Does Fasting Affect Fertility For Those Who Want To Have a Child?

By Medically reviewed by Panel Perubatan Hello Doktor

If you and your partner are seeking a pregnancy, there must be a concern if fasting will affect fertility. This concern is quite reasonable because there is a possibility that the schedule of meals during fasting is drastically different from normal, thus some hormones can go haywire. So, is it true that fasting affects fertility?

Does fast affect female fertility?

In a study conducted by researchers at Harvard University in collaboration with Massachusetts General Hospital (MGH), it was found that restricting calorie intake in adult female mice could prevent abnormalities in pregnancy.

In this study, the scientists monitored two groups of adult female mice aged three months to a year. This study looked at how diet could affect the quality of the eggs and the fertility of the lab mice. One group was fed as much as possible during adulthood, while the other group was limited to seven months of dietary intake and was given plenty of food just before the study ended.

As a result, groups of mice that were allowed to eat freely experienced a decrease in the number of eggs produced when ovulation. Meanwhile, eggs from a group of mice that restricted their intake of food have more healthy egg cells.

Research on other animals, such as female monkeys, also yields the same conclusions. With this, the researchers also expect the same can happen to humans, especially adult women when it comes to diet and fertility.

As a conclusion, based on these research, fasting might not affect the fertility of women. In fact, these studies stated that fasting has many benefits, including the prolonging the fertile period of women and even increasing the number of eggs produced.

This is all due to a reduced caloric intake in your body during fasting which reduces blood sugar levels and affects reproductive hormones. Thus, women who diet or fast tend to have a normal menstrual cycle and healthy egg production.

What about sperm quality?

Fasting also will not adversely affect the quality of sperm. Fasting can actually improve the functioning of reproductive organs. Acid and alkaline levels in the body will be balanced out during fasting so that the function of various organs of the body can increase.

With less food intake in a long time, various types of bacteria, viruses, germs, to harmful cells such as cancer cells will not be able to survive. In addition, fasting also provides an opportunity for the digestive system to rest, allowing various toxins and impurities that can damage your health to be removed.

To maintain the quality of sperm and eggs during fasting, it is better to consume a balanced diet at breaks and keep check of your fluid levels.
