Comparison of cost for conventional embryo transfer versus intracytoplasmic sperm injection.

Overview

• This study compares the costs associated with two reproductive technologies in horses: conventional embryo transfer (ET) and intracytoplasmic sperm injection (ICSI).
• The goal was to determine if one technique offers a cost advantage over the other by collecting and analyzing cost data from multiple clinics and breeding farms.

Introduction and Objective

• Conventional ET and ICSI are widely used reproductive methods that have different practical advantages.
• While clinical benefits and efficiencies have been studied, the relative cost of these procedures remains insufficiently explored.
• The study aimed to gather additional cost information from clinics nationwide to provide insight into the economic differences between ET and ICSI.

Methods

• A request for cost data was sent to 10 veterinary reproductive clinics across the United States, some of which performed only oocyte pickup (OPU) and others that performed both OPU and ICSI.
• Six clinics responded by providing data on at least 10 ICSI and 10 ET cases each, ensuring a representative sample of costs from diverse facilities.

Results

• Cost comparisons varied across the six clinics:
• In 3 of the 6 clinics, the cost of producing an embryo via ICSI was lower than via uterine flushing (traditional ET).
• One clinic reported approximately equal costs for both procedures.
• Two clinics showed that ICSI costs were more than double those of ET embryos.
• Key consideration mentioned is the number of embryos produced per OPU session. At facilities producing at least 2.5 embryos per OPU, the cost-effectiveness of ICSI improves due to the possibility of vitrifying (freezing) extra embryos for future transfers.

Conclusions and Implications

• The cost of generating embryos using ICSI can be comparable to that of conventional ET when factoring in:
• The additional embryos created by ICSI that can be cryopreserved and later transferred, spreading the cost over multiple attempts.
• The efficiency of the clinic in producing multiple embryos per OPU session.
• These factors mean cost alone should not be the sole deciding factor; clients need to evaluate all aspects including clinic performance, embryo production rates, and their specific reproductive goals.
• The study encourages informed decision-making tailored to the individual’s circumstances, as the best choice depends on multiple variables beyond just raw costs.
