Problems solved by technology

But we know that the quality of many sperms is uneven. If the egg and many sperms are put together at the same time, it is very likely that a poor quality sperm will combine with the egg, thus making the quality of the offspring poor. Or directly affect the development rate of fertilized embryos and the success rate of embryo transfer

Embodiment Construction

[0018] Below in conjunction with the best embodiment shown in the accompanying drawings, it will be further described in detail.

[0019] Such as figure 1 As shown, the in vitro fertilization culture dish of the present invention includes a dish body 1; the two ends in the dish body 1 are provided with a first accommodating area 11 and a second accommodating area 12, the first accommodating area 11 and the second accommodating area 12 At least one groove 13 communicates with the second accommodating areas 12 .

[0020] The first accommodating area 11 , the second accommodating area 12 and the groove 13 are all surrounded by vertical walls extending upward from the bottom of the dish body 1 . Wherein, the first accommodating area 11 is relatively large and circular, and is used for placing eggs, and the second accommodating area 12 is relatively small, and has an oval shape, and is used for accommodating sperm.

[0021] Because the culture solution injected during the experim...

Abstract

The invention discloses an in vitro fertilization culture dish comprising a dish body (1); a first storage area (11) for storing ovum and a second storage area (12) for storing sperms arranged in the dish body (1), wherein the first storage area (11) and the second storage area (12) are communicated by at least a groove (13). Moreover the invention also discloses an vitro fertilization method using said culture dish. The in vitro fertilization culture dish and method of the invention can effectively guarantee only the high quality sperms with enough energy to go to the ovum and possibly combine with the ovum, thereby increasing the development rate of the fertilization embryo and the success rate of the embryo transplantation and finally guaranteeing the propagated progenies to have more excellent quality.

Description

technical field [0001] The invention relates to a device and a method used in reproductive medicine experiments, in particular to a vessel for in vitro fertilization and an in vitro fertilization method accomplished by using the vessel. Background technique [0002] In Vitro Fertilization (In Vitro Fertilization) or (external fertilization) refers to the technology in which mammalian sperm and eggs complete the fertilization process in an artificially controlled environment outside the body. It is referred to as IVF in English. Because it is inseparable from embryo transfer technology (ET), it is also referred to as IVF-ET. In biology, animals obtained by transplanting in vitro fertilized embryos into mothers are called test-tube animals. This technology was successfully developed in the 1950s, and has developed rapidly in the past 20 years. Now it has matured and become an important and conventional animal reproduction biotechnology. [0003] In vitro fertilization techno...
