Bats with weirdly giant penis have sex for up to 12 hours in a way never seen

Serotine bats that have penises seven times longer and wider than their
female counterparts' vaginas are the first known mammals to engage in
non-penetrative sex.

Serotine蝙蝠的阴茎比雌性蝙蝠的阴道长和宽七倍，是已知的第一个进行非插入式性行为
的哺乳动物。

交配）的哺乳动物。（图片来源：Alona Shulenko）
科学家发现，蝙蝠的阴茎“大得不成比例”，无法放入雌性阴道内，是已知的唯一一种无
需插入就能发生性行为的哺乳动物。
Bats with "disproportionately large" penises that don't fit inside the
females' vaginas are the only mammals known to have sex without penetration,
scientists have discovered.
Mammals usually mate via penetrative sex, but serotine bats (Eptesicus
serotinus) have evolved a different strategy. Instead of inserting their
penis into the female's vagina, males use their oversized genitalia to push
aside their partner's tail sheath, before pressing up against her vulva for
up to 12 hours, according to a study published Monday (Nov. 20) in the
journal Current Biology.
"We had observed that these bats have disproportionately long penises, and we
were always wondering 'how does that work?'," lead author Nicolas Fasel, a
postdoctoral researcher and evolutionary biologist at the University of
Lausanne in Switzerland, said in a statement shared with Live Science.
哺乳动物通常透过插入性交配，但塞洛汀蝙蝠（Eptesicus serotinus）进化出了不同的
策略。根据周一（11 月 20 日）发表在《当代》杂志上的一项研究，雄性不会将阴茎插
入雌性的阴道，而是用其超大的生殖器将伴侣的尾鞘推开，然后压在雌性的外阴上长达
12 小时。生物学。
“我们观察到这些蝙蝠的阴茎过长，我们总是想知道‘这是如何运作的？’”该研究的主
要作者、瑞士洛桑大学的博士后研究员兼进化生物学家尼古拉斯·法塞尔（Nicolas
Fasel ）在一份声明中说。与生活科学。
It turns out, it doesn't work — at least not like in other mammals. Their
penises are seven times longer and wider than the females' vaginal openings
when erect, making post-erection penetrative sex impossible.
"We thought maybe it's like in the dog where the penis engorges after
penetration so that they are locked together," Fasel said. "Or alternatively
maybe they just couldn't put it inside, but that type of copulation hasn't
been reported in mammals until now."

事实证明，它不起作用—至少不像其他哺乳动物那样。它们的阴茎在勃起时比雌性阴道
口长和宽七倍，这使得勃起后的插入式性行为变得不可能。
“我们认为这可能就像狗的阴茎在插入后肿胀，从而将它们锁在一起，”法塞尔说。“或
者也许他们只是无法将其放入体内，但到目前为止，哺乳动物中还没有报导过这种类型的
交配。”

Fasel and his colleagues analyzed footage from cameras they had placed on a
grid that the bats could climb, and where the animals' genitalia were visible
during copulation. They recorded a total of 97 mating events in the attic of
a Dutch church and in a bat rehabilitation center in Ukraine. None of the sex
sessions appeared to involve penetration.

法塞尔和他的同事分析了他们放置在蝙蝠可以攀爬的网格上的摄影机的镜头，以及在交配
过程中可以看到动物生殖器的位置。他们在荷兰教会的阁楼和乌克兰的蝙蝠复健中心总共
记录了 97 起交配事件。所有的性行为似乎都没有涉及插入。

Instead, the footage showed males grasping females by the nape and moving
their pelvis until their erect penis was pushed firmly against their
partner's vulva. The males then remained completely still in this embrace for
an average of 53 minutes, with the longest interaction lasting almost 13
hours.
The researchers noted the penises were enlarged before coming into contact
with the vulva, excluding the possibility of even pre-erection penetration,
which is known to occur in dogs.
The team also measured and described the erect penises of live serotine bats.
These animals develop erections under anesthesia, according to the statement,
enabling researchers to document a "heart-shaped" swelling at the tip of the
penis.
相反，影片显示雄性抓住雌性的颈背并移动其骨盆，直到其勃起的阴茎牢牢地推向伴侣的
外阴。然后，雄性在这种拥抱中保持完全静止的时间平均为 53 分钟，最长的互动持续了
近 13 个小时。
研究人员指出，阴茎在接触外阴部之前就已经增大，排除了勃起前插入的可能性，而这种
情况已知发生在狗身上。
研究团队也测量并描述了活体血清蝙蝠的勃起阴茎。根据声明，这些动物在麻醉下勃起，
使研究人员能够记录阴茎尖端的“心形”肿胀。
"The terminal swelling was adorned with a few short hairs and composed of two
large erectile tissues," the researchers wrote in the study. "We postulate
that the hair present on the terminal swelling serves as a sensor to assist
in finding the vulva."
Serotine bats may have evolved an oversized penis so they could push aside a
membrane that covers the females' genitals. "Bats use their tail membranes
for flying and to capture the insects [they eat], and female bats also use
them to cover their lower parts and protect themselves from males," Fasel
said. "But the males can use these big penises to overcome the tail membrane
and reach the vulva."
研究人员在研究中写道：“末端肿胀饰有几根短毛，由两个大的勃起组织组成。” “我
们假设末端肿胀处的毛发可以作为传感器来帮助寻找外阴。”
塞洛汀蝙蝠可能进化出了超大的阴茎，这样它们就可以推开覆蓋雌性生殖器的膜。法塞尔
说：“蝙蝠利用尾膜来飞行并捕捉[它们吃的]昆虫，雌性蝙蝠也用尾膜覆蓋下半身并保护
自己免受雄性蝙蝠的侵害。” “但雄性可以使用这些大阴茎来克服尾膜并到达外阴部。
”
The fur on female bats' abdomens appeared wet after mating, indicating the
presence of semen, but samples are needed to confirm that males ejaculate
during the long embrace, according to the study.
This is the first documented evidence of non-penetrative sex, also known as
"contact mating," in mammals. This behavior has been described in birds,
however, and involves males and females pressing together openings called
cloacae to perform "cloacal kisses," resulting in a transfer of sperm.
To better describe the mating behavior of serotine bats, Fasel and his
colleagues "are trying to develop a bat porn box, which will be like an
aquarium with cameras everywhere," he said.
研究称，雌性蝙蝠腹部的毛皮在交配后显得潮湿，显示存在精液，但需要样本来确认雄性
蝙蝠在长时间的拥抱过程中射精。
这是哺乳动物非插入性交（也称为“接触交配”）的第一个有记录的证据。然而，这种行
为在鸟类中已有描述，涉及雄性和雌性将称为泄殖腔的开口压在一起，进行“泄殖腔亲吻
”，从而导致精子的转移。
为了更好地描述血清蝙蝠的交配行为，法塞尔和他的同事“正在尝试开发一个蝙蝠色情
包厢，它就像一个到处都有摄影机的水族馆”他说。
