How Male Infertility Is Related to Obesity

Obesity is a major health issue with an average of about 1.6 billion men and women causing overweight. Studies show that since 1970’s the level of obesity is triples among men which is the reason for many men being infertile or facing reproductive complications. Along with consuming alcohol, lifestyle and medications, obesity is another factor responsible for men being infertile and their less participation in their partner’s conception and pregnancy. This is the reason for couples moving towards artificial reproductive technologies that includes IVF (In vitro fertilization) and IUI (Intrauterine insemination).

It is well understood that male infertility can be affected by obesity and excessive weight can lead to many other problems including reproductive functioning of both men and women. Obesity is changing the physiological as well as molecular framework of germ cells in testes, reducing sperm count and also affecting sperm quality and quantity. A major drawback of male infertility is it impairs kids metabolic as well as reproductive well being along with the hazards caused to the men themselves. Since, infertility is also a genetically transferred, there are chances of child’s infertility or the child carrying less reproductive genes. There are proofs that maternal obesity can affect children’s metabolism causing diseases like diabetes and many other problems. The growing obesity and its affect on male fertility is a topic of concern and there should be steps taken to sensibly handle this arising situation, here we will discuss how male infertility is related to obesity.

How male obesity affects fertilization and conception?

Previously it was considered that woman’s obesity affects the eggs or oocytes preventing healthy embryo development, but the latest studies confirm male obesity is an equal threat to the embryo growth of the partner adversely affecting embryo development and minimizing successful pregnancy results. Further, according to researches male obesity affects fertilization as well as conception.

There are observances that the spouses with obese or wrong BMI have greater odds carrying pregnancy than those having spouses with normal weight. Couples with normal weight are considered more viable for carrying a child as compared to those suffering from obesity. Obesity in males results in diminished pregnancy rates as well as declined maternity in married couples and aroused complication in birth or conceiving. Obesity results in lowered blastocystic development, fertilization as well as less sperm building for couples undergoing IVF treatment. Additionally obesity also causes dysfunctionality of ovulation cycle in women and infertility. The embryologists and specialist suggest that male obesity during pregnancy impairs embryo well being minimizing implantation and reducing birth rates.  

Sperm specifications and male obesity

Various scientific studies have showed the relation between male obesity and sperm specifications and how male obesity affects sperm specifications. WHO (World health organization) says that male obesity affects sperm specifications including sperm motility, attentiveness and morphology. According to studies male obesity can lead to decreased sperm motility, decline in sperm ratio and deceased sperm quantity as well as quality, however it is essential to know the contrast between species. The research also shows that high-fat diet can lead to reductions of testosterone and changed glucose homeostasis, sperms are however decreased when the male faces excessive weight gain or obesity.

Sperm DNA integrity, oxidative stress and male obesity

Human studies along with animal research proves that there is an important relationship between obesity and lower sperm DNA integrity, however there are many methods to evaluate sperm DNA integrity. Studies conclude that men BMI highly affect the oxidative stress level, higher the weight more will be the oxidative stress. It is getting more clearer that male obesity is connected with substantial alterations to the molecular structure of sperm that has ramifications for its own functionality and also for the resulting embryo articulated.

It is clear that male obesity is related to the infertility level in me, obesity not only harm the functionality of male reproductive systems it also reduces the sperm count, quality and quantity of the sperm. There are many evidences to suggest that obesity in men resulted to the problems in conception and women getting pregnant. Taking this as a serious concern, there should be steps taken to talk and solve this hindering fertility situation.
