| Summary: | Background: Male factor infertility is a health problem that affects millions of couples
around the world. Male factor infertility is responsible for approximately more
than half of all cases of infertility. About 15% of men and 10% of women with
infertility may have genetic abnormalities, including chromosomal abnormalities
and single gene mutations. In this study, results of genetic analys is of the
infertile male patients who underwent testicular sperm extraction (TESE) with the
diagnosis of non-obstructive azoospermia were evaluated in order to reveal
genetic defects that impair or prevent spermatogenesis in male infertility. Methods: We compared the results of peripheral blood chromosome analysis,
molecular karyotyping, male infertility genetic panel, and also testosterone,
prolactin, follicular stimulating hormone and luteinizing hormone levels in
non-obstructive azoospermic infertile patients aged 26–44 years, and
investigated the relationship between these parameters and genetic mutations. Results: As
a result of this research, among 26 patients, INSL3 (insulin-like
peptide 3) gene mutation, which is considered pathogenic according to
the criteria published by the American College of Medical Genetics and Genomics
(ACMG) was detected in 1, FSHR (follicle stimulating hormone
receptor) gene polymorphism in 17, CFTR (cystic fibrosis
transmembrane conductance regulator) mutations in 5, CATSPER1
(cation channel sperm associated 1) and TEX101 (testis
expressed 101) in 1, LHCGR (luteinizing
hormone/choriogonadotropin receptor) in 1, ZMYND15 (zinc finger
mynd-type containing 15) in 1, DNAH5 (dynein axonemal heavy
chain 5) in 2, and DNAH11 (dynein axonemal heavy chain
11) changes in 1 patient. In the chromosome analysis, 47XXY Klinefelter
syndrome was observed in 6 patients. Conclusions: The results have shown that non-obstructivea
zoospermic patients with complaints of infertility may have other genetic
abnormalities leading to infertility, despite the results of chromosomal analysis
of the peripheral blood samples were within normal reference limits.
Investigating these underlying genetic disorders helped us find the cause of
infertility in ourpatient population. |
