The gr/gr deletion(s): a new genetic test in male infertility?
Y chromosome microdeletions are the most frequent genetic cause of severe oligozoospermia (,5 million spermatozoa/ml) and azoospermia (absence of spermatozoa in the ejaculate). Microdeletions associated with infertility occur in specific regions of the long arm of the Y chromosome, called azoospermia factor (AZF) regions. 3 In 1996, three types of AZF deletion (AZFa, AZFb, and AZFc) were descri...
متن کاملNew genetic markers for male infertility.
PURPOSE OF REVIEW The purpose of this review is to highlight the most important advances in the field of genetics of male infertility, with particular attention to primary articles dealing with the identification of new genetic and epigenetic markers that could be translated into clinical practice in the near future. RECENT FINDINGS Copy number variations (CNVs) of the Y chromosome (gr/gr) de...
متن کاملThe role of Y chromosome deletions in male infertility.
Male infertility affects approximately 2-7% of couples around the world. Over one in ten men who seek help at infertility clinics are diagnosed as severely oligospermic or azoospermic. Recent extensive molecular studies have revealed that deletions in the azoospermia factor region of the long arm of the Y chromosome are associated with severe spermatogenic impairment (absent or severely reduced...
متن کاملGenetic Testing in Male Infertility
Infertility is a major health problem which affects approximately 22% of married couples in reproductive age. The apparent increased incidence of male infertility, in parallel with the widespread use of in vitro fertilization (IVF), raises concern as to the impact of advanced assisted conception techniques in transmitting genetic anomalies to the offspring. Recent research has widely focused on...
متن کاملGenetic Causes of Male Infertility
Infertility is a major health problem today, affecting about 15.0% of couples trying to have a child. Impaired fertility of the male is causative in 20.0% of infertile couples and contributory in up to another 30.0-40.0%. Infertility already affects about 5.0-7.0% of the general male population and may further increase in the future, considering the apparent trend of declining sperm count in in...
