Before I agreed to and paid for the treatment he showed a very pleasant and caring behavior. This however completely changed after the the payment was made. The treatment ended up practically with no results caused potentially by human error. Me and my partner have no fertility issues and went through the treatment only for preservation purposes. Although he admitted that something may have gone wrong with the process, he refused any meaningful way of accountability. He did not show any care about our devastation and in fact suggested that we pay more for another cycle. Him and his team made us feel like we are as good as our willingness to spend at his fertility center. Also in the beginning stages of consultation there were a lot of pressure on us with regards to purchasing "other services" such as acupuncture and nutritional consultation. It made us feel we were in a shop rather than a medical facility.Because we were affected by male factor infertility, ICSI & PGS testing were recommended. After about a week, Dr..
