摘要:
The present invention relates to a long acting biologically active luteinizing hormone (LH) compound comprising an LH agonist linked to a pharmaceutically acceptable molecule providing an in vivo plasma half-life of the LH agonist or LH compound which is increased substantially compared to the in vivo plasma half-life of an LH agonist administered in the same manner as the LH compound. The present invention relates to methods for controlled ovarian stimulation which can be used in conjunction with assisted reproduction technologies such as in vitro fertilization, intra cytoplasmatic sperm injection, intra uterine insemination and in vitro maturation. In other aspects the invention relates to methods for inducing folliculogenesis and methods for providing luteal support for the corpora lutea.
摘要:
The present invention relates to a method for in vitro maturation of oocytes comprising the steps of: (a) culturing one or more GV oocytes in a culture medium, the culture medium comprising a nuclear maturation inhibiting substance and comprising one or more gonadotropins and/or one or more growth factors, the culturing taking place for a time period sufficient for cytoplasmatic maturation to occur; (b) washing the GV oocytes of step (a) to remove the nuclear maturation inhibiting substance; (c) culturing the washed oocytes of step (b) in a culture medium comprising one or more gonadotropins and/or one or more growth factors and/or MAS for a time period sufficient for nuclear maturation. The invention also relates to an oocyte culture medium comprising a nuclear maturation inhibiting substance and comprising one or more gonadotropins and/or one or more growth factors. The nuclear maturation inhibiting substance may be a MAS antagonist or an FF-MAS synthesis inhibitor, preferably a cytochrome P450 lanosterol 14α-demethylase (P45014DM) inhibitor e.g. ketoconazole or 22-hydroxycholesterol. The one or more gonadotropins and/or one or more growth factors are preferably a combination of EGF and FSH and/or LH.The invention also relates to the use of a nuclear maturation inhibiting substance and one or more gonadotropins and/or one or more growth factors as described above for the preparation of a cell culture medium for in vitro maturation of oocytes.
