He graduated and received his medical degree from Medical School at the University of Warsaw in 1985 and his residency training in obstetrics and gynecology at Solec University Hospital in Warsaw.
He completed the reproductive endocrinology and infertility fellowship at The Genetic Department of Children’s Memorial Health Institute in Warsaw – Poland as a member of the IVF team in 1992.
One of the most important achievements of his team/ led by Prof. Wisniewski / was the second baby birth through IVF technique in Poland.In 1989, he obtained his PhD in the University of Warsaw, with his dissertation titled “Evaluation of maturity of oocytes after stimulation through IVF method.”
His dissertation includes studies of multiple medication protocols in order to induce ovulation, regarding the morphological maturity in human oocytes after collection. As a reproductive gynaecologist, he finds this experience in embryology to be a very crucial in the process of improving patients care.
During these pioneering years, Dr. Najdecki was deeply involved in research for a “new method” for oocyte pick up. After many years of laparoscopic OPU, he successfully introduced the first vaginal, ultrasound guided oocyte pick up, which resulted in second IVF baby being born in the nation.
This first success led the way to a new era in IVF techniques that goes on until today. He has also been active in fertility research, publishing on topics ranging from fibroids, endometriosis to ovulatory dysfunction and ovarian ageing.
