Abstract

The invention relates to the field of assisted reproduction, and discloses a composition for promoting sperm activation and a sperm activation solution. The sperm activation solution comprises a basicculture solution and a composition, wherein the composition comprises 2-10mg / L of ATP sodium salt, 5-15 U / mL of heparin, 5-10 [mu]g / mL of spot adhesion protein, 1-2.5[mu]g / mL of allene oxide synthase, 4-4.5 [mu]g / mL of acetyl coenzyme A acetyltransferase 2, 0.9-1.1 mmol / L of phosphatidylserine, 5.5-10.5 [mu]g / mL of coenzyme Q10, 3.5-6.5 ng / mL of linolenic acid and 0.45-0.5 [mu]g / mL of recombinantheat shock protein HSPA8. The invention also discloses a preparation method for the sperm activation solution. According to the sperm activation solution, the time of sperm injection and ovum in-vitro operation can be greatly shortened; the fertilization rate and the blastocyst formation rate are increased; the pregnancy rate is directly or indirectly increased; meanwhile, the sperm activation solution is effectively suitable for activation and optimization of sperms in an oocyte intracytoplasmic single sperm microinjection technology (ICSI) and an in-vitro fertilization (IVF) process in an in-vitro fertilization assisted reproduction technology.

Description

technical field [0001] The invention relates to the field of assisted reproduction, in particular to a composition for promoting sperm activation, a sperm activation liquid and a preparation method thereof. Background technique [0002] In vitro fertilization (in vitro fertilization, IVF), also known as test-tube baby, is a method of assisted reproductive therapy. Specifically, it refers to taking out eggs and sperm, performing in vitro fertilization, culturing and forming embryos, and then transferring the embryos back to the mother's uterus The inner pregnancy develops into a fetus. [0003] About 35-40% of infertile patients in assisted reproductive treatment cycles come from male factors, and the second-generation IVF is the main technology to solve male factor in vitro fertilization. The second-generation test-tube baby, also known as intracytoplasmic sperm injection (ICSI), in layman's terms, is to pick out a sperm with the strongest motility and the best quality unde...
