Deficiency of TBL1XR1 causes asthenozoospermia

Andrologia, 2021
Transducin (β)-like 1 X-linked receptor 1 (TBL1XR1) is an evolutionarily conserved protein related to spermatozoa. To clarify its role and mechanism of action in spermatozoa, qRT-PCR was used to analyse the expression of TBL1XR1 in human spermatozoa and mouse testes.

Pentoxifylline Treatment of Asthenozoospermia

Andrologia, 2009
Nine asthenozoospermic men were treated by 1.200 mg/day of pentoxifylline for a period of 2 to 5 months. There was a good response from five patients and the wives of two of these patients became pregnant soon after the last spermatogram was done.

Treatment of Asthenozoospermia with HCG

Andrologia, 2009
30 patients with isolated asthenozoospermia received a treatment with 5000 I.U. Human-Chorionic-Gonadotropin (HCG) a week intramuscularly for twelve weeks. Pretreatment basal levels of FSH, LH and testosterone were in normal or low normal range. 16 males responded to therapy, the total motility of spermatozoa increased significantly from 34% to 40%. In

LABORATORY METHODS FOR THE DIAGNOSIS OF ASTHENOZOOSPERMIA

Archives of Andrology, 2002
Human sperm samples from 46 men were evaluated for standard semen parameters by two trained technicians, according to WHO criteria. A computer-aided semen analyzer (CASA, HTM-IVOS) was employed. The overall mean coefficient of variation for the 2 participants and the 46 samples studied was 17% for the percentage of progressive motile spermatozoa (r = 0.

Relationship between ouabain and asthenozoospermia

Journal of Huazhong University of Science and Technology [Medical Sciences], 2014
A growing number of researches have shown that ouabain can regulate mammalian sperm function and male reproduction by modulating the sperm motility, capacitation and acrosome reaction in vitro. This study further examined the relationship between ouabain and asthenozoospermia.

NT-proCNP as a new indicator of asthenozoospermia

Advances in Medical Sciences, 2017
C-type natriuretic peptide (CNP) is a proinflammatory peptide. The highest concentration of CNP is found in male reproductive organs. This study aims to analyze the role of N-terminal C-type natriuretic propeptide (NT-proCNP) as a new indicator of asthenozoospermia.Semen was collected after 3-5 days of sexual abstinence from 86 men.

A novel splicing variant in DNAH8 causes asthenozoospermia

Journal of Assisted Reproduction and Genetics, 2021
To identify the genetic factors responsible for asthenozoospermia, which is a major cause of male infertility characterized by immotile and malformed spermatozoa.Whole-exome sequencing was performed in two brothers from a family with asthenozoospermia to identify pathogenic variants.

Asthenozoospermia/Teratozoospermia and Infertility

Archives of Andrology, 1990
Abnormal spermiograms with asthenozoospermia and teratozoospermia are often classified as subfertile, and the cause of these findings has been obscure. A new method, the 8-h in vitro motility profile test (MPT), showed a significant difference in motility profile between 130 fertile men and men of infertile couples.

Hyperprolactinemia in Men with Asthenozoospermia, Oligozoospermia, or Azoospermia

Archives of Andrology, 1997
The role of serum prolactin (PRL) in male infertility is still unclear. To assess the clinical significance of PRL determination during infertility studies, serum hormones and semen samples from 167 men attending the Andrology Clinic were analyzed, and PRL seric values were correlated with volume, sperm count, motility, viability, and morphology.

Electron microscopy in the investigation of asthenozoospermia

British Journal of Biomedical Science, 2010
Asthenozoospermia, defined as low sperm motility, is a significant cause of subfertility in men. Its origins are diverse and in some instances cannot be ascertained. However, severely reduced motility can often be associated with abnormalities in the structure of the sperm tails, which can only be detected by transmission electron microscopy (TEM).
