"The male who ejaculates the greatest number of sperm may win at this game, and hence many bats have evolved outrageously big testes," Pitnick said.

Pitnick认为：睾丸能射出最多精子数量的雄性蝙蝠在交配中才有可能胜出，因而许多蝙蝠通过进化，都有了超常大的睾丸。

ResultsDuring the whole experimental period, testes and epididymides weight of high dose group was significantly different from the control group.

结论Mahoganoid蛋白及其mRNA在成熟大鼠睾丸和附睾组织中均有表达，二者分布基本一致，提示Mahoganoid在精子发生中可能具有一定的作用，并且睾丸和附睾具有自主合成Mahoganoid蛋白的能力。

Aging influences spermatogenesis in testes and sperm maturation in epididymides.

Methods: The levels of serum sex hormones in diabetic rats, normal rats and streptozotocin rats were detected by radioimmunoassay and their sexual glands were collected and weighed and the histomorphology of testes, prostate glands and epididymides was observed under a microscope.

Each male ratwas paired with 2 female rats in proestrus when administration terminated. Femalerats were examined the next morning for the presence of sperm in vaginal smears andunderwent a cesarean section on day 13 of gestation. Then the reproductive indiceswere calculated as follows: copulation index, pregnancy index, and fertility index,which can evaluate male fertility directly. The sperm motility and morphology wereevaluated by computer-assisted sperm analysis, moreover, the caudaepididymal sperm ultramicrostructure were analyzed by transmission electronmicroscope, which can evaluate the influence on sperm maturation bydutasteride ; sperm survival rate was assessed by SYBR-14 and propidium iodidefluorescent staining; serumal dihydrotestosterone and testosterone of ratswere detected by enzyme-labeled immunoassay, which can evaluate the effecton androgenic levels; the weights of testes and epididymides, were determined byprecise electronic balance; histological examination of above tissues were evaluatedby HE staining and TEM, which can evaluate treatment on histology of reproductiveorgans by dutasteride.

给药结束后雄鼠与处于动情前期的雌鼠按2：1合笼，计算雌鼠的交配指数、受孕指数和生育指数，直接评价雄鼠生育力；采用计算机辅助精子分析系统分析大鼠附睾精子活力和形态，在此基础上合并使用透射电镜技术对各组附睾尾部精子进行透射电镜分析，评价度他雄胺对大鼠精子成熟的影响；采用SYBR-14和propidium iodide双重荧光染色计算精子存活率；采用Elisa法测定大鼠睾酮(testosterone， T)和双氢睾酮(dihydrotestosterone， DHT)血清浓度，评价度他雄胺对雄鼠雄激素水平的影响；采用精密电子天平对各组睾丸、附睾、前列腺和精囊进行称重，评价度他雄胺对大鼠生殖器官重量的影响；采用HE染色法对各组睾丸和附睾进行组织学分析，同时采用透射电镜技术对附睾上皮细胞超微结构进行分析，评价度他雄胺对大鼠主要生殖器官组织学的影响。

And these estrogens,depending on the level of wastewater treatment,may not be completely broken down during sewage treatment,so they get discharged into rivers and streams.male fish exposed to the hormone become feminized,they produce the same proteins that female fish do to develop eggs,some males even develop eggs in their testes.
