Fertilization, pregnancy and embryo implantation rates after ICSI in cases of obstructive and non-obstructive azoospermia.
The aetiology of azoospermia can be grossly divided into obstructive and non-obstructive causes. Although in both cases testicular spermatozoa can be used to treat male fertility, it is not well established whether success rates following intracytoplasmic sperm injection (ICSI) are comparable. Therefore, a retrospective analysis of fertilization, pregnancy and embryo implantation rates was perf...
متن کاملLive birth rates after MESA or TESE in men with obstructive azoospermia: is there a difference?
STUDY QUESTION How do live birth rates compare after intracytoplasmic sperm injection (ICSI) for men with obstructive azoospermia when using sperm derived from testicular sperm extraction (TESE) versus microsurgical epididymal sperm aspiration (MESA)? SUMMARY ANSWER Our study suggests that proximal epididymal sperm (from MESA) result in higher live birth rates as compared with testicular sper...
متن کاملChanges in Implantation and Survival Rates and Embryo Quality After Progesteron
Purpose: Determining the effect of progesterone on the embryo quality (total cell number and diameter of blastocyst), survival and implantation rates of mouse blastocyst with or without ovarian stimulation. Materials and Methods: Female 6-10 weeks old NMRI mice were divided into four groups as follows: (a) Non-stimulated pregnant mice as control (b) Non-stimulated pregnant mice with daily inje...
متن کاملThe effect of female age and ovarian reserve on pregnancy rate in male infertility: treatment of azoospermia with sperm retrieval and intracytoplasmic sperm injection.
Factors other than spermatozoa could be the major determinant of the success of assisted reproduction treatment in cases of male infertility. Our aim was to evaluate the effect of the wife's age and ovarian reserve on assisted reproduction success rates in the most severe type of male infertility, i.e. azoospermia. A total of 249 consecutive couples suffering from male infertility caused by azo...
متن کاملOutcome of Oocyte Vitrification Combined with Microdissection Testicular Sperm Extraction and Aspiration for Assisted Reproduction in Men
BACKGROUND As a safety and efficacy protocol, oocyte vitrification has been widely used in IVF treatment. The aim of this study was to evaluate the outcome of ICSI-ET utilizing vitrified oocytes with sperm obtained from non-obstructive azoospermia (NOA) patients via micro-TESE. MATERIAL AND METHODS A total of 150 NOA patients underwent micro-TESE. Ten patients were unable to ejaculate and refus...
