Impact of Escitalopram on Sperm DNA Fragmentation

Double-blind placebo-controlled randomized trial of daily escitalopram for 6 weeks in healthy men with normal semen analyses and no psychiatric history of depression, bipolar, mania or sui...

Effects of Procyanidine on Semen Parameters and DNA Fragmentation Index During Cryopreservation of Abnormal Human Semen Samples

Cryopreservation is the storage of biological material at subzero temperatures at which biochemical processes of cell metabolism and the biochemical reactions that lead to cell death are s...

Semen Analysis After Proton Therapy for Prostate Cancer

The purpose of this study is to evaluate semen for changes following radiation treatment with proton beam radiotherapy alone. The semen samples will be compared for sperm count, sperm move...

Impact of Sperm Oxidative Stress on Embryonic Parameters and Pregnancy Success During Intrauterine Insemination and in Vitro Fertilization

Oxidative stress (OS) is characterized by an imbalance between the production of reactive oxygen species (ROS) and the ability of the body to eliminate them. Such an imbalance can lead to ...

Impact of DNA Fragmentation in Sperm on Pregnancy Outcome After Intra-uterine Insemination in a Spontaneous Cycle

Infertility affects about 10% of all couples and is defined by a failure to achieve a clinical pregnancy within a year of regular unprotected sexual intercourse. Up to one third of these c...

Methotrexate Reduces DNA Integrity in Sperm From Men with Inflammatory Bowel Disease.

There are few data on the effects of methotrexate on reproductive capacity in men with inflammatory bowel diseases (IBD). We performed a case-control study to determine the effects of methotrexate on ...

Correlation between objective semen analysis and fertility in Japanese quail.

This study investigated the relationship between sperm kinematics and egg fertility in Japanese quail in an attempt to identify a semen trait that could be used to predict male fertility. Males (n=45)...

Comparative analysis of human sperm glycocalyx from different freezability ejaculates by lectin microarray and identification of ABA as sperm freezability biomarker.

Semen cryopreservation has been widely applied in assisted reproductive technologies and sperm bank, but it causes considerable impairments on sperm quality. It is necessary to find an evaluation indi...

Comparison of semen samples collected from wild and captive jaguars (Panthera onca) by urethral catheterization after pharmacological induction.

This study was designed to evaluate the efficiency of medetomidine anesthesia for semen collection through urethral catheter in wild and captive jaguars. Six captive and five wild jaguars were chemica...

Variables affecting semen quality and its relation to fertility in the dog: A retrospective study.

Although semen analysis is routinely used to evaluate the male reproductive potential in the canine species, only a few authors have attempted to relate semen characteristics to donor traits, such as ...

Medical and Biotech [MESH] Definitions

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.

A condition characterized by the complete absence of SEMEN. This disorder should be differentiated from AZOOSPERMIA, absence of sperm in the semen.

A condition of suboptimal concentration of SPERMATOZOA in the ejaculated SEMEN to ensure successful FERTILIZATION of an OVUM. In humans, oligospermia is defined as a sperm count below 20 million per milliliter semen.

A multistage process that includes the determination of a sequence (protein, carbohydrate, etc.), its fragmentation and analysis, and the interpretation of the resulting sequence information.

Centers for acquiring and storing semen.
