Aromatherapy for Mental Health Promotion in IVF Patients

April 24, 2026 updated by: Rubens Lene Carvalho Tavares, Federal University of Minas Gerais

Aromatherapy for Mental Health Promotion in In Vitro Fertilization Patients: a Randomized Clinical Trial

The experience of infertility can cause significant emotional instability, especially for patients awaiting In Vitro Fertilization (IVF) treatment, generating anxiety, stress, and depressive symptoms. This study is a randomized clinical trial assessing the effectiveness of aromatherapy in improving mental health and quality of life in women undergoing infertility treatment. 120 participants will be randomized into three groups (Intervention, Placebo, and Control). The intervention involves the inhalation of true lavender essential oil (Lavandula angustifolia) for four weeks.

Study Overview

Detailed Description

Infertility is a condition that affects approximately one in six people globally and is associated with high levels of psychological distress. Complementary therapies, such as aromatherapy, emerge as potential strategies to promote emotional well-being. This prospective, randomized, controlled clinical trial will be conducted at the Hospital das Clínicas da UFMG. Participants will be women on the waiting list for IVF. They will be randomized into three groups:

  1. Intervention Group: Inhalation of Lavandula angustifolia essential oil.
  2. Placebo Group: Inhalation of synthetic lavender essence.
  3. Control Group: Routine care only. The intervention consists of inhaling 5 drops of the substance using a personal nasal inhaler stick, twice daily (morning and night) for 15 minutes, over a period of 4 weeks. Efficacy will be measured using validated scales for anxiety, depression, stress (DASS-21), quality of life (FertiQoL), insomnia (ISI), Human Flourishing Scale (HFS), Duke Religiosity Index (DUREL), Visual Analogue Scale (VAS) for pain, General Health Questionnaire (GHQ-12) and a Qualitative questionnaire at baseline, immediately post-intervention (Week 4), and at follow-up (Week 8).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Lavender essential oil group
This intervention group will inhale 5 drops of true lavender essential oil (Lavandula angustifolia), administered via personal inhalers (olfactory sticks). The use of personal inhalers is a safe and widely used low-cost intervention that can be applied practically and accessibly, ensuring greater adherence to the protocol by the participants. The inhalation will be performed daily, upon waking in the morning and at night before sleeping, for four weeks.
The inhalation of lavender essential oil will be performed twice a day, preferably upon waking and before nighttime sleep. Participants will be instructed to settle into a quiet environment, lying down or sitting, to consciously perform the inhalation. The procedure consists of opening the inhaler, positioning it approximately 1cm from the nostrils, and beginning the inhalation through habitual breaths.The protocol stipulates that each inhalation session lasts 15 minutes, which can be timed on the participant's own cell phone. After the inhalation is finished, the inhaler should be kept closed. To facilitate monitoring and ensure adherence to the protocol, participants will receive a weekly schedule to record completed sessions and will be encouraged to keep an aromatherapy diary to record their perceptions and feelings throughout the study, providing qualitative data that will contribute to analyzing the effect of the practice on the well-being of women undergoing fertility treatment.
Placebo Comparator: Synthetic lavender aroma group
The placebo group will inhale 5 drops of a synthetic lavender aroma, also administered via personal inhalers. Inhalation will be performed daily, upon waking in the morning and at night before sleeping, for four weeks.
The inhalation of synthetic lavender essence will be performed twice a day, preferably upon waking and before bedtime. Participants will be instructed to find a quiet environment, lying down or sitting, to consciously perform the inhalation. The procedure consists of opening the inhaler, positioning it approximately 1 cm from the nostrils, and beginning the inhalation through habitual breaths. The protocol stipulates that each inhalation session should last 15 minutes, and the time can be timed on the participant's cell phone. After the inhalation is finished, the inhaler should be kept closed. To facilitate monitoring and ensure adherence to the protocol, participants will receive a weekly schedule to mark completed sessions and will be encouraged to keep an aromatherapy diary to record their perceptions and feelings throughout the study, providing qualitative data that will contribute to the analysis of the practice's effect on the well-being of women undergoing fertility treatment.
No Intervention: Control Group
The control group will receive routine care throughout the 4 weeks.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change from Baseline in Depression, Anxiety, and Stress Scale (DASS-21) Scores
Time Frame: Baseline (Time 0), Week 4 (Time 1, end of Intervention) and Week 8 (Time 2, 4 weeks post-intervention)
he DASS-21 is a set of three self-report scales containing 21 questions to measure emotional states of depression, anxiety, and stress. Each of the three subscales contains 7 items. Scores for each subscale range from 0 to 42 (calculated by summing the scores for the relevant items, which are scored from 0 to 3, and multiplying by 2). Higher scores indicate more severe symptoms of distress.
Baseline (Time 0), Week 4 (Time 1, end of Intervention) and Week 8 (Time 2, 4 weeks post-intervention)
