Genetic alterations that can cause infertility


Among the main constitutional genetic anomalies (affecting your whole body and diagnosed in a blood sample) that can affect the fertility of a person are genetic alterations. There are two types: chromosomal level and single-gene level.



Are those that affect the structure or the number of chromosomes.

Numerical chromosomal abnormalities (extra or missing full chromosome) such as Klinefelter syndrome (47, XXY) or 47, XYY are related to infertility are in case of evils. Monosomy X (Turner syndrome) or 46, XY syndrome in case of women are causative of infertility, among others.

Structural chromosomal abnormalities: extra or missing parts of a chromosome can affect fertility (such chromosome and microdeletions).

Chromosomal translocations and inversions do not usually affect the health of the carrier, but they are frequently related to infertility and miscarriages.

Karyotype analysis in blood is nowadays strongly recommended in all couples prior to any assisted reproduction procedure.


Genetic (single-gene)

There are different genetic syndromes that manifest male or female infertility such as fragile X syndrome (FMR1), Kartagener syndrome, disorders of sex development, Kallmann syndrome, ambiguous genitalia and androgen insensitivity, thrombophilia or congenital bilateral absence of vas deferens (CFTR), etc. In some of the syndromes, infertility is only an accompanying manifestation but in others can be the main or only symptome. A good assessment of your clinical history will help to indicate whether or not you need a specific genetic test.


There are other genetic tests that can be performed in a Sperm Sample, recommended in cases of abnormal semen analysis such as sperm Aneuploidy analysis by FISH (chromosomes 13, 18, 21, X and Y) and Sperm DNA fragmentation.
