Before we focus on infertility and its causes, it is important to first understand how the female reproductive system works during the menstrual cycle. The cycle is set in motion with the release of an egg from the ovaries, which is made possible by the action of ovarian follicles. These follicles are first stimulated by the brain’s pituitary gland, which releases a hormone, thus initiating the cycle.
During the course of the menstrual cycle, various hormones are produced to facilitate the process with Oestrogen (supports follicle growth) and Progesterone (to make the uterus ideal for pregnancy) being the most notable of the lot.
Following ovulation, the sperm cells and egg meet in the fallopian tube, with one of the sperm cells accepted by the egg. Fertilisation is said to have occurred when the sperm cell penetrates the outer layer of the egg. This fertilised egg then continues its journey to the uterus and once the egg implants itself into the lining of the uterus, pregnancy is said to have occurred. If however, the egg isn’t properly fertilised or if the embryo fails to develop, the lining of the uterus is shed as a menstrual period about 14 days after ovulation.
Infertility fundamentally refers to the inability to conceive offsprings. In more specific terms, it is the inability to achieve pregnancy by a couple of reproductive age after one whole year of unprotected sexual activity. Primary Infertility is a term used to define infertility in a couple who are yet to have their first child. Secondary Infertility is the failure to conceive after a previous pregnancy. However infertility is not the end of the road, for options like IVF treatment can always lead to a successful pregnancy and it is wise to consult a doctor and understand the options available in every case.
Statistics suggest that roughly one in three cases of infertility can be explained by female causes. These causes may be physical, hormonal or simply age-related. Once the exact cause of infertility has been determined, the doctor will be able to make recommendations on the course of treatment that needs to be adopted.
Diet can play a part in affecting a woman’s fertility and chances of pregnancy. Studies have shown that consuming low-fat dairy products more than twice a day face an 85% risk of suffering from ovulatory infertility, wherein infertility is caused by a failure to ovulate. An iron-rich diet, on the other hand, can go a long way in lowering the chances of ovulatory infertility. Beans, lentils, eggs, spinach, whole grains and fortified cereals can all be consumed, supplemented by foods rich in Vitamin C, like bell peppers, berries and citrus fruits to enhance iron absorption.
It is also recommended to avoid trans-fat and add foods containing monounsaturated fat to the diet. Avocados, nuts, whole milk and olive oil or sunflower oil are safe bets in this regard. In fact, it has been found that women who consume at least one serving of whole milk per day reduce the risk of ovulatory infertility by more than 50%, as opposed to women who don’t.
Calcium – rich foods need to be consumed while replacing animal-based protein with vegetable-based protein can improve fertility vastly by helping maintain a healthy weight without compromising on nutrition requirements. Leaving the usual suspects for the conclusion, nicotine, alcohol, and caffeine all need to be avoided at all costs.
