Synthetic Semen Analysis Dataset (WHO 6th Edition) / 合成精液常规分析数据集

Dataset Summary / 数据集简介

A fully synthetic tabular dataset of 6,000 simulated routine semen analysis reports. Each record contains standard semen parameters and a diagnostic label derived from the lower reference limits of the WHO Laboratory Manual for the Examination and Processing of Human Semen, 6th edition (2021).

本数据集包含 6,000 条完全由程序模拟生成的精液常规分析记录，每条记录包含常规检测参数，并依据《WHO 人类精液检查与处理实验室手册（第六版，2021）》的参考值下限给出诊断标签。

⚠️ No real patient or donor data is included. All values are generated from parametric distributions with a fixed random seed. The dataset is intended for teaching, software testing, and ML prototyping — not for clinical use.

⚠️ 不含任何真实患者或供精者数据。 所有数值均由固定随机种子的参数分布生成，仅用于教学、软件测试和机器学习原型开发，不可用于临床诊断。

Intended Uses / 适用场景

  • Teaching WHO semen analysis reference values and nomenclature / 教学：WHO 参考值与诊断命名
  • Testing laboratory information systems (LIS) or sperm bank management software with realistic-looking data / 实验室信息系统、精子库管理系统的测试数据
  • Tabular classification baselines (multi-class diagnosis or binary is_normozoospermia) / 表格分类任务基线

Fields / 字段

Column Unit Description
sample_id – Synthetic ID (SYN-00001 …) / 合成样本编号
age_years years Simulated age / 年龄
abstinence_days days Days of abstinence (2–7) / 禁欲天数
volume_ml mL Semen volume / 精液体积
ph – pH
liquefaction_min min Liquefaction time / 液化时间
concentration_m_per_ml 10⁶/mL Sperm concentration / 精子浓度
total_count_m 10⁶ Total sperm number (volume × concentration) / 精子总数
progressive_motility_pct % Progressive motility (PR) / 前向运动
non_progressive_motility_pct % Non-progressive motility (NP) / 非前向运动
total_motility_pct % PR + NP / 总活力
immotile_pct % Immotile (IM) / 不动
vitality_pct % Live spermatozoa / 存活率
normal_morphology_pct % Normal forms / 正常形态率
leukocytes_m_per_ml 10⁶/mL Peroxidase-positive leukocytes / 白细胞
diagnosis – WHO-based diagnostic label / 诊断标签
is_normozoospermia 0/1 Binary label / 二分类标签

For azoospermia samples, motility, vitality and morphology are null (not assessable). 无精子症样本的活力、存活率和形态字段为空值（无法评估）。

Labeling Rules / 标签规则

Lower reference limits (WHO 2021, 5th percentile) used for classification:

Parameter Lower reference limit
Volume 1.4 mL
Concentration 16 × 10⁶/mL
Total sperm number 39 × 10⁶
Progressive motility 30 %
Total motility 42 %
Vitality 54 %
Normal morphology 4 %

Label logic: concentration = 0 → azoospermia; < 1 × 10⁶/mL → cryptozoospermia; otherwise sub-threshold concentration/total count, progressive motility and morphology are combined as oligo-, astheno-, terato-zoospermia; volume < 1.4 mL adds hypospermia, leukocytes > 1 × 10⁶/mL adds leukocytospermia. All parameters at or above limits → normozoospermia.

Label Distribution (full set) / 标签分布

diagnosis count
normozoospermia 2,658
oligozoospermia 664
teratozoospermia 661
asthenozoospermia 607
oligo-astheno-teratozoospermia 412
cryptozoospermia 175
azoospermia 157
leukocytospermia 157
hypospermia 154
other combinations 355

Generation Process / 生成方法

Records are drawn from a mixture of simulated clinical profiles (normal, oligo, astheno, terato, OAT, hypospermia, cryptozoospermia, azoospermia, leukocytospermia), with log-normal / normal distributions and a mild positive effect of abstinence on volume and concentration. Labels are then computed deterministically from the generated values. See generate.py (seed = 42) to reproduce or regenerate with different parameters.

数据由多种模拟临床表型混合生成，采用对数正态/正态分布，并加入禁欲天数对体积和浓度的轻度正向影响；标签由生成的数值按规则确定性计算。运行 generate.py（seed=42）可完全复现。

Limitations / 局限性

  • Distributions are plausible but not fitted to any real population; correlations between parameters are simplified.

  • Label prevalence does not reflect any real clinic or population.

  • Because labels are rule-based, a model can achieve near-perfect accuracy — useful for pipeline testing, not as evidence of clinical predictive value.

  • 分布形态合理，但未拟合任何真实人群；参数间相关性做了简化。

  • 各类别比例不代表真实临床或人群患病率。

  • 标签由规则计算，模型可轻易达到接近完美的准确率，适合测试流程，不代表临床预测价值。
