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蝙蝠的陰莖比雌性蝙蝠的陰道長和寬七倍，是已知的第一個進行非插入式性行為
的哺乳動物。

交配）的哺乳動物。（圖片來源：Alona Shulenko）
科學家發現，蝙蝠的陰莖“大得不成比例”，無法放入雌性陰道內，是已知的唯一一種無
需插入就能發生性行為的哺乳動物。
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.
哺乳動物通常透過插入性交配，但塞洛汀蝙蝠（Eptesicus serotinus）進化出了不同的
策略。根據週一（11 月 20 日）發表在《當代》雜誌上的一項研究，雄性不會將陰莖插
入雌性的陰道，而是用其超大的生殖器將伴侶的尾鞘推開，然後壓在雌性的外陰上長達
12 小時。生物學。
「我們觀察到這些蝙蝠的陰莖過長，我們總是想知道『這是如何運作的？』」該研究的主
要作者、瑞士洛桑大學的博士後研究員兼進化生物學家尼古拉斯·法塞爾（Nicolas
Fasel ）在一份聲明中說。與生活科學。
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."

事實證明，它不起作用—至少不像其他哺乳動物那樣。它們的陰莖在勃起時比雌性陰道
口長和寬七倍，這使得勃起後的插入式性行為變得不可能。
「我們認為這可能就像狗的陰莖在插入後腫脹，從而將它們鎖在一起，」法塞爾說。“或
者也許他們只是無法將其放入體內，但到目前為止，哺乳動物中還沒有報導過這種類型的
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.

法塞爾和他的同事分析了他們放置在蝙蝠可以攀爬的網格上的攝影機的鏡頭，以及在交配
過程中可以看到動物生殖器的位置。他們在荷蘭教會的閣樓和烏克蘭的蝙蝠復健中心總共
記錄了 97 起交配事件。所有的性行為似乎都沒有涉及插入。

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，影片顯示雄性抓住雌性的頸背並移動其骨盆，直到其勃起的陰莖牢牢地推向伴侶的
外陰。然後，雄性在這種擁抱中保持完全靜止的時間平均為 53 分鐘，最長的互動持續了
近 13 個小時。
研究人員指出，陰莖在接觸外陰部之前就已經增大，排除了勃起前插入的可能性，而這種
情況已知發生在狗身上。
研究團隊也測量並描述了活體血清蝙蝠的勃起陰莖。根據聲明，這些動物在麻醉下勃起，
使研究人員能夠記錄陰莖尖端的「心形」腫脹。
"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."
研究人員在研究中寫道：“末端腫脹飾有幾根短毛，由兩個大的勃起組織組成。” “我
們假設末端腫脹處的毛髮可以作為感測器來幫助尋找外陰。”
塞洛汀蝙蝠可能進化出了超大的陰莖，這樣它們就可以推開覆蓋雌性生殖器的膜。法塞爾
說：“蝙蝠利用尾膜來飛行並捕捉[它們吃的]昆蟲，雌性蝙蝠也用尾膜覆蓋下半身並保護
自己免受雄性蝙蝠的侵害。” “但雄性可以使用這些大陰莖來克服尾膜並到達外陰部。
”
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.
研究稱，雌性蝙蝠腹部的毛皮在交配後顯得潮濕，顯示存在精液，但需要樣本來確認雄性
蝙蝠在長時間的擁抱過程中射精。
這是哺乳動物非插入性交（也稱為“接觸交配”）的第一個有記錄的證據。然而，這種行
為在鳥類中已有描述，涉及雄性和雌性將稱為泄殖腔的開口壓在一起，進行“泄殖腔親吻
”，從而導致精子的轉移。
為了更好地描述血清蝙蝠的交配行為，法塞爾和他的同事「正在嘗試開發一個蝙蝠色情
包廂，它就像一個到處都有攝影機的水族館」他說。
