Abstract
Infertility can cause considerable social, emotional and psychological stress. The European Society of Human Reproduction and Embryology (ESHRE) highlighted that the prevalence of infertility is increasing across the developed world. The main reasons for this is the trend for putting off pregnancy until later in life, an increase in obesity, and the higher rate of sexually transmitted infections.
Infertility is defined as a failure to conceive following frequent unprotected sexual intercourse for one or two years. Diagnosis based on failure to conceive after two years is thought to give a better measure of infertility as around half of women who fail to conceive during the first year are likely to do so in the second year. The term “subfertility” may be used to describe any form of reduced fertility that results in a prolonged duration of unwanted lack of conception.
In Vitro Fertilization(IVF), mature oocytes from stimulated ovaries are retrieved transvaginally with sonographic guidance. Sperm and ova are then combined in vitro to prompt fertilization. If successful, viable embryos are transferred transcervically into the endometrial cavity using sonographic guidance.
The aim of our rertrospective statistical study was to analyze and evaluate workup In ElminiaUniversity IVF center.
The mean age of our study group was 30±5.9 years (range 19-46 years) ad the mean of duration of infertility was 8.9±5.4(range 2-26) years. The majority of our cases had primary infertility (78.4%). Male factors accounted for 93% of infertility causes in our study.
In this studywe used long protocol in 84.8% of our patients, we used drug of stimulation lucrine in majority of cases, andthe mean days of stimulation was 12 days with range from 7 to 21 days.
The mean of number of follicles in right side and left side was closely similar 7.3, and range was from 1 to 20 in both sides. The mean endometrial thickness was 9.3±1.9 mm, the mean number of eggs obtained after stimulation was 10. We obtainedsperm from our patients from semen in 68% of patients, and by testicular biopsy in 28% of them.The mean of number of fertilized PN was 4.8±3.7, witha wide range from 1 to 30, and the meanof number of embryo transfer was 3.3±1.4.
In comparison between SET and DET, TETwe found that implantation rate was higher in SET than DET and TET.
Pregnancy test in our study was achievedin only 56 cases (32 %), while the other 115 (67%) cases failed to achieve pregnancy.
