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...
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...
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...
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 ...
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...
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 ...
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)...
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...
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...
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 ...
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.
