“…The human ovary is a dynamic organ which continually changes in size and activity through life, as an integral part of the hormonal changes in female through before, during and after her reproductive life 1 . Reproductive age, ovarian reserve, reproductive capability and prediction of response to induced ovulation or superovulationall these phenomena in modern reproductive medicine may be determined from measurement of the volume of the ovary 2, 3 .…”

“…However, whether this variation in ovarian size also reflects to the number of follicles is not known. Recently, it has been suggested in humans that the size of the ovary before IVF treatment can be used to predict outcomes of the treatment in term of the number of responded follicles and recovered oocytes [3]. These reports imply that a similar relationship between ovarian size and follicular population may also exist in cattle.…”

Abstract. The size of the ovary varies substantially among cattle. This variation may influence the potential of the ovary to produce follicles. In the present study, we examined whether a relationship exists between the weight of the ovary and the number of antral follicles ≥1 mm. Paired ovaries were obtained from Holstein × Japanese Black F1 heifers. Follicles were classified into three size categories (small: 1.0 -< 5.0 mm, medium: 5.0 -< 8.5 mm and large: ≥ 8.5 mm), and the number of follicles in each category was recorded. Large variations in the weight of ovaries and the number of follicles were observed among animals. Significant positive correlations (r≥0.4, P<0.001) were found between the weight of intact ovaries and the number of follicles in all three categories for the ovary contralateral to CL (OCC) and in the small follicles for the ovary ipsilateral to CL (OIC). Significant positive correlations (r>0.4, P<0.0001) were also observed between the weight of ovaries devoid of CL and follicles and the number of small and medium follicles in both OIC and OCC, indicating that the correlation is not due to the increase in ovarian weight associated with the increase in follicular number. Paired ovaries contained a similar number of small and medium follicles, and significant positive correlations were observed between them (r>0.6, P<0.0001). There were significant positive correlations between the weight of OCC and the number of small and medium follicles in paired ovaries (r>0.4, P<0.0001). These results suggest that 1) the weight of an ovary reflects the potential of the ovary to produce antral follicles, and 2) a rough estimation of follicular population might be possible by using the weight of the ovary contralateral to CL in heifers.

“…At birth, the ovary is approximately 1 cm in length as a flattened organ 2 . There is continuous slow growth of the ovaries throughout childhood, and at the time of puberty, they are in adult size 5 . After the menopause, the ovaries shrink to a size approximately one-half of that seen in the reproductive era.…”

“…A typical female cycle lasts 28 days; however, this can range from 21-35 days 1 . The ovarian cycle has two distinct phases: The follicular phase (days [1][2][3][4][5][6][7][8][9][10][11][12][13][14] and the luteal phase (days 14-28). The follicular phase is characterized by follicle development and growth, the goal being that one follicle matures and releases an egg at the time of ovulation, around day 14 of the female cycle.…”

SUMMARYObjective: Ovarian volume has a potential to be used in the indirect estimation of human ovarian reserve. The aim of this study was to determine ovarian volume measured during cesarean delivery at term pregnancy and to correlate the ovarian volume with maternal age and obstetric parameters. Method: Ovarian exploration was performed in women undergoing cesarean delivery. Each ovary was measured in three dimensions (height, width, and depth), and right and left ovarian volumes were determined using a simplified formula for a prolate ellipse. Results: Totally, 132 patients were found to be eligible for the study. Two-way ANOVA test (factors: Age groups and ovarian side) revealed significantly higher right ovarian volumes overall (p<0.05). However, we did not observe any significant interaction between side of the ovaries and the age groups (p>0.05). We also observed significant strong correlation between right and left ovarian volumes (r=0.69; p<0.05). There was no significant correlation between the right or left ovarian volumes and obstetric parameters (p>0.05). When we evaluated the left or right side separately, we found no significant difference in volumes among age groups (p>0.05). Conclusions: Cesarean delivery as an operation performed during reproductive period can be an opportunity to evaluate and to record the right and left ovarian volumes directly and correctly. Our findings support that during the time of delivery, the right ovarian volume is higher than left one. The information about the ovarian volumes may provide important information to solve future reproductive problems. In women with small sized ovaries, information about her ovarian reserve can be given before her discharge. Keywords: Ovarian volume, cesarean delivery, ovarian reserve ÖZET Amaç: Yumurtalık hacmi insanlarda yumurtalık rezervinin dolaylı olarak tahmin edilmesinde kullanılma potansiyeline sahiptir. Bu çalışmanın amacı term gebeliklerde sezaryen doğum esnasında ölçerek yumurtalık hacmini belirlemek ve yumurtalık hacmini anne yaşı ve obstetrik parametreler ile ilişkilendirmektedir. Yöntem: Sezaryen doğum sırasında yumurtalık gözlemi yapıldı. Her yumurtalığın üç boyutu (en, boy ve derinlik) ölçüldü ve basitleştirilmiş oval yapı formülü ile sağ ve sol yumurtalık hacimleri hesaplandı. Bulgular: Toplam olarak, 132 araştırmaya uygun hasta bulundu. İki-yönlü ANOVA testi (faktör-ler: Yaş grubu ve yumurtalık tarafı) genel olarak sağ yumurtalık hacminin daha büyük olduğunu gösterdi (p<0,05). Buna rağmen, yumurtalığın tarafı ile yaş grubu arasında anlamlı bir interaksiyon 43 CMJCumhuriyet Medical Journal bulunmadı (p>0,05). Aynı zamanda, Sağ ve sol yumurtalık hacimleri arasında önemli ve güçlü bir ilişki bulundu (r=0,69; p<0,05). Sağ veya sol yumurtalık hacimleri ve obstetrik parametreler arasında anlamlı ilişki bulunmadı (p>0,05). Sonuç: Sezaryen doğum üreme döneminde yapılan bir ameliyat olduğu için, sağ ve sol yumurtalık hacimlerinin doğrudan ve doğru bir şekilde değerlendirilmesi ve kayıt edilmesi için iyi bir fırsat olabilir.
