Why Does Your IVF Fail? It may be Related to Male Age

Whether IVF can succeed or not, many people may think it has something to do with women, which is wrong. Although female fertility will decline over time, so will men. Is the success rate of IVF related to male age? With the increase of age, men's fertility rate also shows a downward trend, and the risk of infertility also increases. Genetic changes of sperm DNA, male infertility caused by gene mutation, increased risk of genetic diseases, and increased incidence of adverse pregnancy will affect the success rate of IVF. Physiological factors. With the growth of age, the endocrine function and spermatogenic function of testis gradually weakened, androgen level decreases, semen volume decreases, sperm motility decreases, abnormal sperm increases, etc., which will have adverse effects on male fertility. The results showed that the total amount of sperm began to decrease after 35 years old, and sperm concentration, forward motility, and normal morphology significantly reduced after 40 years old. Psychological factors. With the growth of age, the pressure from work and family also increases. Mental stress will lead to decreased sexual desire, erectile function, and ejaculation dysfunction and lead to a large number of abnormal sperm production, leading to male infertility. Pathogenic factors. With the increase of age, the probability of male diseases is also increasing, such as prostatitis, epididymitis, seminal vesiculitis, etc. These diseases will lead to male infertility. The sperm quality is one of the critical factors related to the success of IVF. If the number of sperm is small, and the survival rate is low, the success rate of IVF will also be affected. Therefore, before the IVF, both men and women need to practice the inspection. For sperm quality problems caused by these reproductive system diseases, the commonly used safe and effective treatment is herbal medicine Diuretic and Anti-inflammatory Pill. What are the requirements of IVF for men? Quit smoking 2-3 months before IVF. Smoking not only affects health but also reduces sperm quality, which affects pregnancy and embryo development. The incidence of congenital mental retardation and malformation is also relatively high. With the increase in smoking, sperm deformity rate increased significantly, and sperm motility decreased significantly. In general, the husband needs to quit smoking 2-3 months before IVF to have enough time to produce high-quality sperm. Pay attention not to be sedentary. Sitting in front of the computer for a long time will affect the heat dissipation function and blood circulation of the testis, increase the testis' local temperature, and affect the production of sperm. Pay attention to the effect of tight clothes on spermatogenesis. Tight pants and jeans will squeeze the scrotum for a long time and affect the normal production of sperm. Fathers should choose loose and breathable clothes when preparing for IVF. Environmental factors also need to be paid more attention. Radiation is known to cause injuries and congenital disabilities. Other substances that are considered harmful to sperm include some perfume containing two benzoates (or ester), some insecticides, organic mercury, polychlorinated two benzene, and estrogen in tap water. Many of these substances are still under study. Do IVF baby before and after a period of time to refuse alcohol, drinking will damage the liver and damage the quality of sperm to reduce reproductive capacity. Alcohol can reduce the level of testosterone and the quality and quantity of sperm. Pay attention to testicular temperature. Men's testicles are installed in the scrotum because the temperature of the testicles can be lower than that of the body so that the testicles can work normally. Under normal circumstances, the temperature of the scrotum should be 4 ℃ lower than the body temperature. Remember that sitting in the scrotum or driving will affect sperm temperature. The success rate of IVF depends on many aspects, endocrine and laboratory conditions, and technicians' technical level. Of course, it also depends on the patient's age. The state of the womb and ovary of the female and the sperm of the male, etc., are all factors affecting the success rate.
