Abstract

Developing a culture system for preantral follicles has important biotechnological implications due to the
potential to produce a large number of oocytes for embryo production and transfer. To accomplish this goal,
the present study was aimed to culture preantral follicles in the presence of different media, sera and FSH
concentrations. Six-week-old preantral follicles (95 ± 5 µm) were cultured in North Carolina State University
medium 23 (NCSU23), tissue culture medium 199 (TCM199) and leibovitz-15 medium (L-15) for 6 days.
Tissue culture medium 199 showed a significant increase inthe follicle diameter (115 µm), survival (39%),
oocyte maturation (32%) and germinal vesicle breakdown (GVBD) (29%) rates as compared to L-15 and
NCSU23 (P(P(PGS), embryonic stem cell fetal calf serum (ESFCS) and hypogonadal mouse serum (hpgMS), the 5% FCS showed increased follicle diameter (134 µm), survival (52%), oocyte maturation (49%) and GVBD (45%) as compared to control and other types of sera used (Pshowed a significant increase in follicle diameter (197 µm), survival (96%), oocyte maturation (91%) and GVBD (67%: PFSH and 5% FCS, is appropriate for the optimal in vitrogrowth of Syrian mice preantral follicles and enclosed oocytes.
