At around week 16, an unborn baby’s aural structures are quite well developed. He or she should be able to detect some noise, though it will be restricted to the inner noises of mom’s body. By week 24, he or she will be able to hear noises outside the womb, and may respond to mom or dads voice.

According to the American College of Obstetricians around 15-25 percent of all pregnancies will end in a miscarriage.

At six months, a baby should recognize when someone says his or her name. By six months, a baby should also be babbling, making sounds like “oh”, “ah” or “eh”, responding to sounds parents make, and making noise when spoken to.

Pregnancy is technically only possible during the five days before ovulation through to the day of ovulation.

A severely underweight woman (with less than 17 percent body fat) may have irregular ovulation, reducing their odds of conception.

Varicoceles, enlarged veins in the scrotum, may also affect sperm production.
