The effect of microfluidic sperm separation on the success of IVF therapy
NOVÁKOVÁ, Pavla
More and more couples are coming to assisted reproduction centres to solve conception problems. Despite initial efforts to improve lifestyle and reduce daily stress, problems in conceiving and delivering a healthy baby can be caused by one or a combination of multiple factors, and in such cases infertile couples opt for assisted reproductive treatment. In earlier times, the focus in the field of reproductive medicine was mainly on female fertility. In recent years, assisted reproductive medicine has largely focused on the field of andrology. In this regard, the development of enhanced spermiogram methods and sperm processing techniques has been developed. The current trend in reproductive embryology and andrology methods is to mimic the in vivo environment as much as possible. The aim of this bachelor's thesis was to determine whether the method of microfluidic sperm separation has an effect on sperm quality and whether the use of sperm obtained in this way influences the success of IVF treatment. In order to achieve the objectives of this study, data from 129 couples who underwent treatment in our IVF centre by donated oocytes and at the same time sperm from fresh ejaculate were used. The sperm samples were divided into two groups, namely for processing by gradient centrifugation and separation by microfluidic chip. The sperm were then used for in vitro fertilization using intracytoplasmic sperm injection method. Cycles with donated oocytes were selected to minimize the influence of female factor. The results of this work indicate that sperm processing by microfluidic chip method has a positive impact on the success of IVF treatment.

Health and social aspects of infertility and its treatment
ZAVADILOVÁ, Zuzana
Infertility is the inability to achieve a pregnancy. WHO classify infertility into two groups. Primary infertility is the term used to describe a couple that has never been able to conceive a pregnancy, after at least 1 year of unprotected intercourse. Secondary infertility describes couples who have previously been pregnant at least once, but have not been able to achieve another pregnancy. Causes of infertility include a wide range of physical as well as emotional factors. Approximately 30 - 40% of all infertility is due to a "male" factor such as retrograde ejaculation, impotence hormone deficiency, environmental pollutants, scarring from sexually transmitted disease, or decreased sperm count. A "female" factor -- scarring from sexually transmitted disease or endometriosis, ovulation dysfunction, poor nutrition, hormone imbalance, ovarian cysts, pelvic infection, tumor or transport system abnormality from the cervix through the fallopian tubes -- is responsible for 40 - 50% of infertility in couples. The remaining 10 -30% of infertility cases may be caused by contributing factors from both partners, or no cause can be identified. This dissertation has two main goals. The first goal is to describe how a couple face up to their problems with infertility. The second goal is that this dissertation can be used as a study material for social and medical employees. This dessertation is based on a qualitative research. I used a method CAMI {--} communication through the use of computer. The observational goup were people disccusing at www.neplodnost.cz.
