This week the National Institutes of Health (NIH) announced the start of a
trial for a male contraceptive in gel form. It's a big step in the search
for a birth control men can use, and if it works, it would fill an important
public health need.
According to the NIH, the gel called NES/T, contains a form of progestin, a
hormone that can prevent ovulation during pregnancy. It blocks natural
testosterone, reducing sperm production. The gel also contains replacement
testosterone to maintain normal sex drive and other functions.
It's applied to the back and shoulders daily and is absorbed through the
skin. Researchers will study around 420 couples for about a year to see if
the gel is effective in preventing pregnancy. But CBS News medical
contributor Dr. Tara Narula said it won't be available for use right away.
Since it's a first trial, more research will be needed down the road.
"For any product like this to move forward, it's going to have to be safe,
effective and reversible," Narula said.
Right now, there's no male birth control pill available. Narula said one
reason is because a lot of the research has been left to non-profits and
governments. Another issue comes down to biology.
"It's much harder to repress the production of hundreds of millions of sperm
that are produced every day versus one to two eggs produced every month,"
Dr. Narula said. "But researchers are saying look, it's time for gender
equity right now. We need to have more shared responsibility in family
planning." | y****i

“你说养了六个孩儿，是真的?”
“真个的。”
“图乐子没个够，还得添嘴！”
“男人图哩……”
“你不图?”
“我……”
“用药十番，保你厌了！”
“我用。”
晚间，俩人凑在厢房的油灯底下仔细剖析检验那些药面儿，欲用不忍用，却又不能不用
。天青再次疼得大抖，叼住了女人的肩膀，女人也疼，咬牙忍住了。
愤怒的杨天青把药包扬到地上，恍惚嗅到了辣椒面子的呛味儿。狗尼姑想必是在香灰里
搀了那物件儿，他和菊豆让个老窟窿给作践了。两个人用清水泡了身子，彼此抚慰了痛
苦处，有冤难申，终夜无眠。
杨天青却再也摆不脱老尼姑给的生动启发。他想到了肥皂，想到了蒿子叶，最后他还想
到了司空见惯的物质：醋。
他犹豫不决地策划着全新的举动。
洪水峪仿照邻村的榜样，成立初级社了。动员的干部找到杨金山，老东西歪在炕上装聋
作哑，死也不肯交出那十亩地。干部们找到天青，让他拿主意。他只是笑，嘿嘿地摊着
两只大手，像是很呆钝的样子。
