"We actually would take Jay's sperm, find the very best-looking one and put it into each of Kelli's eggs so that we could take a single sperm, put it in a single egg, to help with fertilization. Ultimately, that's what made the difference for them," Hinckley said.
The couple's first baby boy, Gavin, was born shortly before Thanksgiving 2009.
"It was the best moment of my life," said Kelli Leiner. "It really was. It was surreal. It was so magical."
Dr. Karen Boyle, regional director of male infertility at Shady Grove Reproductive Science Center, gives some advice on how to boost male fertility.
Be healthy. Eat right and exercise. Men with a body mass index of over 25 have a 20 percent higher chance of infertility, and obese men are three times more likely to have lower sperm counts.
Take your vitamins. Eat foods rich in antioxidants such as vitamins A, C, and E. These vitamins are crucial as they repair sperm DNA. Also zinc, folic acid, selenium and amino acid are good for sperm health.
Try intercourse every other day while trying to conceive. More isn't better. In fact, having sex every day or multiple times a day will lower sperm counts significantly. To maximize fertility potential, every other day is ideal as it allows sperm counts to normalize.
Don't use testosterone or anabolic steroids. That shuts down the signal from the brain to stimulate sperm production and will make sperm counts significantly lower if not disappear altogether.
Don't smoke or use recreational drugs. Smoking impairs sperm motility and morphology and worsens the quality of a man's erections. Marijuana can cause DNA damage and lower sperm counts.
Stay out of hot tubs or Jacuzzis and don't leave a laptop computer on your lap for long periods of time. Prolonged or repetitive heat exposure can adversely affect sperm production.
