In-Vitro Maturation of Oocytes From Polycystic Ovarian Patients Undergoing IVF (IVM)

Last verified: March 2010
Retrieval of immature oocytes from women with polycystic ovaries, their in-vitro maturation, fertilization and embryo transfer can prevent hormonal treatment that can lead to ovarian hyperstimulation. In addition, it can decrease discomfort and side-effects of routine daily administration of hormones and it can be cost-effective. Thirty healthy women with Polycystic Ovarian Syndrome aged 20-35, with BMI 18-30 kg/msq will be included in the study. Their immature oocytes will be retrieved from small follicles without any hormonal treatment. The oocytes will be fertilized post in-vitro maturation. The developed embryros will be transferred to the patients as in a routine IVF cycle.

Further study details as provided by Hillel Yaffe Medical Center:

Primary Outcome Measures:
  • Maturation rate of oocytes, their fertilization rate, cleavage rate and embryo quality. [ Time Frame: one year ]

Secondary Outcome Measures:
  • Implantation rate and successful delivery. [ Time Frame: one year ]

Enrollment: 30
Study Start Date: January 2008
Study Completion Date: January 2009
Arms Assigned Interventions
Experimental: Observational Other: In-vitro maturation oocytes
Immature oocytes (development stage GV or M1) will be matured in-vitro in IVM culture medium for approximately 28-32 hours. The oocytes will be routinely observed and when they reach maturation (M2) they will be fertilized. The developed embryo will be transferred to the patient 24 hours post-fertilization.
