The aim of this dissertation thesis is to emphasize the sense of extended cultivation of embryos to the stadium of blastocyst and its influence on success of assisted reproduction and facilitation of pre implantation diagnosis, analysis of cultivation media and derivation of human embryonic stem cells. Author summarizes current literary findings in assisted reproduction and examines the currently used methods. Author also submits his own published experimental works, in which he compares his own results of infertility treatment with usage of extended cultivation to blastocyst with results of other techniques. Furthermore author submits his own published experimental works which are using extended cultivation for pre implantation diagnosis and its improvement. Another experimental works includes possibility of stem cells derivation. Usage of extended cultivation to blastocyst convincingly leads, according to author's own experiments and simultaneously to available literary findings, to higher success of infertility treatment. This is especially significant by middle-aged mothers. Sufficient term of cultivation enables not just selection, but also biopsy and its generic treatment. Long-term cultivation also enables analysis of cultivation media - but these didn't met the expectations for increase of...

Anal incontinence gradually improved during the time (in 76%). Risk factors of developing (worsening) of anal incontinence were antenatal anal incontinence (in two months period) and women weight (or BMI) meassured at 6-9 months after birth.
