It has been established that leptin has a stimulating effect on the impulses of gonadotropin-releasing hormone (GnRH), thereby controlling reproductive function [5]. Obesity is associated with many adverse maternal and fetal effects prenatally, but it also exerts a negative influence on female fertility. GH has a stimulating effect on the endometrium and myometrium of the uterus, and in the ovaries it increases the synthesis of estrogen and progesterone, in other words, it plays an important role in the reproductive health of women.

This is often described as a body mass index (BMI) over 30. The effect of weight loss on fertility recovery appears to decrease with age, and in women 36 years and older, weight loss may lead to ineffectiveness in influencing a woman's fertility [6]. When underweight, there is a decrease in leptin levels, which in itself suppresses fertility while excess body weight is associated with increased secretion of leptin, but, nevertheless, this does not guarantee normal fertility. Obesity and female infertility: potential mediators of obesity's impact. It is logical that the ability of adipose tissue to accumulate sex steroids leads to an increase in the steroid pool in women with overweight [5]. For Objectives 1-3, in 2019 we have studied 5 more women who were being treated for infertility. Nat. This text provides a background of scientific evidence to understand the complications that occur after bariatric surgery for all providers responsible for care after surgical intervention. Among other things, insulin also enhances the activity of luteinizing hormone (LH) on granulosa cells, which promotes the activation of steroidogenesis and inhibition of mitosis and leads to inhibition of terminal differentiation of these cells. %PDF-1.6 %���� Machtinger R, Combelles C, Missmer S, Correia K, Fox J, Racowsky C.

Maternal obesity, infertility and mitochondrial dysfunction: potential mechanisms emerging from mouse model systems. Insulin resistance and compensatory hyperinsulinemia, which accompany obesity in women, can contribute to menstrual irregularities, ovulation and, ultimately, fertility. 1,2 Over the past decade, the prevalence of obesity has been increasing worldwide, and now, more than 20% of the population of reproductive-aged individuals living in the U.S. are considered obese. Obesity is a common problem among women of reproductive age. Obese women are more likely to have ovulatory dysfunction due to dysregulation of the hypothalamic-pituitary-ovarian axis.
