It includes the assessment of the ejaculate volume, sperm concentration, motility, and morphology using WHO criteria [ 34 ]. Another important aspect of this problem in India is that it is the wife alone who has been traditionally blamed for sterility. Lifestyle factors, including age when starting a family, nutrition, weight management, exercise, psychological stress, cigarette smoking, recreational and prescription drugs use, alcohol and caffeine consumption, may impact fertility [ ]. But these changes are not great enough to account for the significant changes in sexual function. While the effect of maternal ageing on fertilization and reproduction is well known and several studies have shown that women over 35 years have a higher risk of infertility, pregnancy complications, spontaneous abortion, congenital anomalies, and perinatal complications. The ovary has no capacity to regenerate oocytes. There is a dramatic similarity in the genetic preparation of the egg for fertilization which occurs under the influence of FSH and LH during each monthly menstrual cycle, and the changes that early spermatogonia go through in the male testes during a 3-month cycle, to result in the release of mature spermatozoa. The AZF microdeletions are the prevalent cause of male factor infertility. These germline or heredity mutations also may contribute to the association of advancing paternal age and disorders in the offspring, such as these children being diagnosed with autism and schizophrenia.

Keywords: secondary male infertility, old men, androgen deficiency, varicocele, testosterone, andropause. Paternal age and sporadic schizophrenia: evidence for de novo mutations. A review of the literature revealed that no age difference was taken into account while managing secondarily infertile men, as most researchers and authors believe that the causes of primary and secondary male infertility are similar. Studies have consistently shown that increasing male age is associated with an increased time to pregnancy and decreased pregnancy rates.
Consider what cause male infertility elderly thanks
An association between human male elderly and chromosomal infertility has been known for a long time [ 56, 57 ]. De novo male revealed by whole-exome sequencing are cause associated with autism. Alterations in epigenetic mechanisms like parental imprinting can also have negative implications on the offspring [ ]. A Study conducted by Gorpinchenko et al. The chance of the child having some what or chromosomal problem also gets higher when you get older.
