Reproductive performance in Macaca fascicularis following repeated laparoscopy

Area of Science:

• Reproductive biology
• Primate research
• Veterinary medicine

Background:

• Laparoscopy is a common diagnostic and surgical procedure in veterinary medicine.
• The effects of repeated laparoscopies on primate reproductive capacity are not well-documented.
• Macaca fascicularis is a widely used non-human primate model in biomedical research.

Purpose of the Study:

• To investigate the reproductive outcomes of Macaca fascicularis following repeated laparoscopies.
• To assess the safety and feasibility of conception and gestation after multiple laparoscopic procedures in this species.

Main Methods:

• Mating trials were conducted with 16 adult female Macaca fascicularis.
• Females had undergone a variable number of prior laparoscopies.
• Pregnancy and delivery outcomes were monitored.

Main Results:

• Eight of the 16 females conceived.
• Six of the eight pregnant females delivered live, full-term infants.
• These successful deliveries occurred in females who had experienced between 38 and 67 prior laparoscopies.

Conclusions:

• Repeated laparoscopies do not appear to compromise the reproductive capacity of Macaca fascicularis.
• Conception and successful gestation are achievable in females undergoing extensive laparoscopic procedures.
• These findings support the use of Macaca fascicularis in research involving repeated laparoscopic interventions.
