Andrologia, 2021 Men with nonobstructive azoospermia (NOA), cryptozoospermia and severe oligozoospermia are candidates for microdissection testicular sperm extraction (micro‐TESE) and intracytoplasmic sperm injection (ICSI).

Frontiers in Genetics, 2023 Introduction: Human spermatogenesis is a highly intricate process that requires the input of thousands of testis-specific genes. Defects in any of them at any stage of the process can have detrimental effects on sperm production and/or viability.

Assessment of Correlation between Androgen Receptor CAG Repeat Length and Infertility in Infertile Men Living in Khuzestan, Iran [PDF]
International Journal of Fertility and Sterility, 2015 Background The androgen receptor (AR) gene contains a polymorphic trinucleotide repeat that encodes a polyglutamine tract in its N-terminal transactivation domain (N- TAD).

Fertility of rats with artificial oligozoospermia [PDF]
Reproduction, 1980 Summary. Three different methods to obtain "oligospermic" rats were investigated. (1) Surgical reduction of the amount of tubular tissue diminished the number of spermatozoa present in the epididymis, but the animals were not infertile as long as they were able to ejaculate (32/33 rats). (2) Treatment with oestradiol benzoate on the 5th day after birth

Approach to the Patient With Oligozoospermia [PDF]
The Journal of Clinical Endocrinology & Metabolism, 2013 Male infertility affects 1 in 20 men and is the sole or contributory factor in half of assisted reproductive treatments (ARTs). A reduced sperm density (oligozoospermia) is often accompanied by poor motility and morphology reflecting qualitative and quantitative defects in spermatogenesis.

Sperm transcriptome profiling in oligozoospermia [PDF]
Journal of Assisted Reproduction and Genetics, 2011 Investigate in what extent sperm transcriptome of infertile men is different from that of fertile individuals.Semen samples were collected for determination of sperm parameters as well as for RNA isolation. Gene expression profile was investigated in spermatozoa of 8 infertile and 3 fertile men by microarray analysis using the Affymetrix Chip HG-U133 ...

Perturbation of genomic imprinting in oligozoospermia [PDF]
Epigenetics, 2009 The role of epigenetic modifications in oligozoospermia and other disorders of spermatogenesis remains poorly understood. While a variety of environmental, nutritional and genetic abnormalities can cause oligozoospermia, a condition associated with infertility, it is unclear whether chromatin modifications might be also involved in impaired ...

Mustadi Yapana Basti (medicated enema) in the management of oligozoospermia: A case series
Indian Journal of Health Sciences and Biomedical Research KLEU, 2023 Infertility is a global issue of concern in the modern era, affecting 8%–12% of couples globally. Although the etiology of infertility is varied and difficult to determine, a good proportion of cases can be attributed to male.
