Inm-8: Assisted Reproductive Technologies and Genetics
Genetic causes have a considerable involvement in infertility. Well-known examples are some chromosomal translocations or sex-chromosomal abnormalities and Y-chromosome deletions. The most common chromosomal aberrations associated especially with severe oligo- and azoospermia are sex chromosome aneuploidies and chromosomal translocations. Consequently, occurrence of aneuploid embryos will lower...
متن کاملAging and male reproductive function: a mitochondrial perspective.
Researching the effects of aging in the male reproductive system is not trivial. Not only are multiple changes at molecular, cellular and endocrine levels involved, but any findings must be discussed with variable individual characteristics, as well as with lifestyle and environmental factors. Age-related changes in the reproductive system include any aspect of reproductive function, from dereg...
متن کاملGenetics and skin aging
Skin aging is a complex process and underlies multiple influences with the probable involvement of heritable and various environmental factors. Several theories have been conducted regarding the pathomechanisms of aged skin, however fundamental mechanisms still remain poorly understood. This article addresses the influence of genetics on skin aging and in particular deals with the differences o...
متن کاملTelomeres and Reproductive Aging
Telomeres are special deoxyribonucleic acid (DNA) structures that “cap” the ends of eukaryote chromosomes. The term telomere derives from the Greek words telos, meaning “end”, and meros meaning “part”. The existence of these end-parts of chromosomes was first suggested in 1938 by Muller (Muller, 1938). Telomere length is involved in biological aging and disease processes. Telomere length is aff...
متن کاملGenetics and Male Infertility
Male are the sole cause of infertility in approximately 20% of infertile couples and are an important contributing factor in another 20-40% of couples with reproductive failure. Male infertility can result from a variety of causes. Some, like ductal obstruction and hypogonadotropic hypogonadism, can be accurately defined and effectively treated. Genetic abnormalities can cause infertility by in...
