What is conception, and what techniques can be used to assist conception? 

Here is a tip:

Parents who cannot conceive through the natural methods can do so by using artificial scientific interventions. 


Conception refers to the process of conceiving a child. After intercourse, the sperm can survive in the female body for six days, which means that a woman can conceive anytime in between these six days.


When natural methods fail, many parents move toward artificial techniques:

  • In vitro fertilization-This artificial reproductive technique is used to assist conception in which several ova are removed from a female's ovary and are manually made to fertilize with the sperm in a laboratory setting, after which it is placed inside the female's uterus. 
  • Artificial insemination- This artificial reproductive technique is used to assist conception in which the sperms are injected into the female's uterus. The sperms are given either by the female's partner, or by a donor.

Verified Answer

When the female has intercourse with a fertile man at the time of ovulation, male eggs called sperms are released in a large quantity at a time.


Usually, fertilization takes place within 12 hours of ovulation. Once the sperm enters the ovum, fertilizes the ovum, and repels other cells to enter the same ovum, life begins. This is called conception.


The techniques involved in assisting conception are:

  • In vitro fertilization
  • Artificial insemination
