INÎRODUCTION AND SCOPE OF PAPER

How mlght laborlng r¡onen be provfded effeccive analgesLa and rellef fro¡¡ thedlstress thât Ls normattvely seen in Lamaze and Dlck-Read approaches toParturltlon?

The recent reports by Whipple and Komisaruk (L985, L988); and Mertinez-conezet a1., (1.988) in the U.S. denonstrated a significanc analgesic effect eliciredby anterlor vaglnal wall or C.spoÈ stimulation, The elegant studles by Zavlaclc,et aI., (1988), in Bratislava, Czechoslovakia, described fe¡nale urethralexpulsions evoked by digltal stlnulation and the grouping of these ¡¡omen intoresPonse types. And lastly, ny interviews of women recorded remarkable tales inwhich parturlcion was experíenced by some as a peak sexuoerotic event thatincluded arousar, voluptuous sensâtion and orgasm. Atr this suggested to ne a

novel aPPlicatlon of sexuoelotic sti¡ruIâtlon during parturltlon to t¡anege thedistress and progress of labor and dellvery, This is the Lmmodest proposal.

Similarlty of female physlological response in arousal/orFasm and 1n parturltionA woman's sexuel response, ¡t¡enstruation, labor, and lactatlon are aII

interrelated conplex phenonena whlch share co¡r¡mon features of both a psycho-neuroendocrinological and a subJectively experlenÈial nature. Kltzinger (19s3),spoke of the "f.ntense sexuality of natural blrrhn (p, 210). Horchner (1984) satd"there is a sexual aspect to blrth even lf 1t Ls usually suppressed or fgnored,,(p. 1.95). But NewÈon (1973) flrsc sald thet lromen lrere "trebly sensuous,';speclflcally, 1) durlng sexuar arousal and orgasm, 2) during labor and delivery,and, 3) during lactatl.on and breast-feedlng. She presented a llst of nineobservable sl¡ollarlties betneen sexual arousal/orgasm and unnedlcatedparturitlon. Hotchner (L984), in her book pregnancy and Childbirth, addedsewer¿I more parallels.

T'he strlking parallels are these: 1) Breathlng deepens, accelerates, rnay beheld and combined with Valsal.r" r"n"urut";1 2) VocalizaÈioris oey includegrunts, sighs, gasps, ¡ooans and screaDs;2 3) The factal expresslon nay beglassy-eyed, strained, pained or ,,torÊured,,;3 4) In both there occurs myoÈoniaand rhyttrnlc abdo¡ninar contractLon;4 5¡ cli"otar and waglnal engorgenent andlubrication Ls sinllar;) 6) The mucus prug of the cervix is lost fn earryparcuritlon and ls Io'osened during coltus. 7) Rhychrnic, nuscular patterns ofexpursf.ve-wave contraction of the fundus of the uterus have been observed insexual resPonse and orgasm that are idenÈical, except for strength, to those seenln labor (Masters & Johnson, 1966);6 8) The Ferguson'oxytocln,' reflex is

1 rn early sexual arousar and ln labor breathing deepens; rn later stages ofarousal and labor, breathtng rnay accelerate end Valsalva meneuvers nay béco¡nbLned with breath-hoÌdlng as olgesn approaches, or as "pushlngr ocàurs.2 the pattern of vocaLizatlon is sinilar, in chac a noman may grunt, gasp,qulckly draw in the breath, rnoan, and cry ouc in late flrst stag¿ labor, oi asorgasm approaches.3 As blrth or orgasn approaches, the facial expresslon becomes stralned,Lntense, or glassy-eyed. thÍs ts frequently inËerpreted as ',pained", or KLnsey,s"Èortured expresslon,' of orgasn.4 In both labor and sexual arousal and orgasm, rnyotonla and perlodiccontractlon of the abdoninaL nuscles occuls.5 The cumescence or engorg,ement of the cLicoris/vu1va,/uterus; the lubrlcationand "openÍng" of the vaglna is slmllar during sexual arousal and parturition(Hotchner, 1984; Crooks & Baur, 1987). Obstetricians have reported cliroralengorgeu¡ent during parturition.6 Hochtner (L984), adds that ln orgasrn the genirals and "p.C." area spasmrhythmically wlth 8 to 12 "throbs", whereas in blrth there are hours of regularand progressively stronger contracÈions, Many women also have sirnilar uterinecontractions, experience sexual arousal and even orgas¡n during the breast-feedingof their infants.

l3l

ellcited ln each;' 9¡ In both there occurs a naturaL analgesla orinsensl.tivlly to nornalLy palnful stlnull;8 1-0) During both there may occuroblfvl.ousness to surroundlngs, arnnesÍas, changes in perceptlon and loss of

qconsciousnesq - 11) After delivery, as after orgas¡¡, nomen are often suddenlyful1y awake, aware, alert and energetlc. 12) The conmon emoEfonal responseimnediately post-partum and orgasm is njoyful ecstasy,', and usually strongfeellngs of well-belng.

RePorÈs from parturient wo¡oen who had experLences of pleasurable sensualltyand even orgasr¡ in chlldblrth support the parallels presented above. Sources ofthese reports fnclude Kltzinger (1983); Hite (1976); Lådas, IJhipple, and peny(L983); Hotchner (198a); and the ferv lnrerviews that I have done of uothers lnthe Roanoke, VirgLnla area. Notably, rrlth the exception of Perry, these cltatl-onauthors are elEost all wonen, speaklng of their own experLences.

Durlng sex play, female response and experl.ence to sexual or erotlc arousalranges from awersion, apathy, anesthesia, and anorgasula, on Èhe negative end ofthe conÈfu¡uum, to avi.d relish, delight, and "multiple orgasn" on the posttiveend. UÈerine conÈrâcÈions occurring in che context of sexual orgasru are usuallyexperienced as pleasurable by roost lrouen; whereas some fers experienceunexplalned, chronf.c pelvf.c pain nlthout pathology, wlth dyspareunia or palnfulcoltal or postcoLtal spasns and craroping of the uterr¡s (Black, 1986).

Dlfferences ln llbido durlng pregnancy also exist anong rromen, and probablyvaries ln any wo¡oan during her pregnancy. Ilhereas some wonen reporc Èhat sexualaccivfty Iate lnto thelr pregnancles is che lasÈ thing that they wouLd conslder,due to discomfort and appearance concerns, some faf.r nr¡mber of other wonên,

accordtng Èo Kitztnger (1983), report noderare ro greeÈly helghtened IIbIdo,sexual actlvity and response ln the second trLDester. Thls ls probably partiallydue to pressure ln and engorgenent of the genital organs. One ¡¡o¡nan reportêdÈhat late inÈo the third trlnester she entered e state of erotic arousal untilche moment of labor and kept that feeling rlght thlough chtldbirth (Kitzinger,

The body becomes lnsensitive to nornally painful stlurull.I.Iornen rnay report a naturally occur¡ing vulval anesthesia or cannot feel thebaby's head emerge or the episiotony lncision vrhen f-c is made.9 Durlng both parturltlon and sexual response $romen may beco¡ne oblivious totheir surroundlngs.

Let us no¡r consider specfflcally the uterlne contractl.ons of parturLÈIon.Flrst the mechanlsns which rnay lnltlate labor, and secondry how thesecontractlons are experienced or are at reast described by sorne wonen.

Natural onset of labor: netural mechanisms r¡hich mav lnicÍate or lnduce laborThree psychoneuroendocrlne nechanÍsns inpllcated fn Èhe onset and

¡nalntainence or labor are of Lnterest to us: 1) Endogenous oxytocin fron theDocÌ¡er's own hypothala¡us and pltultary nay in parc be responslble for laborrsonset. Yet' suPPortlve evldence for oxycocln betng the sole lnltlating factor lnIabor fs lirnlted (Olds, er a1., 1980, p.430), 2) Tt¡e Dost recenr endsubstantlated of the lnlÈietlon theorf.es holds that prosËaglandtn Ls responsLblefor the lnitlatlon of labor. rndeed, exogenous prostaglandtn pGE2 vaglnalsupposltorLes have been used obstetrlcally for the fnductlon of labor, and we may

notê here for l¿ter ¡eference chat the most concer:rtrâted soufce of naturellyoccurrfng prosreglandln is found f.n semen (Klrzinger, 1gg3). 3) Lfgglns (1973)de¡¡onstråtêd thet fêtâl cortfsol nay play an f.mportant role ln the lnltl.atlon of

Thls phenoroenon has not been conflrned Ln hgmans, but ltls bqlleved that a stress responsê, wlth che attendant rise Ln Ac11¡ tLters viathe linbic-hypothalånfc-h)æoposeal axis, can lnduce hunan labor. However, onceinduced, labor nay subsequently be t¡ihlblted by further psychologlcal srressors.the cortisol theory clearly inplf.cates the role of psychological factors in laborlnitlation and inhfbftlon. rt seens qutte likely, however, theÈ nore chan oneneuroendocrine mechanisn 1s lnvolved ln the initfation and nalntenance of labor.

Ilith thls brief and superficlal revler¡ of the etlology of labor let us nor¡

conslder two possibfllÈLes, flrst, the proposed use of sexuoerotlc stimulation 1nthe induction of Iabor, and secondly, its use in the nanagenent of the progressand distresses of labor,Induction of labor through sexuoerotic stlnulatlon

There ls evf.dence that orgâsn rnay also serve es an ald to the lnductlon oflebor. Mesters and Johnson (1.966) tn thelr Hu¡nan Sexual Res after notingthet the expulsive contractlons of labor and orgasrn differed only in lntensity orstrength, actually specurated about the potential clinlcal slgnlficance oforgasnLc lnductlon of labor. One ¡¡onan I intervlewed (Colson, 1986) reportedlyinduced her or¡n Past-due labor through 'tlovemakingrr and orgasn. The contractlor¡sof labor began shortly after her orgasms ended. Tl¡is was a procedure she hadlearned frou her nidwlfe and Èhrough her prrepartun readlng. rnteresclnglyenough, i! fs reported by Kfrzlnger (1983), rhac Japanese obstetrlcar practlcesupposedly utilizès a cervical vibraÈor for the Lnducement of labor.

Labor has been fnduced through Èhe use of pGE2 suppositorfes. But the nostco¡rcentrated source of naturally occurring prostaglandin is semen. Kltztnger(1983) even describes a step-by-step procedure usl.ng lovenaklng and senen for theinductlon of labor. IJhether these sexuoerotic techniques nay safely, efflcientlyand rellably lnduce labor only re¡¡ains to be quanÈified. Let us now conslder thesecond proposal.

Management of progress or rate of labor through sexuoerotLc stinulationThrough breast and nipple stlmulation. Nipple sclnulatLon during sexuoerotic

play or breast feeding norrnally results ln a reflexlvè pituLtary gland release ofoxycocln (Ferguson 1941). Tactile rnanipulation of the nlppre seens to producethe same result during parturition. Thls neuroendocrine phenomenon has beenknor¡n for years, and ln folk ¡nedicine this technfque has been reported as betnguseful fn nldwifery. Ida May Gaskin, in her remarkable book Splritual Mfdwlfe¡y,

12 Appropriately, in october, L986, radl.o news described a curlosity about rheeârchquake Ln San Salvador. It seened thaÈ the Salvadorian hospltal rnedÍcalstaffs reported a rush on che lesouroes of their obstetrical r¿ards,Labors and deriveriês were occurring in record numbers with nany of them beingPrenacure.13 The nature of the contraccions elicited by Pitocln IV lnfusion (an exogenousoxytocin) are ofÈen nuch stronger and shorter in duration Ëhan ',natural"contractions.

(1978, p. 443) wrote that if lnhibltion had slowed the progress of labor, and ifthe husband rsas reluctant co sÈinulaÈe bis nife's breasts in the presence of the

nldwlfe, then cbe ¡nfdr¡ife would stlmulate them. That cornrDunfty of ¡nidwives had

knor,¡n for years that Èhfs nipple stinulation rsould lnduce stronger conErectf.ons

of the uterus. They were also rpelL artare thac reflexive oxytocln from the

pltulcary nas the causatLve mechanisro, yec they indlcated a preference for breast

stinulation over the nless pleasant IV drlp" (L978, p, 443) to Lnduce or speed-up

labor once begun. A very sf¡ollar, precisely tiried, step-by-step, nlpplestinuletlon technlque ls also descrl.bed by Kltzlnge¡, (1983, 9. 2O9).

Through vu1ual, clltoral, vaginal, and cervf.cal stinulatlon. But stlmuletlonof breast and nipple seens only one nodallcy of oxytocln release to augnent the

pace of labor. Newton, Foshee and Ner¡Èon (1966) mentLoned thet whereas laborcould be slowed by dlsturbance or change in the envtroriner¡t, lt could also be

augû¡enÈedby ngentle sclmulation of the lower genLtal trectn, (p. 375), but what

preclsely was Eeant by thls is not c1ear.

Physlologv and psychology of paln and "suffering" ln labor and dellwerythe experlence of pain as "suffering" is Èhe result of fnteractlon or sJmergy

beÈ¡reen neuro-physiological and psychologlcaL factors, Both atÈenÈion and

dLstractlori can fnpacc the experience of pain. AÈtendlng to sènsêÈions of painhelghtens the intenslly, whereas disÈraction froro the ser¡satlons can lncreasepain tolerance. Ar¡xlety greatly aopllfles the experience of pafn; and, of course

the experience of pain lncreases anxiety in a terrible negatLve spiraÌ.Sufferlng as the resul! of "paln", or sensations chat would ordinarily be

considered aversLve or noxious, is also related to the signlflcance or "meanint"of chese sensory events to the lndlvldual and his/her anxlety levels - and all ofthis is usually Èhe result of socialization. This is parclcularly trueconcerning the culÈure's imparted etticudes and bellefs toward labor and

chlldbirth. Ìfe are taught, and then have general expectatlons tshac the

experlence should be awful - with atcendant pain and sufferi.ng (Newton, 1970).

I really believe, nith Newton (1955), that the interpretaclon of the

experience of labor, and Èhe quality of the experience lcself, depends to sorne

extenc on the nind-seÈ and expectatlons of the womari in labor, BuÈ r'orfren have

experienced birth with paln, angulsh and terror, et one extreme, or wiÈh JoyfulantlcipeÈion end "blrÈh orgasns" at the other.

'trt absorutely dtd not hurtr', she told me al¡nost aporogeticalry, Herseven hours of labor were "1lke a roller-coaslern and she nsinply !ùent for therlde". A cor¡trecÈion of labor was descrlbed as, nthlnk of yoursel,f, or of yourbelly' as an orange, and a glant hand on you beglns to sgueeze you with greatpressure and then lecs up', (Colston, 1986).

the sensatlons of labor are not regarded as palnful by NavaJo nor¡e¡¡.Relatlves come and brlng food to eet and ceÌebrate the bf!Èhlng of the chlld(olds et a1., 1980). And, it is co¡omonly observed that nouen of nany othercultures can have a so¡oes¡hat dlfferent experLence wf.th labor, so¡ûe better, so¡enorss, because their expectations end aÈtltudes tonard childblrching, the resultof alternative socialÍzetion, are different Èhan those of Western or Anerlcan

15womèrì .

Today there exlst subcultures ln the U.S. whlch apparently utilfzealÈernatlve mlnd-sets, a rèstructurlng of eccitude and expecÈaÈlons, stronghuaanlstic, Lnterpersonal.-splrituar approaches, and subtle or ovêrcry explrcltsexuoerotic technlques, to provide freedon from anxiety, enoElonar support,rellef, dlstraccton, pleasure and relaxatlon; and consequencly, effectfveanalgesia for thefr laboring lroDen. One such alternate-culture roidrtfe, Ida t{ayGaskln itrote Èhat the concractlons of labor need not hurt. Thac chey are nenergy

evidence for a physiological u¡echanisn of sexuoerotlcally produced analgesLa thatmay be utll.ized in labor and delivery.

Analßesla frorn sexuoerotlc stl.mulatlon: Experf.mental evLdence and probablemechanlsm

Naturar somatic analgesics are åpperently rereased by the nervous systen Lnresponse to palnful. stl¡riuli (as ls conplexly described by Basbaum and Fields,1984), so lt see¡¡s logical that they ¡¿ould also be released during labor as welL,They are.

Verily, pregnancy may be called "expeccing" becâuse you getwhat you expect,

pregnant women shoned a substantlar l.ncrease during labor end dellvery, nith a

rapid decline after trvo days postpartum.16 TLr."" findlngs suggest thatendogenous opiaces present et this cime may lndeed provide analgesia durlng laborand dellvery. The exact ¡oechanlsn for this endorphin release is not known.

The lnvolve¡nent of endorphins ln the human sexual_ response cycle, andspecifically Lcs release during the orgasrnlc phase, has been lnvestigeted bySchreier (L983). She measured plasrna endorphin leve1s before and after orgasmand found a slgnlflcant Lncrease ln pLasna endorphln and prolactf.n.Unfortunately, chls study used only urale volunteers who masturbated to orgasn,but r belleve thar si¡rilar changes r¡ould also be found in sexuoeroticallystinulated or orgasnic fenales.

Research by Konlsaruk (tn 1974), and nore recently, by lfhlpple and Komlsaruk(1985, 1988) suggests strongly that anterior ¡vall vaglnal sti¡¡uletion, of a sortusually reported by wonen as feellng erocLc even to orgasm, nay be responsiblefor another mechanisn thet slgnificantly raLses paLn thresholds. Koroisaruk(L974), firsÈ denonstrated a nlce anargeslc effect frorn the gentle glass rodsÈrmuLatlon of the vagina and cervlx of fernale rats. Íhf.s procedureslgnificantly dioinlshed the animals' sensiÈivity to the pain of foot-pinch andincreased the acÈtvlty of neurons in the midbrain perlaqueductel grey natter, Itwas also speculated thet copulation and/or the blrth process would sinirarlystimulate the vagino-cervical region, and that this sensory-neural input wouldacÈl.vate the endorphln circuLcry of the nldbraln periaqueductel grey aree toproduee the analgesi.a.

Leter, l.IhtppLe and Ko¡¡isaruk (L985, 19BB), reported rhaÈ self-appliedstinulatioû of the anterl-or vaginal wall (,,c-area',), with fir¡¡ or deep pressurethet could evencuarly resurt Ln orgasn, produced an effect that slgnlflcentlyelevated the paln threshold. the shift was dramatLc: vaginal self-stl¡nulatl-onproduced slgniflcanc analgesla ln hurnans. rÈ decreased paln detectionsensLtivity 1.07 percenc; lncreased the paln tolerance threshold 75 percent, butdid not affect tactiLe or touch sensitivlty. Most recenÈly, thls powerfulanalgesic, but not enesthetic effect, in both raÈ and human fenales, producedthrough what Komisaruk et al. (1988) called "vaginal mechano-sÈirnulationn (VS),has been attrl-buced tc the release of the neuropeptide vasoactlve intestinelpeptide.

I believe these oÈher$tise natural sexuoerotl.c experlences of parturltion arèsuppressed or ignored out of erotophobla, an Lrratf.onal sensE of sho.e, anxfety,and gu11t. Kitzinger (1984), reports that this 'lntense sexual feellng, a

slgnlficant part of the experiences of ¡Darry \romen durlng chlldbirth, disturbsthem beceuse iÈ Ls sexuel and because they can do nothLng Èo prevent ltn(p.210). Slnllar dynamlcs of erotic feeling and guilt prevent soue wouen fronbreastfeedlng thelr Lnfants.

lntestinal pepttde nechanLsm for analgesla and pJ.easure durlng the process ofparturition, whlch leglcinately may non be considered an extenslon of fenalesexuallty. lllthln a permlsslve social, enotlonalIy and psychologically suitableenvironment, sexuoerotic sÈ1mulaÈf.on now seèms plauslble as a potent naturalrnethod of fntervention in the management of parcurltLon. Indeed, thesetechniques have apparencly already been successfully applied to provlde analgeslaand to manage the progress of parturltlon by thè nidwlves we no¡{ discuss below(see Gaskin, 1978).

Sexuoerotf.c stlmulation by spouse or lover. Sexuoerotlc stinulaclon can be

provlded by a husband, ¡nate, or partner. Midwlves in rural Floyd, Virginla, and

on a cornmune in SummerÈos¡n, Tennessee, nay lnstÍuct a laborlng couple on ho$r to

"get 1t on", meaning to relax and engage ln loving and effectfve sexuoeroticstsiurulatlon, because they have found thaC sexual sllnu1atlon provided by aspouse, in privacy, can promoËe relaxatlon, analgesia, and pleasure during laborand bi¡th (Colson, 1986; Gaskin, 'l-977, p. 352).

L7 The physiological arousal may occur, with analgesia, but the subjecclvesexuoerotic experience may sirnilary be suppressed, ignored or nisinterpreted.See Zaviacic et al., (L988), for "types" of responders.

somecines sinply lncorrect, lf not totelly the opposite of r¡hat ls rearlty (e.g.

Of course, any consfderation of the feasibility of sexuoerotl.c stinuletlonand response ln che Eanageuent of parturltion must recognize the lnpact of ouror¡n soclalfzation upon an ewaluation of the propriety of lntroducing such overtlyerotic techniques into ¡nedlcal practice.

Protocol for lnclusion of sexuoerotic stimulatlon Èechnlques as part ofchildbirth preparatlon

l{omen, and couples, nusc assume '¡ore accl.ve responslbllity for thelrchlldbearlng. They roust take charge and arrange for suitable prenatel nedlcalcare. They must learn as ¡¡uch as posslble about the reproductlve and gestatlonalprocess and abouc v¡hat to expect during the pregnancy. And they:¡ust learn,practice, and successfulry incorporate sexuoerotic stinulation end responsetechnlques, designed to manage their labor and delivery, into thel.r overallprepartum traÍnfng progren. The resulÈ mey then be less anxf.ety, lessdiscomfort, a greacer feellng of personal control over the blrthlng process, andconsequer¡tly, a more Positive, enJoydble, and emotÍonally rewardlng parturltlon.. The elernents of a cooprehensive prepartum educatl.onal and trainlng prograûwould include:1) General sexuality education, not merery reproductLve education: soneinstructors already accèpt thet thi.s should be part of childbirthl.ng classes.StudenÈs would be taught that labor and chlldblrch are qulte naturally regardedas dimensÍons of fenare sexuallty; thet the birth process can be regarded assexuoerotl.c and sensual, and is, at least by some wo¡netr, experienced aspleasurable and sexually satlsfying or even profoundly orgasmic. z) overarlcardiovascular and uruscoloskeletal condl-tionl-ng methods and exercLses: AnernphasLs should be placed on training of the Kegel or pelvic floor ¡ouscles forstrong posiÈive and voluntary contraction or relaxatlon. 3) Tralnlng andextensive practlce ln Ed¡nund Jacobsen's "progressive Relaxatf.on" technlgue orl'lolpe's "Syste¡natic Desensltization". this would aIlow voluntary and i¡¡¡nedlatedeep muscre relaxatlon durlng parturltf.on. 4) Trafning and practice inaPProPrfate anÈerior vaginal wall sti¡nulation to elicit the analgeslc effects:

ConcLudlng renarks and recommendations for furÈher researchI have been fascinated by the descrf-ptf.ons of these "spiritual" and very

lfould these techniques and these attltudes ettending chlldbirth now beingexplored by chese subculcures, be nore acceptable to the "mainstrean" if these
