This is the emotional moment a fertility doctor called his patients to let them know their treatment worked and they were expecting a baby.

Dr Lawrence Werlin, 72, likes to let the new mothers he works with know they're expecting with a personal touch at his clinic.

So when patients Ashley Mcclendon, 27, and Jake, 29, had IVF, he called them to let them know the results of their tests.

The video shows the pair finding out not only are they expecting, but she had very high hormone levels - which can indicate more than one baby.

Hair stylist Ashley is currently 18 weeks pregnant, expecting twin girls on February 14 2022.

Dr Werlin said: "It is the best and most rewarding part of our day.

"The sheer joy in their voices and having the privilege of sharing this moment with them- it is similar to hearing and watching a child open gifts on Christmas Day!

"Patients work so hard, that when they are successful, all of their emotions come to the surface and we have the luxury of sharing that with them."

"Patients exhibit many different reactions when they receive the news.

"They have heard so much negativity that when they receive good news, they are speechless.

"Saying things like; 'I can't believe it!', 'Are you serious?!' or just silence where I have to ask if they're still on the phone.

"The most heart-wrenching response is tears, when we tell them 'you're pregnant!' and they cry.

"By far this is the most emotionally charged response for them and us.

"We are a team - I could not function without the support of our nurses, lab, and front office people.

"We have always announced our IVF pregnancies as a group, over the phone since we started in 1982.

"This is an incredibly physical, emotional, and financially challenging process.

"We want our patients to know that we are here to support and treat them respectfully as individuals."
