Transfer of fertilized ova in the hamster

Reamer, Gail R. January 1960 (has links)
Thesis (M.A.)--Boston University / Transfer of fertilized ova from a donor female to a uterine foster mother can be a valuable tool for attack of problems of gen etics, cancer, embryologJ, growth, immunology, and fertilization. The technique has been practiced in the rabbit, mouse, rat, and sheep with varying degrees of success. Holding media for the ova usually consist of blood serum, alone, or modified with a balanced saline solution. Diffusion chambers constructed of Millinore Filter membrane have proved valuable for 'in vivo' and 'in vitro' tissue culture and transnlantation. These chambers serve the useful function of mechanically isolating the contents from surrounding tissues and free cells, while providing diffusion of metabolites and oxygen into the chamber to nourish the enclosed tissue . Experimental procedure Donor albino females were mated with albino males. Approximately 24-33 hours after fertilization, when the ova were in the two cell stage, salpingectomies were performed. The ova were removed from the uterine tubes, and transferred to the ovarian bursa of pseudopregnant albino recipients [TRUNCATED]

KNOWLEDGE, INTENTIONS, AND BELIEFS ABOUT FERTILITY AND ASSISTED REPRODUCTIVE TECHNOLOGY AMONG ILLINOIS COLLEGE STUDENTS

Morris, Akilah 01 August 2018 (has links) (PDF)
AN ABSTRACT OF THE DISSERTATION OF AKILAH MORRIS SMITH, for the Doctor of Philosophy degree in Public Health, presented on April 11th 2018, at Southern Illinois University Carbondale. TITLE: KNOWLEDGE, INTENTIONS, AND BELIEFS ABOUT FERTILITY AND ASSISTED REPRODUCTIVE TECHNOLOGY AMONG ILLINOIS COLLEGE STUDENTS MAJOR PROFESSOR: Roberta Ogletree H.S.D and Juliane P. Wallace PhD The purpose of this quantitative cross sectional study was to examine knowledge, beliefs, and intentions about fertility and assisted reproductive technology among college students. This study differs from previous studies in that it examines knowledge, beliefs, and intentions about fertility and assisted reproductive technology among Illinois college students. Five hundred thirty six undergraduate students from six Illinois universities taking foundational health courses participated in this convenience sample study. Participants included three hundred and five females, 225 males, and five transgender students. The age ranges from 18-60. Five hundred and twenty students were childless. Three hundred and eleven students were single, 195 were in a committed relationship, and 16 were married. An Analysis of Variance (ANOVA) detected the differences among college students’ knowledge, beliefs, and intentions, based on race, sexual orientation, age, parental status, relationship status, and gender. Additionally Multiple Linear Regression analysis determined variations among race, sexual orientation, age, parental status, relationship status, and gender based on intentions, beliefs, and knowledge of fertility and ART treatment options. The first findings indicate that age, race and relationship status variables strongly impacted fertility intentions. The second findings reveal that gender and race impact beliefs influencing fertility and ART treatment options. None of the six variables significantly affected knowledge, which does not correlate with the literature. The students replied that they were not informed about women’s fertility as well as ART treatment options. Caucasians and older students’ intended on delaying parenthood supports the current literatures. According to Martinez, Daniels, and Chandra (2012), Caucasians are more likely to delay parenthood, which this research study supports. Secondly, Caucasians and males students had beliefs that supported the delaying of parenthood. Amongst the six groups, none of the groups affected knowledge. Daniluk and Koert (2012) show that while college student’s lack knowledge researchers are not sure what strongly predict their fertility and ART knowledge treatments.

Essays on Fertility and Fertility Preferences in India

Rajan, Sowmya January 2014 (has links)
<p>In this dissertation, I examine at the aggregate and individual levels, why contemporary fertility preferences diverge from actual fertility. I use three waves of cross-sectional survey data from the National Family Health Surveys from India (also known as the Indian Demographic and Health Surveys), fielded in 1992-3, 1998-9 and 2005-6 to investigate the disjuncture between preferences and behavior. The first empirical chapter outlines and operationalizes a new framework to decompose the incongruence between stated preferences and actual fertility into a set of parameters, such as unwanted births, gender preference and postponement of births to later ages, each of which varies in its level and intensity between societies and over time. By delineating the societal constraints that women do not incorporate in their childbearing intentions, this model provides a useful framework to explain variability in fertility in contemporary intermediate- and low-fertility populations. Equally important, the framework provides avenues to enquire into the fundamental structural and cultural correlates producing differences between family size preferences and actual fertility.</p><p>Subsequent empirical chapters explore various aspects of fertility preferences in detail. The second chapter probes a key socioeconomic correlate of individual-level fertility preferences, namely educational differences in preferences. In brief, I find that educational differences in family size preferences have considerably converged over time using two-way fixed effects models. However, there is still considerable heterogeneity in the implementation of preferences (as manifested by the use of contraception). Accordingly, in the third chapter, I analyze the multilevel sources of variation in the use of contraception by young women, given that they express a preference to space or stop childbearing. Using multilevel models, I find that community norms play a strong role in the use of contraception by young women to meet their fertility preferences to space or stop childbearing. I argue that community norms are an influential determinant of young women's ability to regulate their own fertility - serving to enhance or constrain their use of contraception to either space or stop childbearing. </p><p>Overall, findings from this dissertation highlight the macro-level factors that explain variation in contemporary fertility, of which fertility preferences emerge as a critical parameter. This dissertation also illuminates the growing convergence of fertility preferences across socioeconomic categories, while focusing attention on local community forces that influence fertility behavior even in the face of women's stated preferences.</p> / Dissertation
