Swanni Rivera tried to get pregnant for years. When nothing worked, she turned to In Vitro Fertilization, and now she will celebrate Mother's Day with her 4-month-old twins.

“It was a difficult journey. I caused me a lot of tears, a lot of pain,” Swanni Rivera said.

In America, 12 percent of couples face fertility problems. Like many others, the Riveras went for help to get pregnant. After a surgery and 3 IVF cycles, the twins were conceived. 

Little Isaac’s cries drown out his mother as she talks, while his sister Isis sits in her father’s lap.

“I can’t say how much I’m grateful for this little gift,” she said, as she kissed her baby.

The twins were born on Jan. 7.

Maria Bustillo, a doctor at the South Florida Institute for Reproductive Medicine, where the Riveras went for help, said the solution for infertility depends on the problem.

“If you get 100 couples with infertility about 40 per cent are from a female problem,  40 per cent from a male problem and 20 per cent from a combined problem,” Bustillo said.

IVF was the option for the Riveras because Swanni, 37, suffers from severe endometriosis and has a fallopian tube block.

Success rates depend on many factors but most importantly the age of the woman, Bustillo said.

“If you’re talking about a 40- to 42-year-old, the pregnancy rate is very low,” she said. “If you’re talking about a 30-year-old who is otherwise normal but has bad fallopian tubes, then we’re talking more like 55 to 60 per cent.” 

Jesus Rivera says becoming a mom to twins was the best gift his wife could get. 

They will celebrate again next weekend when the South Florida Institute for Reproductive Medicine holds a reunion part for 400 families.
