Solution
- Females are often blamed for the couple being unable to reproduce because there is lack of awareness about the issue. As a biology student, I would promote the following two values among people:
- Either of the partners could be responsible for the couple being childless.
- We must not blame females for infertility without proper diagnosis.
- Two reasons for infertility could be congenital disease and drugs.
- There are various techniques which can help in the condition when the male partner is infertile. One such technique is artificial insemination. In this technique, the semen collected from the husband or a donor is introduced into the vagina or uterus. This cures infertility arising from the inability of the male partner to ejaculate or due to his low sperm count.
