The discovery of antibiotics was one of the greatest boons to mankind. It is because of those many of us are here today. However, excessive usage of it over the period of time has lowered the effectiveness of antibiotics, while, the proliferation of micro-organisms is still predominant. There have been various studies conducted on understanding the side effects of antibiotics on fertility. Below are some of the findings:
1. Male and female fertility - Tetracycline, one of the commonly used antibiotic is known to cause infertility in men. They act by tempering with the sperm's motility and counts. Studies conducted on spiders revealed that, there was a significant 25% decrease in fertility in the male spiders who were being administered by Tetracycline. It does not seem to impact female fertility. However, it is advised not to take it during pregnancy. It is best suggested to consult a doc before beginning to plan for a baby and get the boxes ticked right for usage of antibiotics.
Recent studies have confirmed that, antibiotics are not the cause for birth defects of fetus.
2. Menstrual cycles - The cycles are mainly regulated by production of two important hormones, Estrogen and Progesterone. Antibiotics tend to interfere with the normal functioning of Estrogen, thereby causing a delay in periods or resulting in an an-ovulatory cycle. Estrogen hormone is metabolised by liver. In the presence of antibiotics, this hormone will be metabolised faster, making it less available in the blood stream. Antibiotics not only kill the bad bacteria resulting infection, but at times kill the native bacteria necessary for breaking Estrogen into active molecules and releasing it in blood. Thus the pituitary gland doesn't get enough information on its further action, resulting in a late ovulation or period.
