Using Sperm Transcriptome in Search for Novel Biomarkers of Male Infertility
Semyakina, Anastasiya ; Liška, František (advisor) ; Stopka, Pavel (referee)
Currently infertility affects 10 to 15 percent of couples. In nearly 50% of all cases male factor contributes to infertility of the couple. Majority of causes of male infertility remains unexplained. For this reason, finding simple and clinically useful tools for improving male infertility diagnostics can be important at present. Based on the analysis of sperm transcriptome, in this diploma thesis we aimed to find genes that show differential expression between normal and pathological sperm, this could provide information about molecular basis of male infertility, moreover, expression profile of such genes in sperm could be employed for noninvasive diagnosis of male infertility. This study was conducted by using 67 sperm samples, including 16 control sperm samples from fertile men. The samples of infertile patients were divided into 3 groups according to morphology and motility using results of standard sperm evaluation according to WHO. First group included 20 patients diagnosed with astenoteratozoospermia (low sperm motility and abnormal morphology), second group was 15 patients diagnosed with asthenozoospermia (normal morphology and low sperm motility), the third group comprised 16 samples from infertile patients with normal spermiogram. 16 control samples were from fertile men (conception of...

The problem of infertility and the methods of resolving..

4 Abstract This diploma thesis is concerned with modern methods of treatment for infertility. It examines to what extent and in what cases are these methods used and what risk does it pose for a woman's and a child's health. Paticular emphasis is placed on the methods of assisted reproductive technology as the most used, effective and the most invasive. Nowadays 10-15% of couples face the problem of infertility. In most of the cases this problem can be solved with the help of hormonal therapy, surgery or assisted reproductive technology. The most common complication of ART (assisted reproductive technology) is ovarian hyperstimulation syndrome which leads to higher frequency of miscarriages and can be fatal for a woman. Since more that one embryo is usually transferred in ART children conceived with the help of this method can face different problems related to multiple pregnancy such as higher risk of preterm birth, higher risk of congenital disorder or intrauterine growth retardation. Key words: ART, assisted reproductive technology, infertility, congenital disorder, multiple pregnancy
