In vitro evaluation of sperm quality
This paper highlights selected laboratory analyses that are currently used to evaluate sperm, and describes why results from these assays do not consistently correlate with sperm fertility. Reasons for the disconnect between the two are due in part to the definition and reliability of the fertility data collected, to the complexity of the spermatozoon ...

The legacy of sperm banking: how fertility monitoring and disposal of sperm are linked with views of cancer treatment [PDF]
Background: sperm banking is recommended for all men before cancer treatment, which carries a risk of long-term gonadal damage. However, relatively few men take up the offer.

Computational Modelling of Sperm Behaviour in a 3D Virtual Oviduct [PDF]
The processes by which individual sperm cells navigate the length and complexity of the female reproductive tract and then reach and fertilise the oocyte are fascinating. Numerous complex processes potentially influence the movement of spermatozoa within

Cryopreservation of Pike Perch Sperm in Hatchery Conditions [PDF]
Experiments were carried out on pike perch (Sander lucioperca L.) to find a method for stripping sperm without contamination by urine, to determine sperm concentration, and to fertilize large batches of eggs with cryopreserved sperm.

Sperm mobility phenotype not determined by sperm quality index
We tested the capacity of the AviMate sperm quality analyzer to predict sperm mobility phenotype. A preliminary experiment was performed to determine a sperm concentration that afforded maximal sperm quality index (SQI) values with sperm from males with high sperm mobility.

The Role of Dietary Nutrients in Male Infertility: A Review
Male infertility is the main health issue with economic, psychological, and medical attributions. Moreover, it is characterized by an inability to produce a sufficient amount of sperm for the fertilization of an oocyte.
