infertility

Women concerned about their fertility can use a test to help decide whether they should freeze their eggs now or whether they still have time to have a baby.

Before a couple commit time, money and emotion to the process of in vitro fertilization, they want to know one thing: What are our chances of having a baby?

Success rates vary dramatically by age. In 2013, for example, 40 percent of IVF cycles performed in women who were under the age of 35 resulted in live births, compared with 4.5 percent for women older than 42.

Melissa and her husband started trying to have a baby right after they got married. But nothing was happening. So they went to a fertility clinic and tried round after round of everything the doctors had to offer. Nothing worked.

"They basically told me, 'You know, you have no chance of getting pregnant,' " says Melissa, who asked to be identified only by her first name to protect her privacy.

But Melissa, 30, who lives in Ontario, Canada, didn't give up. She switched clinics and kept trying. She got pregnant once, but that ended in a miscarriage.

In what's being hailed as a huge step in fertility and reproduction science, doctors in Sweden say a woman has given birth to a baby boy less than two years after she received a uterus transplant. The new mother, 36, had been born without a uterus, so another woman, 61, donated her womb several years after she had gone through menopause.

Egg-freezing. Come on, single ladies; you know you want to. In fact, you wish you had already, like, 10 years ago. Admit it.
