Abstract: This disclosure provides a method for determining male fertility status. The method comprises determining GM1 distribution patterns following induced sperm capacitation, identifying the frequency of distribution of various patterns, and determining if the frequency distribution of certain GM1 patterns in response to induced capacitation is altered. Based on the change in the frequency distribution patterns of certain patterns in response to induced capacitation, alone or in combination with other sperm attributes, male fertility status can be identified.

Abstract: The present invention relates to methods of detecting a neural injury biomarker in a biological sample. The method includes subjecting a biological sample to an assay according to the present invention that produces a measurable signal and detecting the measurable signal. The presence or absence of the measurable signal indicates the presence or absence of the biomarker in the sample. The present invention also relates to methods of determining the state of a subject's neural injury. The present invention also relates to systems and devices useful in carrying out the methods of the present invention.

Abstract: This disclosure provides a method for determining male fertility status, and its relationship to the probability of generating a pregnancy as calculated using a regression model. The method comprises determining GM1 localization patterns following induced sperm capacitation, identifying the percentage of various patterns, particularly the ratio of [(AA+APM)/total number of GM1 localization patterns] and determining if the percentage of certain GMI localization patterns in response to induced capacitation is altered. Based on the change in the percentage of localization patterns of certain patterns in response to induced capacitation, alone or in combination with other sperm attributes, male fertility status can be identified.

Abstract: The diagnosis of male infertility is based predominantly on the results of standard semen analysis for concentration, total motility, progressive motility, volume, pH, viscosity and/or morphology. When sperm enter the female reproductive tract, they must undergo a series of physiological changes, known as capacitation, in order to fertilize an egg. This process involves plasma membrane changes that occur in response to stimuli within the female tract. These changes include removal of sterols and redistribution of the ganglioside GM1. Semen analysis identifies only half the cases of male infertility due to standard semen analysis providing little information on sperm functional competence. Previous data demonstrated that localization of the ganglioside, GM1, identifies sub-populations of sperm capable of undergoing the functional maturation process known as capacitation and tracks strongly with fertility.

Abstract: This invention describes unique patterns of distribution of ganglioside GM1 in non-capacitated sperm and demonstrates that the pattern of distribution of GM1 undergoes changes that can be correlated with the process of capacitation and/or with acrosomal exocytosis. Accordingly, the present invention discloses a method for determining the ability of sperm to respond to capacitation and/or acrosomal exocytosis stimuli. The method comprises determination of distribution pattern for GM1. The method can be used for both diagnostic and predictive purposes when assessing male reproductive fitness, and can also be used to assess the effects of any agent or environment on sperm including cryoprotective agents and protocols, and contraceptive agents.
