The search was conducted in six bibliographic databases: Cochrane, PubMed, Science Direct, Springer, Scopus, and Cinahl. The health sciences descriptors ¹⁹ used were: "Natural Childbirth", "Humanizing Delivery", "Humanization of Assistance", "Obstetric Violence", "Qualitative Research" and the Boolean operators AND and OR; the search equation was adjusted in each database.

Data evaluation complied with the following criteria: Qualitative full-text articles on women's experiences with vaginal childbirth in Spanish, English, and Portuguese, limited to the period 20102023 with a score of 8 or higher according to the Spanish Critical Appraisal Skills Programme (CASPe) ²⁰.

The included articles were analyzed, the extracted data were compared, and similar data were classified and grouped; themes were organized to facilitate the process of analysis and synthesis. The analysis was conducted using the proposal of Miles and Huberman ^18,21: data reduction, data visualization, data comparison, conclusion drawing, and verification.

The integrative review found 797 articles, which were reviewed by title and abstract; 522 were excluded because they did not meet the inclusion criteria, and 56 were excluded due to duplication. A total of 219 articles were submitted for quality assessment using the CASPe and 85 articles were included for analysis if they scored 8 or higher, of which 53 articles that did not focus on women's experiences were excluded, leaving only 32 documents that did meet the inclusion criteria for analysis.

The thematic analysis was performed with 32 selected articles; 603 units of meanings were obtained, which were consolidated and grouped into six thematic units, allowing the deepening of the meaning of the childbirth experience.

Forms of aggression manifest themselves in all areas and govern the daily behavior of human beings; aggressive behavior often becomes socially acceptable in forms such as microaggressions or subtle, routine expressions that may not overtly suggest violence but that nonetheless convey offensive messages, evoke feelings of inferiority, and assign culturally devaluing roles to individuals ⁵⁴; findings in the literature reveal that women in labor experience microaggressions, primarily due to the treatment they receive from healthcare personnel since they depersonalize the woman, isolate her in the process because they shift their focus solely to the medical problem or procedure, they do not talk to her, do not let her be autonomous and let her endure a significant amount of pain ^22,23,25.

Socioeconomic, ethnic, and cultural differences influence the care provided by health institutions; healthcare personnel fail to understand the unique challenges and barriers of women from lower socioeconomic backgrounds, resulting in them providing differentiated and disrespectful treatment, acting with disrespect towards this socially vulnerable population, making derogatory comments, particularly towards those who are single mothers, adolescent mothers, poor or uneducated ^22,25,31,50.

On the other hand, negative experiences of childbirth are socially shared, in terms of pain, and associated with fear and suffering since women expect mistreatment before entering the delivery room because they are unprepared or have insufficient knowledge, fear hospitals and distrust the staff ^22,43,52. The experiences that produce discomfort, insecurity and psychological damage generate macro-impacts that lead to the perception that health institutions are hostile and unsuitable environments for a natural and humanized childbirth ^23,24,26.

Childbirth is a natural process, and healthcare personnel and the community need to embrace their responsibility toward women, fostering empathetic communication, and support for those who have chosen to continue with their pregnancy and plan their childbirth, according to their unique characteristics, expectations and desires, ensuring they feel safe, comfortable and respected ^27-29, Women should have the freedom to navigate between different models of care, that is, the traditional model, rooted in cultural experience; and the biomedical or welfarist model, guided by the delivery care protocols managed by health institutions ^27,29,30.

Healthcare personnel are important in this experience, as they need to ensure that women feel safe within the facilities and trust them during the childbirth process; for this, they must be up to the task, without dehumanizing the procedure and cultivating empathy. To achieve this, appropriate facilities should be created for natural childbirth that provide a secure environment ⁵², in which knowledge, skills, values, moral and ethical principles for the care of women during pregnancy, childbirth the postpartum period are integrated, in addition to attending to their needs, respecting their body and their process, for an excellent experience during childbirth ^27,37.

Healthcare personnel have a crucial role in adhering to practices such as informed consent, reinforcing women's autonomy, and respecting their ability to freely choose interventions, whether from the biomedical or traditional model ^27,29,30. They should also offer women the option to select their birth companion and ensure they feel comfortable, preserving their autonomy throughout the vaginal birth process ^28,30.

Childbirth holds significant symbolic and cultural meaning, reflecting diverse social, cultural, and ethnic values ³³. Recognizing the profound value women attribute to childbirth, it is imperative to take proactive measures to prevent violence and ensure their respectful treatment, particularly during this pivotal process.

Globally, there is a widespread lack of awareness regarding human rights; women during pregnancy and childbirth are no exception. Lack of knowledge often results in a loss of control over their bodies, leaving them vulnerable to professionals who perpetrate violence against them, while they assume a passive role ^32,49, and the mechanisms for such mistreatments are unknown, leading women to prefer to remain silent ³¹.

Women who rely on the health system assume that the actions taken during their care are correct, preferring to remain silent rather than challenge those who violated their rights, they renounce their bodies so that healthcare professionals take care of everything for the sake of their baby, and once they hold their baby in their arms, they justify the practices they endured ^31,33,34 which, on occasions, can be so shameful that they prefer to keep quiet about them, which is why they hide them deep within themselves ^25,33.

Women in vulnerable conditions who are admitted to a health institution are repressed and must endure and remain silent during childbirth ⁴⁶; As a consequence of this, given their past experiences and what they have heard from others, they hide their plans and expectations for childbirth from society, because they believe the family may influence their decisions and that the hospital environment will not be friendly, nor will it share their decisions, so they believe that by remaining silent the delivery will be easier and faster, creating a favorable environment for obstetric violence and a bad experience ^31-34.

The sociocultural context often frames childbirth as a painful ordeal, dominated by norms dictated by healthcare personnel who know everything and decide everything, thereby limiting women's autonomy over their bodies. Painful childbirth is linked with previous negative experiences, which foster biases about vaginal childbirth in medical institutions ²⁶. Consequently, vaginal childbirth becomes a process where orders must be followed to facilitate the healthcare team's work ³².

Childbirth is a unique, special and unforgettable moment, that requires a profound physical and mental connection between the mother and her surroundings, but it does not necessarily need to occur in a hospital setting ³⁵; for some women, childbirth is a process influenced by their ancestors and origins, grandmothers and mothers; for this reason, they decide not to go to medical institutions ³⁵. Humanizing childbirth involves recognizing the woman as the central figure and interacting with her during the decision-making process regarding her care ^36,37,39.

Ideally, women should listen to their bodies and be able to make decisions based on the education they receive from the professional who helps them to clear up doubts and clarify concepts about childbirth ³⁵. Fostering empowerment and promoting self-education is essential for decision-making and management of childbirth from planning to completion. Providing complete information and adequate medical support to all women facilitates women's control of their childbirth ^35,40.

The education provided by health professionals should make women aware of their sexual and reproductive rights and include information so that they understand the meaning of obstetric violence, which will allow them to detect, stop and report it in time, to guarantee their integrity and dignity during labor. In addition, women should be able to choose the birth plan they want to have: traditional, home or water birth, which will strengthen their autonomy when making decisions ³⁸.

Some procedures are performed out of necessity to maintain or restore the patient's health; however, women should know which interventions are going to be performed ⁴¹; for this reason, respectful communication is fundamental, signing the consent form in which the professional informs when, why and how the delivery will be performed so that women know their state of health and share it with their companion; they should know the woman's evolution to provide support according to the particularity of the situation ³⁶.

Little is said about women's experiences during childbirth in health centers because the care is generally unsatisfactory; only when the mothers and their babies are at home do they share their negative experiences with family members ^31,48. In hospitals, medical interventions are frequently performed to expedite the delivery process, often without respecting the patients' wishes or considering cultural factors ^41,46; the staff acts in an insensitive manner, prioritizing interventions such as the Kristeller maneuver, routine episiotomies or forceps, most of which are unknown to them ^42,43,49.

Women tend to normalize these situations, adopting the role of the compliant patient, they do not bother and refrain from asking questions, fearing that opposing the decisions of healthcare personnel could lead to negative repercussions ^43,44; the healthcare personnel work without saying anything, through scolding or even physical force, they coerce women into adopting the correct position for delivery ^{41,44,45,47,48}, they speak without giving importance to the mother's process, their interest is solely focused on ensuring the fetus is born alive ^41,42,44.

Healthcare institutions and personnel often act disrespectfully, undermining women's empowerment ⁴⁸, they are insulted and ignored ^41,43,44; they use fear to coerce them into consenting to medical interventions under pressure; most of them sign consent forms for them to perform the procedure and expedite the delivery ^41,43. While some are grateful that they did not suffer more ⁴¹, this has repercussions and emotional imbalances that prevent them from developing a normal life after childbirth or alter their sexual and reproductive plans ^48,49. Professionals have normalized violence; this situation continues, and the subject is not discussed because very few women dare to report it since they have normalized this type of treatment ^32,42.

Childbirth is a rite of life in which assistance is provided without interventions or procedures and for which the Healthcare personnel become emotional and scientific support ⁵¹, since they provide privacy and good treatment during care ^52,53. Some women make a birth plan ^35,50 with which they take control and request privacy, limit the number of professionals present ⁵⁰ and obtain silence, make decisions and express themselves freely ^50,52.

Satisfying the woman's desires during labor makes this experience an enriching moment; water birth is a stabilizing, temporary and protective space that facilitates the transition of the baby from the uterus to the water ⁵¹, it can be performed in health institutions or with trained personnel who at the same time become educators and support for the women ^50,53. The best place for delivery is where the mother feels safe, as long as the home, the water or the health institution favors the mother-child bond ^51,52.

An essential factor in ensuring the satisfaction and dignity of women during childbirth is their companion, a guardian or protector who can prevent obstetric violence ^50,52,53. A partner who is involved throughout the gestation process and prepares alongside the mother for childbirth expresses the fulfillment of sharing and participating in this meaningful experience ^50,53.

The analyzed articles highlight positive childbirth processes. They show the patience, privacy and respect that the healthcare professional ^50,52,53 exhibits with the patient, going from being mere assistants to an accomplice and co-authors of the event, as long as there is a relationship based on communication ^41,53, with extensive discussions before starting the delivery, clarify doubts and provide a safe, healthy and satisfactory delivery for the couple ^41,52; This produces a positive impact at the individual and social levels, a positive experience that encourages them come again to give birth ⁴⁷ in those spaces where they feel safe and protected.
