Dietary and lifestyle-related factors behind delayed conception in females.

Delayed conceiving is a failure of a female to attain clinical pregnancy within a year without the use of contraception or any precautionary measure. The females of reproductive age (20-49 years) are the sufferers, that is, about 1.5 million or 10% of couples globally are facing this issue. Delayed conception can be caused by several reasons including diet, lifestyle, and genetic and clinical problems. Deficiencies or overconsumption of any nutrient may also cause delayed conception in females. Dietary deficits such as iron, iodine, zinc, folate, and vitamin D reduce the ovarian reserve. Heavy metals such as copper, manganese, lead, and cadmium also have an impact on fertility. Overconsumption of fast foods and nonhome-made foods increases the likelihood of infertility by 2-3. Smoking, physical activity, age, polycystic ovary syndrome (PCOS), obesity, and depression have all been considered lifestyle and clinical factors. If women have a sedentary lifestyle, too much exercise or obesity both contribute to infertility. In clinical factors, type 1 diabetes, insulin resistance, and hypertension mainly cause infertility. Our focus in this review is on the studies probe that how these variables contributed to delayed conception and how it can be controlled to help combat infertility. Prevention from delayed conception involves consuming a healthy and balanced diet that contains essential nutrients engaging in physical activity and abstaining from smoking, PCOS, and medical issues.
