As we continue to celebrate International Women's Month this March, Dr. Sonia Gayete-Lafuente talks about a powerful and often overlooked aspect of motherhood: lactation without pregnancy. 

For many women and families, the ability to breastfeed represents far more than nutrition. It’s about bonding, connection, and participation in a deeply meaningful part of early parenthood. The good news? Even if you didn’t carry the pregnancy, breastfeeding may still be possible.

It has been more than 40 years since the first IVF baby was born and today, millions of babies are born using assisted reproductive technology. Throughout the years, new studies and research have been conducted which contributes to the advancement of reproductive medicine. One topic that has become popular is the process of how follicle development is monitored and how to determine the timing of the egg retrieval. 

HIER is based on the understanding that follicle maturity is a biological process, not just a measurement. Instead of treating all patients with the same protocol, the process of HIER tailors the timing of the ovulation trigger and egg retrieval to the individual patient.
