OBJECTIVES Male infertility is on the rise. Artificial insemination is an option in many cases like oligozoospermia or oligoasthenozoospermia. Homologous insemination is helpful for some couples in whom sperm count is low. This study was aimed to understand the most suitable portion of split ejaculate for insemination and also the level of calcium and magnesium in each split. MATERIALS AND ME...
Human ejaculates contain extracellular vesicles (EVs), that to a large extent are considered to originate from the prostate gland, and are often denominated "prostasomes." These EVs are important for human fertility, for example by promoting sperm motility and by inducing immune tolerance of the female immune system to the spermatozoa. So far, the EVs present in human ejaculate have not been st...
It is thought that differences in conception rate between feline epididymal sperm and ejaculate sperm occur because, unlike ejaculated sperm, caudal epididymal sperm have not been sensitized with seminal plasma (SP). In this study, we investigated whether collection of feline epididymal sperm with SP influences sperm qualities after freezing-thawing. Sperm were sensitized with SP for 10 min at ...
Furazolidone was given to male Nubian goats for 5 days at a therapeutic dose of 10 mg/kg or at a dose of 40 mg/kg, and the effect on semen morphology and biochemistry was studied. At the lower dose, furazolidone significantly reduced seminal ejaculate volume, the number of motile spermatozoa per ejaculate and the number of live spermatozoa per ejaculate, while secondary abnormalities increased....
Though others may have found this question hard to swallow (ba-dum-tcchh!), having the strength to be open about this is admirable. Finding yourself with a case of the runs can certainly put a damper on your whole sexual experience. While a semen allergy is one possible cause of dicey bowels, such allergies are quite rare. Perhaps you?ll be relieved to hear that it?s more likely that your diarr...
Objective: The objective of this study was to determine the effect collection method and number sequential ejaculates on beef bull ejaculate characteristics.
OBJECTIVE To compare equine synovial fluid (SF) from injured and control joints for cartilage boundary lubrication function; concentrations of the putative boundary lubricant molecules hyaluronan (HA), proteoglycan 4 (PRG4), and surface-active phospholipids (SAPLs); relationships between lubrication function and composition; and lubrication restoration by addition of HA. METHODS Equine SF fro...
The experimental material consisted of 75 ejaculates collected form 8 Duroc boars. The ejaculates were divided into three groups according to sperm concentration in an ejaculate. An ejaculate was obtained from each boar monthly and it was used to make microscopic preparations to examine spermatozoa morphology. In each preparation morphometric measurements were taken of fifteen randomly selected...
Homocysteine, glutathione and related thiols affect fertility parameters in the (sub)fertile couple.
BACKGROUND Thiols are scavengers of reactive oxygen species (ROS). We aim to investigate associations between thiols in various fluids in (sub)fertile couples and fertility outcome parameters. METHODS In 156 couples undergoing assisted reproduction techniques (ART), we measured the concentrations of glutathione (GSH), cysteine (Cys), homocysteine (Hcy) and cysteinylglycine (CGS) and fertility...
Shortening age at puberty of crossbred breeding bull is an important issue in the tropics. This study aimed at selecting crossbred bulls at earliest possible age with bigger scrotum and potential for donating quality semen. One hundred and 31 pre-joining crossbred bulls of Central Artificial Insemination Laboratory, Saver, Dhaka were examined. The bulls being trained by seeing semen collection ...
