Clinical Study of Recombinant Human Follitropin for Injection Assisted in COH Assisted IVF-ET

The aim of this study was to evaluate the efficacy and safety of domestic recombinant human follicle stimulating hormone (rhFSH) stimulating ovarian to promote follicular development before assisted reproductive technology, which was non-inferiority than that of the imported rhFSH.


Eligibility Criteria:
Inclusion Criteria:

* Age is more than 20 years old and less than 39 years old, married.

* 18kg/m2≤BMI\<30kg/m2.
* The level of basic serum FSH \<10IU / L in the 2nd-5th days of the menstrual cycle, the luteinizing hormone, estradiol and progesterone levels were normal.
* The screening period or recent three months of vaginal ultrasound examination showed that the shape of bilateral ovarian and uterine size were normal and 5 ≤ number of basal antral follicle in unilateral ovarian \<10, and follicular diameter \<10 mm.
* The in vitro fertilization and embryo transfer (IVF/ET) and (or) intracytoplasmic sperm injection (ICSI) technology were less than three times used prior to the reproductive treatment (provide copies of previous cases).
* Volunteer to participate and sign informed consent.
