Overview

What Is Gamete Intrafallopian Transfer?

Gamete intrafallopian transfer (GIFT) is a fertility treatment in which eggs and sperm are placed directly into a fallopian tube instead of being fertilized in a laboratory. The goal of this gamete intrafallopian transfer procedure is to allow fertilization to occur inside the body and support conception.

Unlike GIFT, in vitro fertilization (IVF) involves fertilization in a laboratory before an embryo is transferred to the uterus. In zygote intrafallopian transfer (ZIFT), the egg is fertilized in the laboratory first, and the resulting zygote is then placed in a fallopian tube.

Which Conditions It Treats

Which Fertility Problems Can GIFT Treat?

GIFT may be considered for infertility related to ovulation problems, unexplained infertility, cervical or intercourse-related factors, or selected male-factor infertility when sperm quality and quantity are adequate. A fertility specialist reviews both partners’ health and fertility findings before recommending this type of gamete transfer.

  • At least one fallopian tube must be open and functional so the eggs and sperm can be placed where fertilization may occur.
  • The ovaries must be able to respond adequately to medicines used to stimulate egg development.
  • Usable sperm must be available for collection and preparation.
  • The patient must be medically suitable for laparoscopy and anesthesia.

Eligibility

Candidacy has limits

Blocked fallopian tubes, severe sperm-factor infertility, significant endometriosis, or conditions that make laparoscopy unsafe may make GIFT unsuitable. Your fertility specialist can explain whether IVF or another approach is more appropriate.

During the Procedure / What to Expect

What to Expect During GIFT

Preparing for treatment

  • Ovarian stimulation medicines are used to encourage the development of several eggs.
  • Ultrasounds and blood tests monitor follicle growth and hormone levels during stimulation.
  • A trigger medicine is timed to help mature the eggs before retrieval.
  • Egg retrieval is performed using a procedure planned by the fertility team.
  • Sperm is collected and prepared so the most suitable sperm can be used.
  • Anesthesia is given for the laparoscopic placement procedure.
  • Using laparoscopy, the doctor places the eggs and prepared sperm into a fallopian tube.
  • Afterward, the care team monitors recovery before discharge and provides follow-up instructions.

The gamete intrafallopian transfer process usually takes place as a same-day laparoscopic procedure. Fertilization is expected to occur inside the fallopian tube rather than in a laboratory, and a pregnancy test is scheduled after the transfer according to your clinic’s instructions.

Risks & Benefits

Benefits and Risks of GIFT

Potential benefitsLimitations and risks
Fertilization occurs inside the bodyFertilization cannot be directly confirmed before transfer
May be considered when a couple prefers an intrafallopian approach and candidacy requirements are metRequires at least one open fallopian tube and laparoscopic surgery
May avoid laboratory embryo cultureSuccess depends on age, egg and sperm factors, tubal function, and other fertility factors
  • Ovarian hyperstimulation syndrome can occur when the ovaries respond too strongly to stimulation medicines.
  • Multiple pregnancy is possible if more than one egg is fertilized.
  • Ectopic pregnancy can occur if a pregnancy develops outside the uterus.
  • Infection is a possible complication of egg retrieval or laparoscopy.
  • Bleeding can occur after the procedure.
  • Laparoscopy can rarely injure nearby organs.
  • Anesthesia can cause complications or side effects.
  • GIFT may not result in pregnancy.

Recovery

Recovery After GIFT

Short-term effects may include pelvic cramping, bloating, fatigue, light vaginal bleeding, and shoulder discomfort caused by the gas used during laparoscopy. Recovery time varies, so follow the instructions from your fertility team and contact them if symptoms are concerning or do not improve.

  • Arrange for someone to drive you home and stay with you as recommended after anesthesia.
  • Follow all medication, wound-care, and activity instructions from your care team.
  • Avoid strenuous activity until your fertility team says it is safe to resume.
  • Attend scheduled monitoring visits so recovery and early pregnancy progress can be assessed.
  • Take the scheduled pregnancy test even if you have bleeding or symptoms that resemble a period.

Get medical help

Know the warning signs

Seek urgent assessment for severe or worsening pain, heavy bleeding, fainting, fever, breathing difficulty, marked abdominal swelling, or other symptoms specified by your fertility team.

When to Call a Doctor

When to Call a Doctor After GIFT

  • Contact your fertility clinic urgently for heavy vaginal bleeding.
  • Severe or one-sided pelvic pain requires prompt medical assessment.
  • Fever or chills may indicate an infection and should be reported.
  • Persistent vomiting can cause dehydration and needs medical advice.
  • Shortness of breath requires urgent evaluation.
  • Fainting or severe weakness should be treated as an emergency.
  • Rapidly increasing abdominal swelling may signal a complication.
  • Reduced urination should be reported promptly, especially after ovarian stimulation.

After a positive pregnancy test, one-sided pain, shoulder pain, dizziness, or fainting can signal an ectopic pregnancy. Seek emergency evaluation rather than waiting for a routine appointment if these symptoms occur.
