The present study systematically investigated the relationship between sex hormones and leptin in men. In this study, 70 articles were reviewed and the subject was investigated by searching the words "Leptin", "Patients undergoing surgery" and "Sex hormone". Leptin is a hormone derived from adipose tissue that plays a major role in the pathogenesis of obesity. Hyperinsulinemia and insulin resistance are among the complications of obesity. Hyperinsulinemia is one of the factors that seems to affect the leptin hormone level. Few studies have investigated the relationship between leptin and insulin resistance in obesity in children and adolescents. Leptin is made by fat cells, and for this reason, with the presence of these cells and the increase in messaging, when the leptin hormone increases, the message of satiety is sent to the brain; As a result, the person reduces his food consumption. However, sometimes due to the excessive increase of leptin caused by eating sweet and fructose-containing foods, the brain loses its sensitivity to the leptin hormone and does not receive the message of satiety. For this reason, leptin hormone and obesity are related to each other; But their relationship cannot be considered linearly. In many cases, after testing the obesity hormone leptin, the doctor concludes that a person who is overweight has developed a strong resistance to the hormone leptin; Therefore, by prescribing some solutions, such as reducing the amount of fruit consumption, increasing the regularity and hours of rest and sleep, reducing the consumption of sugary foods and changing the diet, as well as consuming enough water, it tries to increase the sensitivity of the brain to the leptin hormone. The results of the recent study showed that the relationship between leptin and insulin resistance was weak and after controlling for body mass index, the relationship disappeared.

Infection with the corona virus leads to short-term and long-term effects, which sometimes affect the sufferers for the rest of their lives. The effect of Corona on the human brain has been studied by many scientists. The new symptoms that have been observed in patients suffering from the disease of Covid-19 indicate the effect of the corona virus on the functioning of the human brain and nervous system. While examining and treating patients in New York, which is considered to be the most prominent state in America in terms of infection with the corona virus and the number of victims of the Covid-19 disease, apart from fever, cough, body pain and shortness of breath, new signs of the destructive effect of the corona virus on human health. They found that the brain and nervous system of the patients are also somehow involved in this disease. Among the characteristics of this new finding is confusion, forgetfulness and even convulsions caused by nervous pressure in patients with Covid-19, many cases of which have been observed in New York state; In such a way that some patients do not even know where they are and why they are in the hospital or what year we are in now. In most cases, these symptoms are related to the lack of oxygen in the blood; However, it has been observed that this memory disorder in some patients is not very proportional due to the level of pulmonary involvement with the virus. "Jennifer Frontera", a neurologist at Langone University Hospital in Brooklyn, one of the old parts of New York City, believes that according to the new findings, the issue of involvement of the brain and nervous system when contracting the new type of corona virus is now seriously discussed in it has been investigated.
