Assisted reproductive technology (ART) encompasses a range of medical procedures used to address infertility and assist individuals and couples in achieving pregnancy. Since the first successful birth from in vitro fertilization (IVF) in 1978, ART has evolved into a highly specialized and rapidly advancing field that integrates reproductive endocrinology, embryology, genetics, and personalized patient care. At its core, ART involves the handling of both eggs and sperm outside the human body to facilitate fertilization. Common techniques include IVF, intracytoplasmic sperm injection (ICSI), and embryo cryopreservation, with newer advancements such as preimplantation genetic testing (PGT) and time-lapse embryo monitoring further refining outcomes. These technologies offer hope to patients facing a wide range of reproductive concerns, from age-related infertility and male factor issues to genetic disorders and same-sex family planning. Understanding the indications, protocols, and laboratory processes behind ART is essential for healthcare professionals involved in fertility care. This course offers a comprehensive overview of current and emerging techniques in ART, including indications for use, recommended techniques, and common complications.

Assisted reproductive technologies (ART), as defined by the Centers for Disease Control and Prevention (CDC), are fertility-related treatments in which eggs or embryos are manipulated. Procedures where only sperm are manipulated, such as intrauterine insemination, are not included under this definition. Additionally, procedures in which ovarian stimulation is performed without a plan for egg retrieval are also excluded by definition. The first successful human in vitro fertilization (IVF) was performed in England in 1978—a woman had an unstimulated menstrual cycle, and physicians performed a laparoscopic retrieval of a single oocyte from the ovary. The oocyte was then fertilized in vitro and subsequently transferred as an embryo into her uterus.[1] Since its inception, IVF has undergone significant technological advancements and has become widely accessible worldwide. IVF remains the most commonly utilized ART procedure. IVF remains the most commonly utilized ART procedure, and a clear understanding of IVF principles, related ART techniques, and their appropriate application is fundamental to clinicians’ practice.

While ART has significantly improved outcomes for individuals and couples facing infertility, the procedures are not without risks. Understanding the potential complications associated with ART is crucial for making informed clinical decisions and providing comprehensive patient counseling. Ovarian Hyperstimulation Syndrome OHSS is a potentially fatal complication of controlled ovarian stimulation. The reported incidence of OHSS, based on diagnostic criteria, is estimated to range from 1% to 5% for moderate-to-severe cases.[14] OHSS develops from the exogenous administration of gonadotropins followed by the administration of hCG. In this process, many follicles are recruited and develop within a single cycle, resulting in the excessive production of various growth factors, such as vascular endothelial growth factor (VEGF), and subsequent neovascularization. The combination of excessive follicular growth and fluid and vascular development leads to significant fluid shifts to the third compartment, resulting in ascites, edema, pleural effusion, renal injury, pericardial effusion, and thromboembolism. Patients at particular risk of OHSS include those with a diagnosis of PCOS, multi-follicular development, a large number of oocytes retrieved (>24), and elevated estradiol levels (>3500 pg/mL).[43][44] For patients diagnosed with moderate to severe OHSS, treatment involves supportive care with fluid resuscitation, therapeutic paracentesis, and prophylactic anticoagulation. Patients at risk for OHSS must not have a fresh transfer and must freeze all embryos until their ovarian stimulation has subsided. The final maturation trigger should be changed from hCG to a GnRH agonist if possible. In addition, cabergoline can be administered daily for 8 days after oocyte retrieval or after trigger administration to protect the patient from OHSS further. Then, 1 to 2 months later, when the ovarian stimulation has resolved, the patient can safely proceed with a frozen embryo transfer. Antenatal and Neonatal Complications

Antenatal and Neonatal Complications The most common complication of ART is the risk of multifetal gestation. In 2009, 41.1% of infants conceived via ART were of multifetal pregnancies (compared to 3.5% of infants in the general population).[45] The effort to reduce multifetal gestation via reducing the number of embryos transferred at once has resulted in a significant reduction—by 2017, 73.6% of ART-conceived infants were from singleton pregnancies.[37][46] Multifetal gestations have both maternal and fetal consequences. These pregnancies have a higher likelihood of various antenatal complications, including hyperemesis gravidarum, gestational diabetes, and hypertensive diseases of pregnancy.[47][48] Multifetal pregnancies also have worse fetal and neonatal outcomes than singleton pregnancies, with a significant increase in preterm birth and an associated increase in the risk of stillbirth (5-fold) and neonatal death (7-fold).[49][50] IVF providers limit multifetal pregnancies through several avenues, including low-dose stimulation regimens, close hormonal and follicular monitoring during stimulated cycles, and limiting the number of embryos transferred per cycle.[51][52] Once a multifetal gestation is diagnosed, appropriate counseling regarding the increased risks should be discussed with the patient, and the option of multifetal reduction, when appropriate, should be offered.[53]

IVF providers limit multifetal pregnancies through several avenues, including low-dose stimulation regimens, close hormonal and follicular monitoring during stimulated cycles, and limiting the number of embryos transferred per cycle.[51][52] Once a multifetal gestation is diagnosed, appropriate counseling regarding the increased risks should be discussed with the patient, and the option of multifetal reduction, when appropriate, should be offered.[53] Beyond multifetal gestation, singleton IVF pregnancies are also possibly associated with increased risks of various complications compared to naturally conceived singleton pregnancies. These complications include perinatal mortality, preterm delivery, low birth weight, cesarean delivery, placenta previa, placental abruption, and preeclampsia. These potential risks should be discussed with patients, but with caution, as the designs of existing studies limit data quality. Standardizing the tracking of outcomes of ART pregnancies to include these complications would improve the strength of evidence for or against these potentially elevated risks associated with IVF-conceived singleton pregnancies.[54][55] There is also limited evidence of a slightly increased risk of birth defects in pregnancies conceived via IVF, particularly with ICSI—though again, the quality of the data is low.[56][57] It is reasonable to offer ultrasonographic surveillance during IVF-conceived pregnancies, such as with fetal echocardiography, to screen for congenital anomalies.

Effective, patient-centered care with ART requires a coordinated, interprofessional approach involving physicians, advanced practitioners, nurses, pharmacists, and other allied health professionals. Each team member brings specialized skills and knowledge. Physicians and advanced practitioners lead the diagnostic evaluation and treatment planning, while nurses provide patient education, emotional support, and cycle coordination. Pharmacists ensure safe and accurate medication management. An andrologist with laboratory experience is essential for the evaluation and preparation of sperm for ART procedures, including semen analysis, sperm retrieval, and processing. Laboratory personnel execute precise technical procedures and perform vital hormone assays that inform clinical decision-making and ensure accurate timing of interventions. A clinician or technician skilled in gynecologic ultrasound plays a key role in follicular monitoring, endometrial assessment, and procedural guidance during egg retrieval and embryo transfer. The inclusion of a mental health professional with experience in fertility counseling supports patients and couples in managing the emotional, ethical, and psychological challenges associated with ART. Genetic counselors further enhance care by assessing hereditary risks, guiding decisions on preimplantation genetic testing, and supporting informed consent. Clear, respectful communication among team members is essential for aligning goals, minimizing errors, and enhancing patient safety. Ethical responsibilities include respecting patient autonomy, handling sensitive genetic and reproductive information with discretion, and ensuring equitable access to care. Strategies such as shared decision-making, standardized protocols, and regular case conferences improve team performance and clinical outcomes. Through collaborative practice and diligent care coordination, the interprofessional team can deliver high-quality, individualized ART services that prioritize both patient well-being and successful reproductive outcomes.
