Bromocriptine for idiopathic oligo/asthenospermia

Cochrane Database of Systematic Reviews, 1996
Oligo-astheno-teratospermia (sperm of low concentration, reduced motility and increased abnormal morphology)of unknown cause is common and the need for treatment is felt by patients and doctors alike. As a result, a variety of empirical, non-specific treatments have been used in an attempt to improve semen characteristics and fertility.

Differentially expressed miRNAs and potential therapeutic targets for asthenospermia

Andrologia, 2021
Asthenozoospermia is detected in 40% of infertile men, and characterised by low sperm motility. MicroRNAs (miRNAs) play essential roles in spermatogenesis, but little is known regarding the function of seminal plasma miRNAs in asthenozoospermia. In this study, we collected seminal plasma samples from patients with asthenospermia and healthy men and ...

Multi-tailed spermatozoa in a case with asthenospermia and teratospermia

Virchows Archiv B Cell Pathology, 1978
A case is presented of an infertile male whose spermatozoa showed low mobility, a high percentage of irregular large heads and a variable number of tails (between 0 and 4). In the spermatozoa with several tails each axoneme, surrounded by its own outer fibres and mitochondrial sheath, arose from its own basal plate. Throughout the middle piece of every
