Chromosomal disorders and male infertility [PDF]

, 2015
Male factor infertility is considered a complex disorder with a largely unknown etiology that affects about 7% of men. In general, genetic abnormalities account for 15%-30% of condition and Y chromosome microdeletions are also frequent.

Effects of AZFc (b2/b4, b1/b3, b2/b3, and gr/gr) deletions and primary duplications on the outcomes of the first intracytoplasmic sperm injection treatment cycle: A single‐center retrospective cohort study

Andrology, EarlyView.
Abstract Background Current advances in high‐throughput sequencing technology enable the precise identification of Y chromosome microdeletion and primary duplication in infertile couples, but the mechanism and clinical significance of these mutations in assisted reproductive techniques remain unclear.

Deletion of GOLGA2P3Y but not GOLGA2P2Y is a risk factor for oligozoospermia [PDF]

Reproductive BioMedicine Online, 2016
The AZFc locus on the human Y chromosome harbours several multicopy genes, some of which are required for spermatogenesis. It is believed that deletion of one or more copies of these genes is a cause of infertility in some men. GOLGA2LY is one of the genes in the AZFc locus and it exists in two copies, GOLGA2P2Y and GOLGA2P3Y.

CAG repeats polymorphism of androgen receptor gene, Kennedy’s disease and male infertility

Андрология и генитальная хирургия, 2019
Genetic factors are a common cause of severe pathozoospermia and male infertility. An increase in the length of trinucleotide repeats causes a number of progressive neurodegenerative diseases, including spinal bulbar muscular atrophy — Kennedy syndrome ...

Meiotic outcome in two carriers of Y autosome reciprocal translocations: selective elimination of certain segregants [PDF]

, 2017
BACKGROUND: Reciprocal Y autosome translocations are rare but frequently associated with male infertility. We report on the meiotic outcome in embryos fathered by two males with the karyotypes 46,X,t(Y;4)(q12;p15.32) and 46,X,t(Y;16)(q12;q13).

Luteinizing hormone receptor knockout mouse: What has it taught us?

Andrology, EarlyView.
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

Intrauterine insemination of washed spermatozoa for treatment of oligozoospermia [PDF]

International Journal of Andrology, 1995
SummaryEfficacy of intrauterine insemination (IUI) using washed spermatozoa for treatment of oligozoospermia was evaluated by a prospective randomized study in 50 couples, using LH‐timed natural intercourse in the alternate menstrual cycles as a control.
