  • Patent number: 11904068
    Abstract: Disclosed are methods of delivering an agent to the lumen of the vas deferens under guidance of ultrasound imaging. The methods include vas-occlusive contraception in which the vas deferens is non-surgically isolated and an occlusive substance is percutaneously administered into the lumen of the vas deferens under ultrasound. Also disclosed are methods of reversal of vas-occlusive contraception and methods of delivering an agent to the lumen of the vas deferens. Also disclosed are compositions for use in the methods of the invention.

  • Publication number: 20230027709
    Abstract: The present invention provides compositions and methods useful for regulating fertilization and for use as a contraceptive based on the discovery herein of an oocyte specific protein, SAS1R (Sperm Acrosomal SLLP1 Receptor), which is a sperm protein receptor. Six SAS1R variants, including the full length SAS1R, were identified. mSLLP1 and SAS1R co-localized to oocytes and to acrosomes of acrosome-reacted sperm. Interactions between mSLLP1 and SAS1R were demonstrated by far-western analysis, in a yeast two-hybrid system under stringent selection conditions, and by immunoprecipitation of SAS1R by anti-mSLLP1 as well as the converse. Purified recombinant SAS1R was found to have protease activity, to inhibit fertilization in-vitro, and to induce an immune response in females.

  • Patent number: 7947026
    Abstract: A method and device to conform with the glans penis to recover ejaculated semen completely, to prevent the loss of initial sperm rich epididymal fractions, to avoid the use of a condom for masturbation, to eliminate the multi-step transfers of semen following ejaculation that are common with current methods, and to provide a single device that contains a semen collecting chamber that fits onto a glans penis. The device provides a storage and measuring reservoir, an optional cap, and a vertical stand in one integrally formed module in a sterile pack. The device and method will have multiple uses in a variety of contexts including, but not limited thereto: in the diagnosis of infertility, in semen donation, in vitro fertilization (IVF)/intra-cytoplasmic sperm injection (ICSI) clinics, hospitals, forensic laboratories and research laboratories and will be included in kits intended for over-the-counter sperm testing devices.
