Sperm morphology and reproductive success

Sperm morphology and reproductive success

fertilization potential, decisions on how to improve sperm morphology remain difficult to address. Smoking, alcohol consumption, caffeine intake and drug use can affect fertility; however, a conclusive connection between these factors and sperm morphology has not been demonstrated. Furthermore, use of dietary supplements and vitamins has not been shown to directly affect sperm morphology. While...

The Influence of Sperm Morphology, Total Motile Sperm Count of Semen and the Number of Motile Sperm Inseminated in Sperm Samples on the Success of Intrauterine Insemination

Sperm morphology, sperm motility and paternity success in the bluethroat (Luscinia svecica)

Postcopulatory sexual selection may select for male primary sexual characteristics like sperm morphology and sperm motility, through sperm competition or cryptic female choice. However, how such characteristics influence male fertilization success remains poorly understood. In this study, we investigate possible correlations between sperm characteristics and paternity success in the socially mo...

The Influence of Sperm Morphology, Total Motile Sperm Count of Semen and the Number of Motile Sperm Inseminated in Sperm Samples on the Success of Intrauterine Insemination

BACKGROUND The present study aimed to analyze the prognostic value of sperm morphology , total motile sperm count (TMSC) and the number of motile sperm inseminated (NMSI) on the outcome of intrauterine insemination (IUI). MATERIALS AND METHODS This cross sectional study was carried out 445 women undergoing 820 IUI cycles. All of the patients underwent controlled ovarian hyper stimulation with...

Sperm Vacuoles and Reproductive Outcome

It is estimated that the male factor contributes to half of the infertility in couples attending for assisted reproductive techniques (ART). Therefore the semen analysis remains the starting point to evaluate main causes of infertility and in case of oligospermic semen the assessment of sperm morphology may help to choose the best spermatozoon to use for the intracytoplasmic sperm injection (IC...
