Science and technology has been the bedrock of human growth and dynamism. Man has over the years distinguished his existence from all other beings by his ability to champion and fashion his existence. Among his tools is biotechnology which actually attenuates the fears of aging and death.Human Reproductive cloning stands out as one of the means through which biotechnology plans to achieve this perfect existence for man. Technological advancements in the field of biotechnology are now in the threshold of human procreation.Human Reproductive cloning is seen as an assisted method of reproduction which creates a newborn that is genetically identical to another human being.Human Reproductive cloning as a technology and as a means of reproduction is not without its pros and cons. In as much as the technology promises to mention but a few, hope for the infertile couples and single parents, as well as the hope of reproduction without passing on hereditary diseases; it at the same time beeps some flashes of worry.

The aim of the thesis is twofold: the first aim is to identify a number of Reproductive logics that are used to construct Swedish regulation of embryo donation for Reproductive use as either ethical or unethical in the governmental ? and medical discussions ? and to examine how these logics are interconnected with notions of gender and parenthood. The second aim is to identify a number of tensions that arise in the application of the governmental ethical logic on the embryo and embryo donation and discuss how these tensions can be solved with a feminist material approach. I argue that the terminology used to distinguish between genetic, biological, social and legal parenthood in my material is insufficient for understanding the value of the embryo outside its pre-human status. I therefore argue for an embryonic feminist bioethics that is attentive to the embryos post-human status, and for a reformulation of the parenthood terminology in line with what I call ?Reproductive ties?..

Introduction: Studies have shown that women are not always satisfied with the effects of contraception and that contraceptive advice is perceived as non-specific. Aim: The purpose of this study was to investigate what contraceptive women have chosen to use in the different phases of their Reproductive lives, and what they felt had influenced their choice. Method: A retrospective cross-sectional comparative study with a quantitative approach. A survey with fixed and multiple-choice options was sent to five hundred 45-year old women. Result: The study shows that various birth controls are different in the normal Reproductive life.

The aim of this thesis is to explain what actions Sweden and the international communities have been taking in terms of sexual and Reproductive health and rights (SRHR) in order to realize the Programme of Action from the International Conference on Population and Development in Cairo 1994. In a theoretical perspective, donor countries and multilateral organizations are seen as interacting actors involved in global development cooperation. Through applying a human rights approach I will show shortages in terms of supplies to contraception, international agreement on the issue of safe abortions and a new era that comes with new rules for aid and development cooperation. In addition, for human rights to be realized there is the feature of accountability. Without accountability, SRHR cannot be fully respected, guaranteed and protected.

The cat is one of our most common pets. Understanding the Reproductive physiology of the queen is important, not only for the knowledge of our domestic cats but also for wild undomesticated feline species, many of which have been reported endangered. Understanding the mechanisms behind the estrous cycle, ovulation and pregnancy is also important for handling the feral cat populations that are a problem in several countries. The purpose of this literature study is to look into the hormonal patterns of the Reproductive physiology of the female cat, with focus on ovulation, pregnancy and pseudo-pregnancy, and from this information determine in which fields more research would be needed. The female cat is seasonally polyestrous in Sweden, meaning that she can have several estrous cycles during the breeding season but goes through a long period of Reproductive dormancy during the darker months of the year. The queen is considered an induced ovulator, with copulation triggering the release of luteinizing hormone (LH) from the pituitary gland needed for ovulation.

Plagionotus detritus is a threatend longhorn beetle that only exists at one site in Sweden. It is saproxylic and depending on recently dead coarse oak wood for its larval development. Trees at Djurgården, Stockholm that have been colonized by Plagionotus detritus has been studied to find out the habitat preferences of the species and to see what affects the density of beetles in a tree. The bark of some trees and wood from the breeding project at Nordens Ark has also been studied to find out what affects the species Reproductive success. The Reproductive success was measured in two ways, the larval mortality and the size of the hatching holes.

Studiens syfte var att undersöka hur socialt arbete riktat till sexarbetare och som bedrevs i samarbete med sexarbetare utformades på organisationen Reproductive Health Uganda, och hur det upplevdes av dem som var involverade. Metoden var kvalitativa semi-strukturerade intervjuer med fem socialarbetare på Reproductive Health Uganda och med sex kvinnor som är eller har varit aktiva sexarbetare. Materialinsamlingen skedde i Kampala, Uganda, våren 2014. De teoretiska perspektiv och begrepp som användes för att analysera empirin var produktiv makt, erkännande och stigma. Vår slutsats var att det sociala arbetet riktat till sexarbetare som bedrevs på RHU tillsammans med Moonlight stars upplevdes som givande av samtliga informanter.

Functioning Reproductive organs are essential for the survival of a species. The Reproductive system is very sensitive to exposure of chemical substances of anthropogenic origin. Humans release great amounts of chemical substances to the environment by our means of life and these substances have been proved to have a negative effect on the Reproductive ability of different vertebral classes. In the polar bear (Ursus maritimus) a declined Reproductive ability as an effect of decreased testosterone levels and decreased testicular size has been connected to the presence of high levels of organohalogenic compounds like PCBs. Although the Swedish brown bear (Ursus arctos) is not as carnivorous as its close relative the polar bear it is still exposed to environmental.

The chow-chow breed is considered to have a low fertility and this report is an in depth study of the Reproductive functions of this breed in Sweden. Only 53 % of the Chow-chow matings results in litters. Previous studies of other breeds in commercial kennels shows mating results around 85-90 %, but this has not been investigated in hobby kennels and most Chow-chows which are bred from in Sweden, are kept as family pets. Contrary to most other breeds, Chow-chows show a seasonal Reproductive pattern and most litters are born in the autumn. The influence of the month of mating on pregnancy rate and litter size was found to be not significant, but can be considered a trend. Thirty-nine females with previous known fertility problems where studied. Some of them had reached puberty extremely early, at an age between 4-5 months, and many of the bitches showed great fluctuations in intervals between oestrus cycles. Some of the females showed abnormalities such as very short oestrus intervals of only 2-3 months, probably without ovulating.

The pig industry suffers economical loss due to stillbirths, piglet mortality and low birth weight. This is due to breeding programs that have resulted in larger litters. It has been suggested that these problems are due to the metabolic state of the sow during gestation and the fact that she might not be able to supply her foetuses with enough nutrients for survival and a high and even birth weight. A lot of research has been done to investigate whether body weight and back fat thickness of the sow has any impact on her Reproductive traits and if there are any special feed components that improve reproduction. Fibers and unsaturated fatty acids have a positive impact on Reproductive traits as long as the sow is fed a sufficient amount of energy and protein during gestation and lactation.

Phytoestrogens are secondary metabolites produced by plants. Among the plants that make phytoestrogens are soya, red clover and some types of grass. The name phytoestrogen is a collective term for compounds such as genistein, daidzein, biochanin A and formononetin. These compounds are similar to oestradiol-17? in their chemical structure.

Environmental chemicals are transported to the Arctic through the air and oceans, once within the Arctic they spread through rivers, lakes and other watercourses. Polar bears and sledge dogs in-gest high concentrations of environmental chemicals since many of the chemicals are fat-soluble and their diet mainly consists of marine mammals. The aim of this study is to describe how environmental chemicals spread in nature, how they reach the polar bears, and finally how they affect the animals reproduction, with Reproductive hormones and genitals in focus. The animals are exposed to a cocktail effect which complicates the assessment of the chemicals impact on the reproduction. Studies show that the genitals can decrease in size or become malformed, sexual maturation can be affected and the Reproductive hormones can be disturbed.

Blood samples from 44 clinically healthy cats were analysed for the presence of antibodies to Chlamydophila felis. As we wanted to investigate if the antibody titre of clinically healthy cats correlates to shedding of chlamydia, conjunctival and vaginal or preputial swabs respectively, were taken and analysed with rtPCR (real-time polymerase chain reaction) for the presence of chlamydia DNA. Furthermore, to investigate possible epidemiological factors connected with asymptomatic cats infected with chlamydia and to see if there were any indications that chlamydiosis can cause Reproductive problems, the owners of the cats were asked questions regarding this. Sixty-one per cent (27 of 44) of the cats were seropositive. Three of these (11 %) had the highest antibody titre (1:1600).

This literature study investigates the natural behaviour of the cat and handling of cats in the clinic. A presentation of tactile, olfactory, visual and acoustic communication is given. The Reproductive behaviour of the cat is explained and the development of kittens is described. The study highlights hunting behaviour, territory structures and social life of cats. The report also includes practical instructions to how the environment and handling of cats in clinics can be improved..

The presence of cystic ovarian follicles represents an important ovarian dysfunction and is a major cause of Reproductive failure in dairy cattle. A cystic ovarian follicle is a persistent follicular-like structure on one or both of the ovaries. It is at least 2,5cm in diameter and it has to persist for at least ten days while a corpus luteum is missing. There are two kinds of cystic ovarian follicles, those who have a progesterone production and those who have not. A clear definition for this condition is lacking, probably because the heterogeneity of the clinical signs and the complexity of the disorder.
