The aim of this study is to study the effect of peginterferon alpha and ribavirin on spermatozoa.
During and six months after treatment with peginterferon alpha and ribavirin strict use of birth control is recommended (the producers advice two reliable forms) for both men and women because ribavirin has teratogenic and/or embryo-lethal effects in animal studies.
In cases of pregnancies during paternal exposure to peginterferon alpha and ribavirin elective termination of the pregnancy is usually recommended. However three cases of births after paternal exposure are reported with no birth defects. Cases of abnormalities after paternal exposure to ribavirin are lacking.
Also studies on the influence of ribavirin on sperm in human are lacking.
The aim of this study is to study the effect of peginterferon alpha and ribavirin on spermatozoa in men using these medication.

The primary purpose of the study is to compare the safety and effectiveness of standard treatment for chronic hepatitis C using peginterferon alpha-2a (Pegasys) and ribavirin (Copegus) to ...
The objective of this study is to evaluate the efficacy of three regimens of peginterferon-alfa 2b either as monotherapy or in combination with ribavirin in patients with acute hepatitis C...
Based on previous experience with peginterferon alfa-2b/ribavirin in combination with boceprevir, the combination with peginterferon alfa-2a/ribavirin and boceprevir is expected to be safe...
The purpose of this study is to determine if the use of epoetin-alpha will allow patients with chronic hepatitis C virus infection to be treated with higher doses of peginterferon-alpha-2b...
The purpose of this study is to identify one or more doses of BMS-650032 that, when used in combination with pegylated-interferon alpha and ribavirin are safe and demonstrate sufficient ac...
Membrane integrity is essential in maintaining sperm viability, signaling, and motility, which are essential for fertilization. Sperm are highly susceptible to oxidative stress, as they are rich in se...
Motility is an essential function of the mature male gamete and is widely used as an indicator of semen quality. Knowledge of signal transduction pathways regulating sperm motility is therefore import...
Increasing studies have shown that specific mRNAs and miRNAs expressed in mature sperm may be related to sperm motility. However, the expression profiles and roles of lncRNAs in sperm remain unknown. ...
Motility of spermatozoa is crucial factor for determining semen quality. Here we report Motility inhibitory factor (MIF-II) from goat epididymal plasma, revealing its structure, function, localization...
Sperm motility is one of the most important indicators for evaluating roosters' fecundity. However, molecular regulation underlying chickens' sperm motility remains to be understood. MicroRNA (miRNA) ...
The quality of SEMEN, an indicator of male fertility, can be determined by semen volume, pH, sperm concentration (SPERM COUNT), total sperm number, sperm viability, sperm vigor (SPERM MOTILITY), normal sperm morphology, ACROSOME integrity, and the concentration of WHITE BLOOD CELLS.
An assisted fertilization technique consisting of the microinjection of a single viable sperm into an extracted ovum. It is used principally to overcome low sperm count, low sperm motility, inability of sperm to penetrate the egg, or other conditions related to male infertility (INFERTILITY, MALE).
The posterior filiform portion of the spermatozoon (SPERMATOZOA) that provides sperm motility.
The structural and functional changes by which SPERMATOZOA become capable of oocyte FERTILIZATION. It normally requires exposing the sperm to the female genital tract for a period of time to bring about increased SPERM MOTILITY and the ACROSOME REACTION before fertilization in the FALLOPIAN TUBES can take place.
The maturing process of SPERMATOZOA after leaving the testicular SEMINIFEROUS TUBULES. Maturation in SPERM MOTILITY and FERTILITY takes place in the EPIDIDYMIS as the sperm migrate from caput epididymis to cauda epididymis.
