Abstract

Context and rationale: The age related infertility due to early ovarian ageing is one of the problems for women who want to become pregnant in late age in our country. Ovarian ageing reflects in its morphology. So this study was aimed at determining the gross morphology of the ovary in different age groups of Bangladeshi female (cadaver) to assess the possible relationships among different morphological variable of ovaries in different age groups. The present study would serve as a baseline data for the gynecologist, obstetricians and endocrinologist about the onset of infertility in the context of Bangladesh. Materials and methods: Cross sectional analytical type of study was conducted at the department of Anatomy, Rangpur Medical College, Rangpur. Fifty pairs postmortem human ovaries from Bangladeshi female aged between 15 and 45 years were examined for morphological study. The morphological parameters such as length, breadth, circumference, weight and volume of the right and left ovaries determined by physical method and the data were compared between different age groups. Result: Mean length, circumference and volume were significantly higher in group A than the other groups in both right and left sides. The difference reached a significant level (P< 0.05) in both ovaries in between and within groups for all mentioned parameter. The mean breadth of right ovary in group B and mean breadth of left ovary in group A were larger than the other groups but was not significant. Conclusion: The values of the morphological measurements fall from younger to older women. This may be due to depletion of the ovarian non-growing follicles thus reflecting fall in the ovarian reserve.

卵巢形态作为生殖年龄决定因素的研究
背景与理由:卵巢早衰导致的年龄相关性不孕是我国高龄怀孕妇女面临的问题之一。卵巢衰老表现在形态上。因此,本研究旨在测定孟加拉女性(尸体)卵巢不同年龄组的大体形态,以评估不同年龄组卵巢不同形态变量之间可能存在的关系。本研究将作为孟加拉国妇科医生、产科医生和内分泌学家关于不孕症发病的基线数据。材料和方法:横断面分析型研究在Rangpur医学院解剖系进行。对50对年龄在15 - 45岁之间的孟加拉女性死后卵巢进行形态学研究。采用物理方法测定左右卵巢的长、宽、围、重、体积等形态学参数,并对不同年龄组的数据进行比较。结果:A组左右两侧的平均长度、周长和体积均显著高于其他两组。各组间和组内双卵巢各项指标差异均达到显著水平(P< 0.05)。B组右卵巢平均宽度和A组左卵巢平均宽度均大于其他各组,但差异不显著。结论:形态学测量值从年轻到老年呈下降趋势。这可能是由于卵巢非生长卵泡的消耗,从而反映了卵巢储备的下降。DOI: http://dx.doi.org/10.3329/bja.v11i2.20675孟加拉解剖学杂志,2013年7月,Vol. 11 No. 2 pp 77-80
