Last verified: October 2009
History: No changes posted
The aim of this study is to compare whether oocyte flushing during retrieval is effective or not.

Condition Intervention
Oocyte Retrieval
Device: single lumen needle oocyte retrieval
Device: double lumen needle oocyte retrieval

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Participant)
Official Title: Single Lumen Needle Without Flushing or Double Lumen Needle With Follicle Flushing in Oocyte Retrieval

Further study details as provided by Baskent University:

Primary Outcome Measures:
  • Metaphase 2 oocyte number [ Time Frame: 6months ]

Secondary Outcome Measures:
  • clinical pregnancy rate [ Time Frame: 6 months ]

Enrollment: 400
Study Start Date: March 2008
Study Completion Date: November 2008
Primary Completion Date: September 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
Single lumen needle use in oocyte retrieval
Device: single lumen needle oocyte retrieval
single lumen needle use during oocyte retrieval
Active Comparator: 2
Double lumen needle with follicle flushing during oocyte retrieval
Device: double lumen needle oocyte retrieval
double lumen needle with 1 time follicle flushing with at least 2 ml during oocyte retrieval

Detailed Description:
In total 300 patients will be randomized for the effectiveness of single or double lumen needle during oocyte retrieval. Double lumen needles give an opportunity of washing to the follicle with flush. Single lumen needles seem to be faster and no need for flushing. We aim to compare to the differences of the use of both needles.
