Methods for non-invasive retrieval of viable (i.e., able to be fertilized) oocytes from the uterus via a combination of unique ovarian stimulation and uterine lavage technology. These methods may eliminate the need for an invasive surgical procedure. Embodiments include the use of a novel hormonal protocol, including the use of injectable gonadotropins, to induce the release of immature oocytes from the ovaries of a patient. The immature oocytes mature as they transit the fallopian tubes such that mature, viable oocytes may be collected from the uterus via a uterine lavage procedure. Further embodiments include the use of a novel hormonal protocol, including the administration of Prostaglandins, Estradiol, and/or Progesterone Blockers, to accelerate transport of oocytes through the fallopian tubes. Further embodiments include kits for uterine lavage, compositions suitable for triggering and inducing superovulation, and compositions suitable for accelerating tubal transport of mature oocytes in a female patient.

Provided is a novel means of inhibiting fertilized egg fragmentation. The present invention provides an inhibitor of fertilized egg fragmentation, said inhibitor comprising selenoneine or ergothioneine, a tautomer or dimer thereof, or a pharmaceutically acceptable salt of the same as an active agent.

The invention provides a method for culturing mammalian cells. The method provides greater control over cell growth to achieve high product titer cell cultures.

The present disclosure relates to using CRISPR-based methods to perform gene editing to correct frame shift mutations in alleles with detectable phenotypes, and to correct aneuploidies.

Disclosed herein are chimeric blastocysts, such as chimeric blastocysts derived from a host blastocyst from a first mammalian species and having donor pluripotent stem cells from a second mammalian species, wherein the donor pluripotent stem cells have reduced expression or reduced biological activity of one or more proteins in the TLR/NF-kB signaling pathway or the p53 pathway. Methods of preparing chimeric blastocysts and methods of obtaining mammalian organs and tissues are also provided.

The method for automated cell positioning can include: sampling a video of a scene having a gamete, tracking the gamete, and positioning the gamete within a target region. The method can optionally include: determining attribute values for the gamete, selecting the gamete, reorienting the gamete, and/or manipulating the gamete, and/or any suitable steps.

System, method and computer readable medium that assess characteristics of an embryo by processing video image data of the embryo. Video is obtained, typically from third parties, of a target embryo. The video has frame speed of two frames per second, or faster and includes image data representing morphokinetic movement of the embryo. The image data is processed using a trained machine learning model that assesses embryo characteristics. The video has a duration of ten minutes or less. The assessment can be a prediction of a likelihood the embryo is viable and/or will produce a pregnancy upon transfer into a recipient. Further, the assessment can predict a likelihood the embryo will: (1) produce offspring having a specific sex; (2) embody a genetic anomaly; (3) perpetuate desired traits in produced offspring and/or (4) produce undesired characteristics in produced offspring.

A computer-implemented system and method for predicting male sex bovine offspring to result from a bovine embryo by processing video image data of the embryo. The method includes receiving image data derived from video of a target embryo taken at substantially real-time frame speed during an embryo observation period of time. The video contains recorded morphokinetic movement of the target embryo occurring during the embryo observation period of time. The movement is represented in the received image data and the received image data is processed using a model generated utilizing machine learning and correlated embryo outcome data.

An object of the present invention is to provide a method for cryopreserving rat sperms and an in vitro fertilization method using cryopreserved rat sperms. The present invention provides a method for preparing cryopreserved rat sperms, characterized by comprising the following steps: step a: a preparation step of collecting rat sperms from the rat cauda epididymis to prepare a sperm suspension, step b: a cooling step of cooling the sperm suspension to about 1° C. or lower, and step c: a freezing step of freezing the rat sperm suspension cooled to about 1° C. or lower.

The present invention relates to improved assisted reproductive technology using highly purified menotropin (HP-hMG) to stimulate follicle development in controlled ovarian stimulation, particularly in women at risk of a high ovarian response to controlled ovarian stimulation.
