Question

Cite a situation in which both man and woman contribute to subfertility.

Short answer

A situation where both man and woman contribute to subfertility can be when the woman has a condition such as PCOS, which impairs regular ovulation, whereas the man has a low sperm count, hindering the chances of a successful fertilization.

Step-by-step solution

Define Subfertility

Subfertility is a state of reduced fertility, where a couple has an diminished chance of becoming pregnant even after a year of unprotected sexual intercourse.

Identify the Causes in Men

There are several reasons why a man might be contributing to subfertility. These include low sperm count, poor sperm mobility, abnormalities in sperm morphology, and medical conditions such as Varicocele.

Identify the Causes in Women

Causes of subfertility in women may include anovulation (not ovulating, or releasing an egg), blocked fallopian tubes, endometriosis, or polycystic ovary syndrome (PCOS). Age can also be a factor, as fertility tends to decrease after the age of 35.

Provide A Suitable Scenario

A situation wherein both man and woman could contribute to subfertility is when a woman has a medical condition like PCOS, which interferes with regular ovulation, and the man has low sperm count. In this case, the couple's chances of conceiving are reduced because the woman's egg release is unpredictable and the man's sperm count is insufficient to fertilize the egg if released
