Hi,
We used 'Assisted Reproductive Technology Unit, The Chinese University of Hong Kong' at The Prince of Wales Hospital, Shatin.
Professor Christopher Haines and Dr Grace Wong.
We also had male factor infertility, we had the sperm tested over 3yrs while we tried to conceive naturally. After we saw mild improvement (12mnths no alcohol, daily Macca herb supplement from Aus) so we froze some sperm until we were ready for IVF.
We started IVF process in Dec 2012, we were blessed and lucky to have success after the 3rd frozen embryo transfer (now pregnant and due in April 2014). For fertilisation they used fresh sperm as it was better quality than the frozen (back up) 9 out of 13 eggs fertilized (they injected sperm directly into each egg). We have already used 4 and have 5 more frozen on standby.
We highly recommend the private IVF at Prince of Wales, Shatin.
If you want the contact details, let me know.
Good luck to you and always remember hope, strength and courage. Don't give up!
