Background

The role of prostaglandins for cervical ripening and induction of labour has been examined extensively. Human semen is the biological source that is presumed to contain the highest prostaglandin concentration. The role of sexual intercourse in the initiation of labour is uncertain. The action of sexual intercourse in stimulating labour is unclear, it may in part be due to the physical stimulation of the lower uterine segment, or endogenous release of oxytocin as a result of orgasm or from the direct action of prostaglandins in semen. Furthermore nipple stimulation may be part of the process of initiation.

This is one of a series of reviews of methods of cervical ripening and labour induction using standardised methodology.

Objectives

To determine the effects of sexual intercourse for third trimester cervical ripening or induction of labour in comparison with other methods of induction.

Search methods

The Cochrane Pregnancy and Childbirth Group's Trials Register (June 2007) and bibliographies of relevant papers.

Selection criteria

Clinical trials comparing sexual intercourse for third trimester cervical ripening or labour induction with placebo/no treatment or other methods listed above it on a predefined list of labour induction methods.

Data collection and analysis

A strategy was developed to deal with the large volume and complexity of trial data relating to labour induction. This involved a two-stage method of data extraction.

Main results

There was one included study of 28 women which reported very limited data, from which no meaningful conclusions can be drawn.

Authors' conclusions

The role of sexual intercourse as a method of induction of labour is uncertain. This is an important issue to pregnant women and their partners. There is a need for well-designed randomised controlled trials to assess the impact of sexual intercourse on the onset of labour. Any future trials investigating sexual intercourse as a method of induction need to be of sufficient power to detect clinically relevant differences in standard outcomes.

Sexual intercourse for cervical ripening and induction of labour

The role of sexual intercourse as a method for induction of labour is uncertain.

Human sperm contains a high amount of prostaglandin, a hormone-like substance which ripens the cervix and helps labour to start. Sometimes it is necessary to help start labour and it has been suggested that sexual intercourse may be an effective means. However, there is not enough evidence to show whether sexual intercourse is effective or to show how it compares with other methods. More research is needed.

背景

以進行性行為的方式來促進子宮頸軟化及引產

前列腺素(prostaglandin)用在促進子宮頸軟化與引產方面的角色,已經有了廣泛的調查。人類的精液被認定為含有最高濃度的前列腺素之生物性來源。在進行分娩的起始點上,性行為的角色並不清楚。在刺激分娩的時候,性行為的作用並不明確,有一部份的原因可能是性行為會在子宮較低的部位帶來生理刺激,或是因為性高潮或精液的前列腺素直接產生作用因而促進分泌催產素(oxytocin)。除此之外,刺激乳頭也可能是啟動過程的一部分。這是使用標準方法來回顧子宮頸軟化和引產的系列之一。

目標

跟其他的引產方法比較起來,對第3孕期促進子宮頸軟化或是引產,要決定性行為在其中的功效。

搜尋策略

The Cochrane Pregnancy and Childbirth Group's Trials Register(2007年六月)以及相關期刊的參考書目。

選擇標準

針對第3期的促子宮頸軟化或是引產,臨床試驗將性行為與安慰劑/不採取任何治療或是其他列在它上面的方法進行了比較,而這些方法又是寫在引產方法的預先定義清單上面。

資料收集與分析

發展出一套策略,用來處理跟引產有關而且又大又複雜的試驗資料。這裡面包含了2階段的資料擷取方法。

主要結論

當中有1份共包含28名婦女在內的研究,曾經報告過非常有限的資料,並沒有辦法從裡面歸納出任何有意義的結論。

作者結論

將性行為當作是一種引產的方法時,它在當中扮演的角色還無法確定。對於懷孕婦女及她們的伴侶而言,這實在是一項重要的問題。我們需要有經過妥善設計的隨機對照試驗,來評估性行為在分娩開始時的影響。關於將性行為當作一種引產的方法時,將來任何在這方面的研究都必須具備充足的份量,以便在標準狀況中偵測臨床方面相關的差異。

總結

將性行為當作是一種引產的方法時,它的角色還無法確定。人類的精液中含有很大量的前列腺素,而前列腺素是一種類似荷爾蒙的物質,可以用來促進子宮頸成熟,並且幫助啟動分娩過程。有時候,幫助分娩過程啟動是有必要的,而且人們也認為性行為可能會是一種有效的方法。然而,關於性行為是否有效用,或是它跟其他種方法比較的結果,這些都沒有足夠的證據可以證實。還需要有更多的研究。
