Zetová, Eva-Marie ; Šťastná, Anna (advisor) ; Waldaufová, Eva (referee)
Fertility of women aged 35 and over in selected European countries ABSTRACT This bachelor's thesis deals with the issue of fertility postponement in Europe. It focuses on the fertility of woman aged 35 and over of age in the Czech Republic, the Netherlands, Spain and Norway between 2010 and 2020. It describes the postponement of fertility in a historical context, influencing factors, risks associated with women's fertility at the age of 35+, childlessness, and fertility differentiation by age. The method of analysis is fertility demographic analysis from a transversal perspective. The thesis examines fertility trends of women aged 35 and over, as well as the current similarities and differences in the fertility of older women in the studied countries. Data analysis showed that in all studied countries and years, the proportion of the fertility intensity of women aged 35 and over to the total fertility rate is increasing. Keywords: fertility, fertility postponement, late motherhood, demographic analysis
Analysis of reproductive indicators in dairy cow breeding
KOCOUR, Daniel
The aim of the diploma thesis was to evaluate the trends in the development of reproductive indicators in specific dairy farming and to define the possible causes of the identified problems and propose measures to eliminate or resolve them. The literature review deals with the physiology of cow fertility, synchronization of estrus, hormonal or nervous control of the sexual cycle, the effect of internal and external influences on the reproduction of dairy cows, the effect of reproduction on milk yield and the economic connections associated with the reproduction of dairy cows. The analysis was carried out in the herd of Czech spotted cattle ZD Lukavec in the district of Pelhřimov. A total of 120 dairy cows that ended lactation between January 1, 2022 and December 31, 2022 were included in the monitoring. There were 40 dairy cows in the 1st lactation, 40 dairy cows in the 2nd lactation, and 40 dairy cows in the 3rd and 3rd lactations. higher lactation. In order to evaluate the effects on reproductive indicators (interval, insemination index, length of service period and intermediate period), the data set was sorted by age at first calving, parity, calving and insemination season, milk yield at laktation peak, length of the previous calving interval, RBV of sire and inseminated bulls, occurrence of mastitis and other diseases. The best reproductive results were found in dairy cows that calved for the first time between 715 and 790 days of ageThe length of the service period was the shortest among primiparous heifers. However, the order of lactation had no significant effect on the insemination index. Cows calved in the summer months (June 21, 2021 to September 23, 2021) clearly had the worst reproduction indicators. The time of year when the 1st insemination was performed, however, did not significantly affect reproductive indicators. The length of the previous interval significantly influenced only the length of the insemination interval. Cows with the lowest daily milk yield at peak lactation had the shortest service period and intermediate period. But they also had the lowest average lactation rank. The influence of the RPH of the father on the fertility of the daughters was evident only for the length of the previous intermediate period, when the daughters of bulls with the highest RPH (?106) had the shortest intermediate period (386 days). However, reproductive indicators were significantly influenced by the RPH of the inseminated bull for its own fertility.
Umělý výtěr karase obecného
VRBENSKÝ, Jakub
The thesis briefly summarizes the available information in the field of crucian carp biology. The experimental part includes, firstly, monitoring the effect of water temperature during the latency period in reproductive females affects the success of artificial spawning, the survival of eggs to the eyespot stage, the length of the latency interval in hours and in clock degrees, the relative fecundity of reproductive females and the pGSI. In the second part of the experiment, secondly, the effect of the method of unstickness eggs on the survival of eggs to the eyespot stage. To test the effect of temperature during the latency interval, the females (mean weight 329 +- 60 g) were divided into 7 groups (n = 5). The individual groups of reproductive females were placed in separate tanks with average water temperatures of 15.4, 17.2, 18.9, 21, 23.2, 25.2 and 27.2 °C. Females and males were injected with the hormone Ovopel (1 pellet per 1 kg of fish). Before injection and artificial spawning, the reproductive fish were anaesthetized with clove oil (0.03 ml.l-1). The each group of females were artificially spawned, the eggs were seeded with a mixture of sperm from three males, activated with hatchery water and unsticked with cow's milk diluted with water (1:9). Incubation of eggs was carried out in small experimental Zug bottles (0.45 l) at an average temperature of 21 °C. The highest number of ovulated and artificially spawned females was found at temperatures of 21 - 25 °C (80 %). At lower and higher temperatures the success of spawning was lower. A close positive linear dependence of the latency interval length (in hours) on water temperature was found in the monitored range of 15.5 - 27.2 °C (y =-1.5062 x + 50.663; R2 = 0.924). The length of the latency interval at 21 and 23 °C was 18,4 +- 0,9 and 12,4 +- 0,2 h, respectively 387 +- 18 and 289 +- 5 h°. The eggs have a yellow-brown to green-brown colouration, the average weight of one unswollen eggs is 1,10 +- 0,07 mg (corresponding to 911 +- 51 thousand eggs in 1 kg of eggs). In contact with water, the eggs are very sticky. The highest relative working fecundity was achieved at 21 and 23 °C (71,9 +- 10 and 75,9 +- 34 thousand eggs per 1 kg of female). The average survival rate of eggs to the eyespot, originating from artificially spawned females kept during the latency interval at temperatures between 18,9 - 23,2 °C, ranged from 92.9 +- 0.5 to 99.6 +- 2.2 %, and was lower at 17.2 and 27.2 °C (86.2 +- 0.6 respectively 74.2 +- 3 %), differences between groups were statistically significant. In evaluating the effect of unsticking preparations on the survival of eggs to the eyespots, the highest survival was achieved with milk (71.9 +- 7.3 %). Statistically conclusively lower survival was found with tannin (47.4 +- 0.4 %) and acetylcysteine (48.4 +- 8.6 %). The achieved results can be used in artificial spawning of crucian carp as part of rescue breeding.
Midwife and Reproductive Health
KUBIŠOVÁ, Kristýna
The bachelor thesis focuses on reproductive health with the coherence of midwife's work. The thesis is divided into theoretical and practical parts. The theoretical part deals with the definition of reproductive health, the physiology of human reproduction, the menstrual cycle, and the need for sex and reproductive education. Furthermore, the function of the public health service system is explained as well as the prevention as part of primary care in the Czech Republic. The midwife's doing is clarified along with her competence and her meaning in the prevention topic. The factors which influence reproductive health such as age, diet, recreational drug use, stress, etc. Are described in detail. The bachelor thesis also centers on family planning, a healthy conception, and types of contraceptive methods of birth control and some information about infertility is mentioned as well. The practical part aimed to discover upper-secondary and tertiary education students' opinions about reproductive health. Further, two hypotheses were determined, which were formulated as follows. Hypothesis n. 1: The tertiary students perceive the need for reproductive health education from a midwife more than upper-secondary students. Hypothesis n. 2: Women perceive the need for reproductive health education more than men. Qualitative data collection was chosen on which the questionnaire was based. The questionnaire contained 41 questions (31 closed, 8 mid-closed, and 2 open ones). It was spread in online form through Google Forms application. The research aggregate consisted of 210 respondents from upper-secondary education students (3rd and 4th years) and tertiary students from various occupations. The research sample was composed of students between the age of 17 to 27 from numerous regions of the Czech Republic. Fisher exact test was used for data analyses of the formulated hypotesis. The level of significance was stated as follows alpha = 5 % (0.05). H1 was not confirmed. It was proven that interest in reproductive health education is not dependent on students´ education; either upper secondary or tercially education degree. Also, it was not confirmed that the reproductive health education is required to be performed by midwife. H2 was confirmed. Based on the analysis was proven that women require reproductive health education to be performed by midwife more than men. According to 87 % (182) respondents of our survey the reproductive health education should be included in upper-secondary and tertiary education but 5 % (11) of respondents would not include it at all and 8 % (17) was not sure. The survey has shown that the ideal learner should be an externally educated person in reproductive health. This person would suit 78.5 % (124) of respondents, 8.2 % (13) of students would like to have a doctor for education in this topic. However, 6,3 % (9) of students would like to have teacher from their school and only for 5.1 % (9) of students the midwife would be suitable. The rest of the students, 1.9 % (3) would like to have somebody else. The Bachelor thesis and the survey could be used for purpose of educational plans and materials in topic of reproductive health education for students.

Vaňkátová, Eliška
The bachelor's thesis entitled „Evaluation of the reproduction of selected breeds of rabbits“ deals with the reproductive indicators of rabbits. In the literary review, description of the origin, domestication, significance, biological characteristics and reproduction of the domestic rabbit were described. In the practical part of the work were described two selected breeds of rabbits, namely the breeds Vienna Blue and Burgundy. Their reproductive properties were evaluated and then compared with each other. The results showed that the reproductive characteristics do not differ much between the selected breeds.
The effects of ageing on working age populations that developed and developing countries face: study case of Czech republic and the United Mexican States
Aldama Gonzalez, Hector Santiago
Ageing has always been part of human life; for the first time in history elderly people will soon become the largest group in most societies around the world. This research focuses on highlighting the challenges that developed and developing countries face with the aging of the population. The theoretical part is directed to the understanding of the aging of the population as well as its implication among developed and developing countries. The practical part focuses on a comparison of the aging of the population in the Czech Republic and the United Mexican States through an analysis of quantitative data over the performance of the labor force and general population of Czechia and Mexico with indicators obtained from government institutions specialized in the compilation of population censuses of the last 20 years. The emphasis of this work is to focus on understanding the effects that aging has over society. Unless mechanism such as the creation of new public policies, a positive net migration balance and stable fertility rates are taken to solve the effects of the ageing of the population, the aging of the population will reduce the working age population in the Czech Republic and in the United Mexican States.
Effects of hormonal contraceptives on women's health and fertility
HAVLUJOVÁ, Anna
The bachelor thesis Effect of hormonal contraception on women's health and fertility is dealing with women's knowledge about hormonal contraception, about its effects and its risks and at the same time finds out, from where women take information about hormonal contraception most often. Thesis is divided to theoretical and practical part. In theoretical part is described a history of contraception, phase of the hormonal cycle, which is related to the usage of hormonal contraception and different kinds of contraception including description of advantages and disadvantages based on each types. The individual types of non-hormonal and hormonal contraceptions are described here including their benefits and risks based on their usage. At the end of the theoretical part is added a chapter on the education of women about hormonal contraception by midwives. In the practical part is qualitative research, which consisted from 12 interviews. There is described woman's awareness about benefits and risks, which usage of hormonal contraception represents. Research finds out sources, from which women most often derive their information about homornal contraception. The main point of the thesis is to find out woman's awareness about benefits and risks connected with usage of hormonal contraception, which can affect their health, but also can have negative impact on fertility. The results of research pointed out an insufficient awareness about function of hormonal contraception and poor knowledge in the area of using hormonal contraception. Only two women were able to state serious risk of thrombosis occurence. The knowledge about hormonal contraception were basic and disparate. Women don't use all of available sources of informations. They usually rely on informations from their gynecologist and from closest surroundings. Superficial knowledge is enough for most, but they do not deal with them more in depth. It is necessary to focus more on education on this topic in order for women to not look only on the benefits, but to mainly think about risks, which, hormonal contraception represents and may affect their planned pregnancy in the future. It would be appropriate to focus on women education already in the schools and later in gynecologist's office, where they could apply and pass on their knowledge of a midwife.
