    • 여성의 난소에서 한 개의 난자가 한 월경 주기 동안에 나온다. 
    • 한번 사정될 때 남성의 고환에서 3~5 억 개의 정자들이 나온다. 
    • 수 억 개의 정자들 중 한 개의 정자가 한 개의 난자를 만나서 수정란이 되고 그 수정란이 아기가 된다. 
    • 남성 성염색체는 XY로 표시하고 여성 성염색체는 XX로 표시한다. 
    • Y 성염색체에 의해 아들이 되든지 딸이 되는 것이 좌우된다. 
    • 즉 아기의 성염색체가 XY이면 아들이 되고 아기의 성염색체가 XX이면 딸이 된다. 
    • 난자와 정자가 만나 수정이 된  바로 그 순간부터 아들이 되고 또는 딸이 되는 것이 결정된다.

  • • o One egg is released from a woman’s ovary during one menstrual cycle.

o Each ejaculation releases between 300 and 500 million sperm in a man’s testicles.

o One sperm out of hundreds of millions of sperm meets one egg and becomes a fertilized egg, and the fertilized egg becomes a baby.

o Male sex chromosomes are denoted as XY and female sex chromosomes are denoted as XX.

o The Y sex chromosome determines whether a child becomes a son or a daughter.

o In other words, if the baby’s sex chromosome is XY, it becomes a son, and if the baby’s sex chromosome is XX, it becomes a daughter.

o From the moment the egg and sperm meet and are fertilized, the decision to become a son or a daughter is determined.

o Parents should also become anti-doctors – Encyclopedia of Pediatric and Family Nursing] – See Volume 25 Pregnancy, Delivery, Childbirth, and Newborn Care.
