during the peak of locomotor activity (19h00-20h00), the main reproductive behaviours observed were Rest the Head and Follow, while the Guardian behaviour was low and Coupled behaviour was only observed in W1. Over time, the reproductive behaviours decreased, except for Follow. The social learning opportunities provided by cohabitation with wild fish during juvenile stages prior to spawning in W1, increased activity and fertilised spawning. However, the number of successful spawns was low and over time stopped in association with a decrease in reproductive behaviour. This suggests that other mechanisms of behavioural learning could be involved in reproductive success, such as reproductive dominance, environmental conditions or hormonal interactions that could affect physiological processes in the reproduction of captive breeders.

Women's involvement in decision-making and association with reproductive health behaviors: findings from a cross-sectional survey in Niger.

BACKGROUND: Though women in Niger are largely responsible for the familial health and caretaking, prior research shows limited female autonomy in healthcare decisions. This study extends current understanding of women's participation in decision-making and its influence on reproductive health behaviors. METHODS: Cross-sectional survey with married women (15-49 years, N = 2,672) in Maradi and Zinder Niger assessed women's participation in household decision-making in health and non-health issues. Analyses examined [1] if participation in household decision-making was associated with modern contraceptive use, antenatal care (ANC) attendance, and skilled birth attendance at last delivery and [2] what individual, interpersonal, and community-level factors were associated with women's participation in decision-making. RESULTS: Only 16% of the respondents were involved-either autonomously or jointly with their spouse-in all three types of household decisions: (1) large purchase, (2) visiting family/parents, and (3) decisions about own healthcare. Involvement in decision making was significantly associated with increased odds of current modern contraceptive use [aOR:1.36 (95% CI: 1.06-1.75)] and four or more ANC visits during their recent pregnancy [aOR:1.34 (95% CI: 1.00-1.79)], when adjusting for socio-demographic characteristics. There was no significant association between involvement in decision-making and skilled birth attendance at recent delivery. Odds of involvement in decision-making was significantly associated with increasing age and household wealth status, listening to radio, and involvement in decision-making about their own marriage. CONCLUSION: Women's engagement in decision-making positively influences their reproductive health. Social and behavior change strategies to shift social norms and increase opportunities for women's involvement in household decision making are needed. For example, radio programs can be used to inform specific target groups on how women's decision-making can positively influence reproductive health while also providing specific actions to achieve change. Opportunities exist to enhance women's voice either before women enter marital partnerships or after (for instance, using health and social programming).

"My Mother Persuaded Me to Have More Children", Understanding the Influence of Social Network on Fertility Behavior in Sub-Saharan Africa.

Introduction: Despite the adoption of an antenatal demographic transition model in sub-Saharan Africa, population growth continues to soar in the region. The reasons for population growth are nebulous and should be approached from different perspectives. Inadequate attention has been paid to how social pressures shape reproductive behavior. Thus, this study examines the association between social networks and fertility behavior in sub-Saharan Africa. Methods: This study used a cross-sectional design that employed a qualitative method to conduct 28 in-depth interviews among married women. Data was collected in 2023. Thematic analyses were utilized to interpret the results. Results: Parental pressure, the desire for more children, the desire for male children, values placed on children, norms, and pronatalist culture were associated with high fertility in sub-Saharan Africa. Conclusions: Thus, there is a need for more awareness of family planning and contraceptive use in order to reduce fertility in sub-Saharan Africa.

'Do I want children later in life?' Reproductive intentions of 1700 adolescents.

PURPOSE: In the past decades, a positive attitude towards having children has been reported in young people. The current generation of adolescents is increasingly concerned about environmental cataclysm which may have an impact on their desire for children. The purpose of this study is to depict the current attitudes in Flemish adolescents towards having children. MATERIALS AND METHODS: All secondary schools in Flanders (Belgium) were invited to distribute an anonymous online survey among their pupils in the last two years of secondary education. In total, 1700 adolescents participated and provided quantitative and qualitative data on their reproductive intentions. RESULTS: Most pupils expressed a desire for children (60.2%), 24.7% were undecided and 10.8% were not willing to have children. Significantly more boys than girls would like to have children (67.0% versus 61.7%, p < 0.01). Adolescents who were uncertain about having children or not interested, reported financial reasons and loss of freedom as most important reasons. CONCLUSIONS: While most adolescents would like to have children in the future, one in four adolescents is undecided and one in ten indicates a wish to remain childless; reasons for wanting children are rather personal, reasons for not wanting children are rather pragmatic.

A desire for parenthood is no longer the norm: 60% of Flemish adolescents would like to build a family, but many are considering a future without children.

Women's reproductive choice and (elective) egg freezing: is an extension of the storage limit missing a bigger issue?

Egg freezing can allow women to preserve their eggs to avoid age-related infertility. The UK's recent extension of elective egg freezing storage has been welcomed as a way of enhancing the reproductive choices of young women who wish to delay having children. In this paper, I explore the issue of enhancing women's reproductive choices, questioning whether there is a more significant aspect overlooked in egg freezing. While increasing storage limits expands reproductive choices for some women, focus on this extension alone, I argue, misses a fundamental issue with egg preservation that often remains ignored; the importance of effective information on egg freezing and the effect this has on women's reproductive choices. Ultimately, I highlight the crucial role of balanced information in enhancing women's choices regarding egg freezing and argue that focusing on extending and increasing provision may obscure this real opportunity to empower women and their authentic reproductive choices.

Reproductive Decision Making of Spanish Women Living With HIV: A Constructivist Grounded Theory Study.

ABSTRACT: The process of reproductive decision making among women living with HIV is intricate and multifaceted, influenced by health considerations, societal factors, and personal values. In this study, we employed Charmaz's Constructivist Grounded Theory to understand how Spanish women living with HIV make decisions regarding reproduction. We conducted 26 face-to-face interviews until data saturation was achieved. Findings suggested that social constructs such as femininity and motherhood play a significant role in the reproductive decision-making process for women living with HIV. The women's beliefs about HIV, doubts, marginalizing situations, and health barriers create challenges to making reproductive decisions. These findings provide valuable implications for designing care plans that meet the unique sexual and reproductive health needs of women with HIV. An integrated and comprehensive multidisciplinary counseling approach is necessary to improve the quality of care.

[The choice of a life without children under the influence of societal concerns]. / Le choix d'une vie sans enfant sous l'influence des préoccupations sociétales.

THE CHOICE OF A LIFE WITHOUT CHILDREN UNDER THE INFLUENCE OF SOCIETAL CONCERNS. Previously unpublished data from 2021 provide an update on the motivations of people who choose not to have children, considering a context of strong social pressure to conceive and a declining birth rate in France. Moreover, childlessness is still a minority phenomenon, and still subject to a certain amount of stigmatization It is part of a social context with a growing concern for ecological issues and the difficulties to achieve gender equality. Taking all of this into consideration, people who choose not to have children are in many ways well anchored in current issues.

LE CHOIX D'UNE VIE SANS ENFANT SOUS L'INFLUENCE DES PRÉOCCUPATIONS SOCIÉTALES. Des données inédites datant de 2021 permettent de faire le point sur les motivations des personnes volontairement sans enfant dans un contexte de forte pression sociale à concevoir et de baisse de la natalité en France. En outre, le non-désir d'enfant est toujours un phénomène minoritaire et encore sujet à une certaine forme de stigmatisation. Par ailleurs, il s'inscrit dans un contexte social où la question écologique prend de l'ampleur et où l'égalité femmes-hommes peine toujours à se réaliser. Les personnes volontairement sans enfant sont, en ce sens, bien ancrées dans la société actuelle.

[The social hygienic aspects of reproductive behavior of women aged 40-45 years].

In the context of forecasted decreasing of natality, actuality of studying its causes for organizational decision-making increases. The purpose of the study was to determine factors affecting reproductive behavior of women aged 40-45 years residing in areas with different natality levels in 2020-2021. The cohort, analytical, sociological methods were applied. The results of study demonstrated that in areas with high natality level most of urban women with higher education and high income resides in conditions of dormitory or mortgage flat and working in profile of their specialty. They are characterized by belated marriage that results in postponed child-bearing. The areas with low natality are characterized by dwelling of rural women with secondary or secondary specialized education. They reside in their own homes and work in other occupations than their specialty. The analysis of social status of women of different age groups will permit more selective approach in developing measures of increasing natality in modern conditions.

Development and psychometric evaluation of the questionnaire on the contributing factors of tendency towards voluntary single-childedness and childlessness: a mixed method study.

Couples' tendency towards voluntary single-childedness and childlessness (VSCC) has turned into a major challenge in all societies and led to different problems such as population aging. A key step to VSCC management is to determine its contributing factors through valid and reliable instruments. This exploratory sequential mixed method study (qualitative-quantitative) was conducted in 2020-2021. Phases of qualitative consists of all couples aged 15-49 in Babol, Iran, who were single or childless. Sampling is based on the purpose, and the number of samples is 20 couples. To collect data, face-to-face and semi-structured interviews were conducted with the participants. Sampling continued until data saturation. The data were analyzed by the conventional content analysis method and quantitative phase. Initially, a qualitative study was conducted on twenty couples, and were analyzed through conventional content analysis. Findings were used to develop QFT-VSCC and then, the face, content, and construct validity as well as reliability were assessed. Construct validity was assessed through exploratory and confirmatory factor analyses and reliability was assessed through internal consistency and stability assessments. The results of the qualitative part analysis consist of 140 codes, 30 primary categories, and nine main categories and two themes (individual limitations and social limitations). The primary QFT-VSCC had 78 items. Fifty-eight items were omitted during validity assessment and the remaining twenty-two items were loaded on five factors during factor analysis. These factors were threatened priorities, inappropriate familial context for childbearing, sense of occupational and social insecurity for the child, social modeling of childlessness, and tendency towards change or stability in marital life. The five factors explained 52.56% of the total variance. All model fit indices in confirmatory factor analysis were acceptable and the Cronbach's alpha values of QFT-VSCC and all its factors were more than 0.70. The results of convergent validity analysis revealed that all factors had an AVE value greater than 0.5, and the HTMT index for all factors was less than 0.85. This indicated that discriminant validity had been achieved. QFT-VSCC is a simple valid and reliable instrument for VSCC assessment among both men and women.

Determinants of high-risk fertility behavior among women of reproductive age in Kenya: a multilevel analysis based on 2022 Kenyan demographic and health survey.

BACKGROUND: Women's high-risk fertility behavior (HRFB), which is characterized by narrow birth intervals, high birth order, and younger maternal age at birth, have been scientifically reported to have detrimental effects on the mother and child's health. To date, there has been limited research into the underlying factors contributing to high-risk fertility behavior in Kenya. Thus, the aim of this study is to identify the factors associated with high-risk fertility behavior among women of reproductive age in Kenya. METHOD: The 2022 Kenyan Demography and Health Survey data was used for the current study. This study included 15,483 women of reproductive age. To account for the clustering effects of DHS data and the binary nature of the outcome variable, a multilevel binary logistic regression model was applied. An adjusted odds ratio with a 95% confidence interval was reported to declare the statistical significance. In addition, the model that had the lowest deviance was the one that best fit the data. RESULTS: The overall prevalence of HRFB among Kenyan women were 70.86% (95%CI = 69.96, 71.40). Women with primary, secondary, and higher educational levels, Protestant and Muslim religion followers, women whose husbands/partners had secondary and higher educational levels, a high household wealth index, ever had a terminated pregnancy, and rural residence, all of these factors were found to be strongly associated with high-risk fertility behavior. CONCLUSION: As per the findings of our study, in Kenya a significant proportion of women has experienced HRFB. This is a matter of concern as it poses a significant challenge to the healthcare system. The high prevalence of HRFB indicates that there is an urgent need to take appropriate measures in order to mitigate its impact. The situation calls for a comprehensive and coordinated approach involving all stakeholders to address this issue effectively. It would benefit policymakers to create programs that consider factors like education, wealth, and residence that make women more susceptible to HRFB. Targeting women living in high HRFB-prevalence areas could help address the root causes of the issue. This approach can alleviate negative impacts and ensure effective and sustainable solutions.

Patients' and providers' perspectives on the decision to undergo non-urgent egg freezing: a needs assessment.

BACKGROUND: Previous research has demonstrated that patients have difficulty with the decision to undergo non-urgent egg freezing (EF). This study aimed to investigate the decisional difficulties and possible decisional support mechanisms for patients considering EF, and for their providers. METHODS: This qualitative study involved a needs assessment via individual interviews. Participants included patients considering EF at one academic fertility clinic and providers from across Canada who counsel patients considering EF. 25 participants were included (13 providers and 12 patients). The interview guide was developed according to the Ottawa Decision Support Framework. Interviews were transcribed, and transcripts analyzed for themes and concepts using NVIVO 12. FINDINGS: Multiple factors contributing to decisional difficulty were identified, including: (1) multiple reproductive options available with differing views from patients/providers regarding their importance; (2) a decision typically made under the pressure of reproductive aging; (3) uncertainty surrounding the technology/inadequate outcome data; (4) the financial burden of EF; (5) inherent uncertainty relating to potential decision regret; and (6) differing perceptions between patients/providers regarding the role providers should play in the decision. Additionally, potential sources of decisional support were identified, including provision of basic information before and/or during initial consultation, followed by an opportunity during or after initial consultation for clarifying information and helping with value judgements. Individualized counselling based on patient values, adequate follow-up, psychosocial counselling, and peer support were also emphasized. CONCLUSIONS: More decisional support for women considering EF is needed. Suggestions include a patient decision aid in conjunction with modified healthcare provider counselling, support and follow up.

Factores de riesgo en la edad reproductiva / Risk Factors in the Reproductive Age

Por medio de la presente y motivados por la lectura y análisis del artículo Características clínicas y microbiológicas de la infección de vías urinarias bajas en población ambulatoria,1 quisiéramos llamar la atención sobre un tema que últimamente tiene poca visibilidad en las publicaciones. Se trata de los factores de riesgo presentes en la edad reproductiva y que inciden negativamente en futuros embarazos, lo que se conoce como factores de riesgo preconcepcional. Al revisar lo publicado en los últimos cinco años apenas se aborda directamente el tema, que por demás mantiene vigencia capital cuando de salud materno infantil se trata. En el trabajo que motiva el análisis, se expresa la frecuencia de aparición de las infecciones urinarias bajas en ambos sexos, más frecuentes en mujeres...(AU)

Differences by age group in gender-related attitudes in Oromia, Ethiopia: Findings from a cross-sectional study of women of reproductive age.

Attitudes on gender roles affect decision-making dynamics, resource distribution, and income-generating opportunities. However, little is known about how attitudes on gender roles differ by age group. Cross-sectional data collected from 1,113 households in Oromia, Ethiopia were used to assess differences in gender-related attitudes across female "youth" (ages 15-24), "young adults" (ages 25-34), and "older adults" (ages 35-49). Fifteen survey questions using a Likert scale measured attitudes on sexual and reproductive behaviors, expectations around livelihood activities, and perceived influence in household decision making. Associations between attitudes and age group were assessed using the Chi-squared test. Measures of perceived influence in decision making differed significantly by age group for household decisions about participation in wage employment, and use of revenue generated from wage employment, and crop and livestock production. Response patterns were consistent, with youth least likely to feel they have influence in decision making. The results suggest that policies and programs should continue to support the agency of female youth.

Reproductive behavior of Atlantic halibut (Hippoglossus hippoglossus) interpreted from electronic tags.

Reproductive timing, location, and behavior are important characteristics that determine marine population dynamics, structure, and resilience to threats, including fishing and climate change. It is challenging to evaluate factors driving variability in these reproductive traits in wild fishes because of the difficulty observing individuals in their natural environments. In the present study, we used high-resolution depth, temperature, and acceleration time series recorded by pop-up satellite archival tags to (1) identify and characterize patterns in depth and acceleration that may be indicative of spawning events in large Atlantic halibut (Hippoglossus hippoglossus), and (2) estimate the effects of individual traits (body size and sex) and environmental factors (location and temperature) on spawning time and frequency. Unique rapid rises observed in the winter depth profiles were interpreted as spawning events. The initiation of the first presumed spawning rise was negatively correlated to water temperature experienced during the prespawning season, suggesting that currently increasing water temperature in the Gulf of St. Lawrence may induce phenological change in halibut spawning time. The number of rises of batch-spawning females was unrelated to female body size. The present study demonstrates how electronic tagging can be used for in-depth characterization of timing, location, and behaviors associated with spawning in a large flatfish species. Such information can inform spatiotemporal management and conservation measures aiming to protect species from directed fishing and by-catch during spawning.

Changes in reproductive behavior associated with the perception and individual experiences of the COVID-19 pandemic.

This study evaluates the impacts of the COVID-19 pandemic on the reproductive behavior of men and women during the most restrictive period of the pandemic in Czechia. At the end of this period, data was collected for the Czech GGS COVID Pilot-Follow-up Study (April 2021), which included additional questions on reproductive plans and perceptions of the pandemic related to fertility. The study focuses in detail on the evaluation of the favorability of fertility during this period by considering the impact of the pandemic on the lives of individuals in various life areas. It subsequently attempts to determine to what extent this evaluation and personal experiences of the pandemic affected reproductive behavior (the intended number of children, current attempts to conceive and short-term fertility intentions). In summary, in most cases the respondents considered the most severe period of the pandemic to be unfavorable in terms of childbirth. Women provided an overall negative assessment of the favorability of childbirth in this period, which was reflected in a reduction in the planned number of children, while the men who considered this period favorable declared a higher chance of short-term fertility intentions.

Monogenoidea Communities Differ Between Male Morphotypes of Bluegill Sunfish (Lepomis macrochirus).

PURPOSE: Bluegill sunfish (Lepomis macrochirus) are a North American sport fish that exhibit two different male morphotypes. Alpha-males are large, colorful, territorial, and have significant parental investment, while ß-males are small, drab, and have two reproductive phenotypes, neither of which involves parental investment. Due to the two different reproductive strategies, the level of interaction between congenerics varies, which may impact parasites that are spread via close contact, such as Monogenoidea that infect the gills. Monogeneans are ectoparasites on the gills and skin of fish hosts that may cause significant pathology in high numbers and be an indicator of host behavior and interaction between hosts. METHODS: In this study, 328 L. macrochirus (106 α-males, 92 ß-males, and 130 females) were necropsied from 8 lakes and ponds in northwestern Virginia to identify and enumerate monogenean parasites from the gills. RESULTS: Alpha-males had a significantly greater parasite abundance and species richness compared to ß-males. This may be due to the increased size and surface area of gills in α-males, increased interaction with females during mating, and stationary behavior when guarding nests, which enhanced the chances of α-males contracting the parasites. This also led to significant differences in the monogenean communities infecting the two morphotypes, which were also significantly influenced by the size of the hosts. CONCLUSIONS: It is important in future studies regarding parasitism that behavioral morphotypes within a sex, such as α-male and ß-male L. macrochirus in this study, be treated separately as behavioral and morphometric differences between them can potentially lead to differences in parasitism.
