Sexual functioning is an important, yet often overlooked, aspect of life quality for many individuals with obesity, especially regarding to man. Fertility and sperm quality are even less explored in the scientific literature. To the best of our knowledge, there is no report of man being a father after bariatric surgery. Here, we report a four men recruited from a prospective cohort of individuals, from both gender, who underwent bariatric surgery in the past three years. The total sample was 192 (146 women – 76.0% and 46 men – 24.0%). From the 46 men, 4 (8.7%) became father of six normal offspring. The ages of the men were respectively: 34; 38; 41; and 43 years of age. These patients were married. The post bariatric surgery pregnancies, from the samespouses before surgical procedures, were without any abnormalities and the newborns presented no congenital anomalies. These individuals referred increased sexual desire after surgery and improvement of erectile function. This case seriesreported highlights the contribution of bariatric surgery in the sexuality, fertility and fatherhood of obese man.
Sexuality is an important element of quality of life in human being. In the context of chronic diseases, such as obesity, this multidimensional construct can be seen under the umbrella of quality of life [1-3]. Bariatric surgery has been the main treatment for obese patients when clinical attempts fail in controlling the body mass index (BMI) and morbidities associated with this condition [4-7]. Among the clinical implications of obesity, sexuality and fertility are less explored in scientific research regarding to indication for bariatric surgery, as well as the outcome of this important aspect of life quality [8-10]. There is increasing evidence that male obesity reduces sperm quality regarding physical and molecular structure of germ cells in the testes. Thus, limiting fertility and the ability of fatherhood [11, 12]. The purpose of this case series report is to document four men who underwent bariatric surgery and developed fatherhood.
The first case is a brown 38-year-old married man with BMI of 47 who underwent bypass bariatric surgery and became free of type 2 diabetes and blood hypertension in the postoperative follow-up. He also improved his sexual desire and intercourse frequency in the prior four weeks before clinical sexuality evaluation. His present BMI is 29. The fatherhood was effective, with the same spouse, one year of postoperative follow-up. The mother pregnancy was without complications and the male newborn was healthy. He also became a father of a second female newborn who presented no congenital anomalies. The gestational ages were respectively 37 and 38 weeks and weights were 2.9 Kg 3.0 Kg.
The second case is a brown 26-year-old married man with BMI of 50 who underwent sleeve bariatric surgery and became free of type 2 diabetes and blood hypertension in the postoperative follow-up. He improved his sexual desire and marginally his intercourse frequency in the four weeks before clinical sexuality evaluation. His present BMI is 44. The fatherhood was effective, with the same spouse, five years after surgery. The mother pregnancy was without complications and the newborn was healthy. Nowadays, this young man is regaining weight and looking forward to redo the bariatric surgery procedure.
The third case is a white 42-year-old married man with BMI of 48 who underwent sleeve bariatric surgery and became free of blood hypertension in the postoperative follow-up. He improved his sexual desire and maintained his intercourse frequency in the four weeks before sexuality evaluation. His present BMI is 36. The fatherhood was effective, with the same spouse, four years after surgery. The mother pregnancy was without complications. Gestational age was 38 weeks and the female newborn was healthy, with birth weight around 3.15Kg and Apgar score at 3 minutes was 10.
The fourth case is a white 44-year-old man with a BMI of 42 who underwent bypass bariatric surgery and became free of blood hypertension in the postoperative follow-up. He marginally improved his sexual desire and intercourse frequency in the four week before clinical sexuality evaluation. His present BMI is 30. The fatherhood, with the same spouse, was effective four years after surgery. The mother pregnancy was without complication and the newborn was healthy. He also had a second healthy newborn.
Infertility and sub-fertility is a frequent clinical finding in obese man, which is proved by reduced sperm concentration, however sperm motility is not yet been proved without any doubt [11]. Additionally, interventions in obese adolescents need to be undertaken carried for through young adulthood aiming at likelihood of being parents [13]. On the other hand, sexual hormones and erectile function are improved in obese men after bariatric surgery after one-year follow-up [9]. However, in summary, to the best of our knowledge fatherhood has not yet been reported in the literature.
There are evidence that scrotal obesity impairs spermatogenesis and consequently the likelihood of being a father in obese men. The mechanism for this is related to increased heat in the scrotal pouch, hormonal changes or molecular damage in the germ cell DNA [11]. Bariatric surgery, reducing BMI can, besides restoration of gonadal hormone levels, better control the temperature in the testis environment and also creating the conditions for improvement in the number and quality of spermatozoids offering improvement in the likelihood of fatherhood. This hypothesis is quite likely for explaining the fatherhood of these four young obese men who underwent bariatric surgery. However, this explanation is controversial and tends to be true after some years (two years) postoperatively [14, 15].
It is important to report that none of these four young obese men had had babies before undergoing bariatric surgery. The presumption is that bariatric surgery improved male hormones, sexuality and the ability of fatherhood. Additionally, although obesity is associated with damage of sperm, nature has provided ways of preserving reservoir of germ cells to maintain human being specie.
Other consideration worthwhile to report is that in the Northeastern region of Brazil, parents are willing to have large family and the average children per family is greater than the Southern and Southeastern of this country, and impairment of fatherhood due to obesity can be one of the reasons for these patients undergoing bariatric surgery. Thus, this surgical procedure is also beneficial to this human construct.
