  • Patent number: 6159159
    Abstract: A quantitative process for monitoring female fertility cycle wherein the process involves directing a laser beam, preferably generated by a diode laser, onto an area of a slide containing an air-dried sample of a female body fluid. The diffraction pattern resulting from the sample is detected by a two-dimensional photo diode array and analyzed by a microprocessor. If a ferning pattern exists, such pattern will generate a characteristic structure in the diffraction pattern which is then detected by the photo diode array. If no ferning occurs, the corresponding diffraction pattern will be structureless. The microprocessor is programmed with an algorithm to produce a quantitative index of ferning indicating quantitatively the ferning level. Preferably, a plurality of spots on the sample are measured to determine the ferning level at each spot, and the microprocessor then makes a final determination as to final ferning level on the basis of the test results of all of the spots.

  • Patent number: 5514537
    Abstract: A method and apparatus are disclosed for the mechanical sorting of mammalian spermatozoa by sex-type, into a fraction enriched in X-chromosome-bearing spermatozoa, and a fraction enriched in Y-chromosome-bearing spermatozoa. Because of their different DNA content, Y-chromosome spermatozoa are slightly smaller than X-chromosome spermatozoa. A column is packed with two sizes of beads. The size of the smaller beads is chosen such that, on average, Y-chromosome spermatozoa will readily fit into the interstices between the smaller beads, while X-chromosome spermatozoa, on average, will not readily fit into those interstices. The size of the larger beads is chosen such that the smaller beads will not readily fit into the interstices between the larger beads. A liquid sample containing the sperm is run through a column so that the liquid first encounters the larger beads, and then encounters the smaller beads.

  • Patent number: 5389519
    Abstract: A method for detecting the presence of infertility in mammalian male test subjects based upon failure of sperm to undergo successful capacitation. Sperm samples are given the opportunity to undergo capacitation and subsequently contacted with antibodies to polypeptides having an amino acid sequence tripeptide of Arginine-Glycine-Aspartate in their cell binding domains. Binding levels indicate the degree of capacitation and consequently the presence of infertility.

  • Patent number: 5250417
    Abstract: A method is provided for rapidly determining the ability of sperm to undergo the acrosome reaction, using fluorescence microscopy, light microscopy or color change on a dot blot assay to determine the relative percentage of acrosome reacted sperm. Sperm are capacitated through use of bromelain or other enzymatic substances capable of capacitating sperm, with the total incubation time required to induce capacitation as little as fifteen minutes, yielding sperm that are fully capacitated and show excellent motility, with as many as 80% of normal sperm consistently induced to acrosome react.

  • Patent number: 5155045
    Abstract: A novel method for treating a human female is disclosed comprising the step of exposing the nasal region of said female to at least a portion of the axillary secretions of a human male. This exposure is preferably continued in amounts and for a duration which are effective to significantly alter an endocrine related characteristic, such as the menstrual cycle length, of that female. In particular, the portions of male axillary secretions to be exposed to the female preferably comprise one or more compounds such as androstenol, dehydroepiandrosterone, and/or a compound or compounds exhibiting a burnt heavy axiallary-like odor which elutes at about 50 minutes as shown on the FID response curve of FIG. 3B. Studies show that pooled male donor secretions are effective to alter aberrant menstrual cycles, particularly those exhibiting luteal phase defects such that they become presumptively fertile menstrual cycles having durations of about 29.5.+-.3 days.

  • Patent number: 5118630
    Abstract: A natural birth control method comprises observance of the first day of menses followed by measurement of urinary progesterone metabolite levels beginning a predetermined number of days after the first day of menses. Urinary progesterone metabolite measurement is performed on days of planned sexual activity until the concentration level exceeds a threshold value indicative of ovulation occurring more than 24 hours previously. Once such a threshold value is observed, the woman may discontinue testing and can consider herself unable to conceive until after the beginning of the subsequent menstrual cycle.

  • Patent number: 5091170
    Abstract: The fertility of females, especially human females can be predicted by use of a clomiphene challenge test. The test is based upon comparison of follicle stimulating hormone and/or luteinizing hormone levels in urine or blood samples at two points in the menstrual cycle. The first test is performed on days 2-3 of the cycle. Clomiphene, and most preferably clomiphene in the form of clomiphene citrate, in a dosage of about 100 mg/day, is then administered, preferably on days 5-9. The second test is conducted on days 9-10. The test results are most conveniently compared by colorimetric methods involving monoclonal antibody reactions with follicle stimulating hormone and/or luteininizing hormone.

  • Patent number: 4999283
    Abstract: A method for separating male and female determining spermatozoa includes the initial step of exposing freshly ejaculated spermatozoa in a substantially protein free diluent to an excess concentration of a monoclonal antibody directed against H-Y antigen that binds substantially exclusively with male determining spermatozoa. The method continues with the suspending of the exposed spermatozoa together with a conjugate of (1) an immunoglobulin G antibody that binds substantially exclusively to the monoclonal antibody and (2) an immunoabsorbant substrate in a substantially protein free diluent. This forms a conjugate/spermatozoa preparation. The method concludes with the recovering of the separated male and female determining spermatozoa.
