Sexy TIMES!Reproduction and Sexual intercourseWhat 2 things do you need to make a baby?
  • 1. Sperm from the male
  • 2. An ovum (egg) from the female
  • In order to create new life, a sperm cell must join and enter an ovum (fertilization)
  • How many days can an ovum survive once released?
  • The ovum generally has a lifespan of one day. If it is not fertilized, it will disintegrate and gradually be discharged in the menstrual flow.
  • (and no, you can’t see the egg in the toilet! It’s microscopic)
  • How many days can a sperm survive once in the vagina/uterus?
  • The sperm’s lifespan is up to 5 days.
  • If the sperm cell enters the ovum, fertilization occurs.
  • What is a chromosome?
  • Chromosomes contain all the genetic material that makes the newly developing human unique
  • Ex: hair colour, eye colour, body size and shape, etc.)
  • How many chromosomes does a sperm/ovum contain?
  • A sperm contains 23 chromosomes
  • An ovum contains 23 chromosomes
  • Each chromosome matches the corresponding chromosome from the other parent, forming 23 numbered pairs.
  • What happens with less or more chromosomes?
  • Most fetuses with chromosomal anomalies are miscarried during the first trimester.
  • First trimester:
  • Week 1 – Week 12 (first 3 months of pregnancy)
  • Most of those who survive have Down syndrome; it's caused by an extra chromosome 21.
  • What does the “X” and “Y” chromosome mean?
  • X = female
  • Y = male
  • Does the Sperm or Ovum decide on the sex of the baby?
  • The sperm (father) contributes the X or Y chromosome that will decide the sex of the baby.
  • Ex: The mother’s ovum has two XX chromosomes (female). The father’s sperm has XY chromosomes (female/male). Each parent contributes ONE of those two chromosomes.
  • How are fraternal twins (non-indentical) made?
  • If two eggs are released during ovulation and both are fertilized by a different sperm, fraternal twins are created.
  • How are identical twins made?
  • When one ovum is fertilized but splits into two eggs.
  • For the first two months, what is the baby called?
  • The baby is called an embryo for the first 8 weeks (2 months) and kinda looks like a little alien!
  • What is the baby called from 8 to 40 weeks?
  • The baby is then called a fetus for the rest of the pregnancy.
  • Where is the ovum fertilized?
  • The ovum is fertilized in the Fallopian tube, where it then moves into the uterus and imbeds itself in the thick, nourishing lining.
