We describe a method for interrogating the content and primary structure of DNA by microarray analyses and to provide comprehensive genetic screening and diagnostics prior to embryo transfer within an IVF setting. We will accomplish this by the following claims: 1) an optimized embryo grading system, 2) a less invasive embryo biopsy with reduced cellular contamination, 3) an optimized DNA amplification protocol for single cells, 4) identify aneuploidy and structural chromosome abnormalities using microarrays, 5) identifying sub-telomeric chromosome rearrangements, 6) a modified DNA fingerprinting protocol, 7) determine imprinting and epigenetic changes in developing embryos, 8) performing genome-wide scans to clarify/diagnose multi-factorial genetic disease and to determine genotype/haplotype patterns that may predict future disease, 9) determining single gene disorders with or without a known DNA mutation, 10) determining mtDNA mutations and/or the combination of mtDNA and genomic (nuclear) DNA aberrations that cause genetic disease.

An intravaginal fertilization and culture container includes a main chamber and a microchamber. A culture medium, one or more oocytes and sperm are introduced through an access opening having an associated resealable closure device. The container is enveloped in a capsule of soft elastic material prior to lodgment in the posterior fornix. A loop on one capsule part adapts the length to anatomic variations. The microchamber has a channel which receives the catheter tip to facilitate embryo retrieval while eliminating risk of injury thereto. The microchamber permits embryos to be microscopically inspected in situ before transfer to the uterine cavity.

An embryo-transfer catheter has an extruded shaft with a gas-filled lumen that extends helically along the catheter to provide an ultrasound marker. The catheter has a side opening close to a closed rounded patient end. The catheter could be completely transparent to x-rays or the plastics from which it is formed could incorporate an x-ray opaque filler, such as barium sulphate.

The invention relates to an apparatus and a method useful for non-surgical embryo transfer or artifical insemination of mammals. An apparatus for depositing media into the uterus of a mammal includes a conical chamber that has a plurality of perforations and flaps. An exterior spiral formation is configured for traversing or penetrating cervical passageway. A sheath having a frusto-conical rearward end extends axially from an aft end of the conical chamber. A tubular depositing chamber extends axially from the conical chamber to a position beyond a fore end of the conical chamber. Coupled to the rearward end of the depositing chamber is an embryo or semen packaging unit. The tubular depositing chamber has an end that has an aperture to permit the flow of semen out of the depositing chamber and into the uterus. The invention also involves a method for depositing of embryos or semen into a uterus of a mammal by a) inserting a conical chamber having a fore end and an exterior spiral formation into a cervix of a mammal, b) securing the conical chamber with the walls of the cervix, c) projecting a depositing chamber through an interior portion of the conical chamber, d) moving the depositing chamber to an embryo or semen release position for release of embryos or semen in the uterus, and e) securing an embryo or semen packaging unit to the depositing chamber to deposit embryos or semen in the uterus.

Crystalline (3Z,5S)-5-(hydroxymethyl)-1-[(2′-methyl-1,1-biphenyl-4-yl) carbonyl]pyrrolidin-3-one O-methyloxime is disclosed. A pharmaceutical composition containing the crystalline compound and methods for treating conditions related to the OT-R activity, such as preterm labor, and tor increasing embryo implantation rate in a mammal undergoing embryo transfer, comprising administering the crystalline compound are also disclosed.

An embryo transfer catheter with a protective sheath is disclosed. The use of a protective sheath shields a guide catheter from cervical mucus. The retracted open flaps of the outer protective sheath draw the mucus and blood away from the inner guide catheter. This allows an inner embryo transfer sheath to enter the uterus unobstructed. The embryo is then transferred to the uterus by means of fluid pressure with a culture medium. The protective sheath may be snap fit onto the guide catheter. The sheaths and catheters may be manufactured in a variety of lengths for individual convenience and then snap-fit onto each other for better control during an embryo implantation procedure. Other catheters and related instruments may also be manufactured with snap-on features.

Instead of immersing human reproductive cells in a single culture medium throughout the various procedures used in IVF, a process is provided by which the reproductive cells may be moved through a sequence of distinct culture media as the various IVF procedures are carried out. In one implementation, the culture media specifically formulated to provide a physical environment similar to that found within the female reproductive tract and conducive to growth and development of human reproductive cells during the various stages of the IVF process. In this regard, specifically formulated culture media can be applied to support the reproductive cells in one or more of the following procedures: oocyte retrieval and handling; oocyte maturation; ordinary fertilization; oocyte, zygote and embryo examination and biopsy; embryonic development to the eight-cell stage; embryonic development to the blastocyst stage; embryo transfer; and cryopreservation.

An embryo transfer catheter or other medical device has a shaft extruded with two layers. The outer layer is relatively thick and contains gas bubbles sufficient to increase the visibility of the catheter under ultrasound observation but with a density that allows material within the catheter to be viewed by the eye. The inner layer is relatively thin and is free of bubbles so that it provides a smooth bore to the catheter.

The present invention relates to the use of an oxytocin receptor antagonist in females undergoing embryo transfer as part of an assisted reproductive technology. In particular, methods are provided for increasing ongoing implantation rate, increasing ongoing pregnancy rate, increasing clinical pregnancy rate, and/or increasing live birth rate in a female subject undergoing embryo transfer. Specifically, the antagonists are released in the luteal phase when the endometrium is receptive for embryo implantation and/or when the embryo has reached the blastocyst-stage.
