Brief Summary

The object of this study is to determine the benefit of follicular flushing with a double channel needle in a poor responder population for a maximum number of oocytes to be retrieved. The investigators compare two methods of oocyte retrieval with or without flushing. 220 patients undergoing an in vitro fertilization (IVF) or Intracytoplasmic Sperm Injection (ICSI) have to be included. All patients with less than 5 follicles of 14 mm and more the day of ovulation induction will be included, following a randomized protocol in two groups, Group A: Oocyte retrieval is performed with a single lumen aspiration needle 17G. Group B: Oocyte retrieval is performed with a double lumen aspiration needle 17G. all follicles are flushed with flushing solution in addition to direct aspiration of the follicular fluid, 20CC of flushing medium is provided for all the procedure and flushing medium is collected separately from direct fluid aspiration in order to follow up each oocyte one by one. First criterion of our comparison is the number of oocyte retrieved. Second criteria are: oocyte quality, fertilization rate, number and quality of embryos obtained, clinical pregnancy rate. In Group B the investigators will compare two subgroups: oocytes collected in flush medium and oocytes from direct follicle fluid. Then the investigators will know the capability of oocyte collected after follicular flushing to be fertilized and to increase the success chance of pregnancy for poor responder patients.

Conditions

Infertility, Female; Ovarian Insufficiency

Outcome Measures

Primary Outcomes (2)

• the number of mature oocytes collected

  Increase the number of mature oocytes collected during the follicular flushing with a double lumen aspiration needle

  2 years and 9 months

• quality of embryos obtained

  Embryo quality is assessed at the Laboratory of Reproductive Biology by a score based on: cell number, cell regularity and degree of fragmentation.

  2 years and 9 months

Secondary Outcomes (3)

• Number of embryos obtained

  2 years and 9 months

• Number of transferable embryos (transferred and frozen)

  2 years and 9 months

• Number of pregnancies obtained

  2 years and 9 months
