Despite the multifaceted nature of infertility etiology, the impact of insufficient clearance of apoptotic cells on fertility has emerged as a focal point. Notably, the removal of apoptotic cells through phagocytosis in the female reproductive system has been a subject of extensive investigation in the field of infertility. Additionally, special functions performed by immune system cell types, such as macrophages and Sertoli cells, in the male reproductive system underscore their significance in spermatogenesis and the efferocytosis of apoptotic germ cells. Dysregulation of efferocytosis emerges as a critical factor contributing to reproductive challenges, such as low pregnancy rates, miscarriages, and implantation failures. Moreover, defective efferocytosis can lead to compromised implantation, recurrent miscarriages, and unsuccessful assisted reproductive procedures. This review article aims to provide a comprehensive overview of efferocytosis in the context of infertility.

Mangalarga Marchador breed mares from Muriaé - Brazil were divided into control, infectious endometritis, and post-breeding endometritis groups (<em>n</em> = 8/ group). Uterine fluid was collected via low-volume lavage and subjected to protein identification and relative abundance counting. From the 549 proteins detected, 279 were in the uterine fluid of mares from the three experimental groups. Thirteen proteins expressed mostly in healthy mares were associated with endometrial remodeling and early embryonic development. Albumin and uteroglobin presented higher relative abundance in healthy mares and animals with infectious endometritis. Infectious endometritis exhibited proteins related to innate immune and inflammatory responses, including annexin and glutathione S-transferase, and the highest abundance of lipocalins. Fifty-five proteins detected in mares with post-breeding endometritis showed signaling pathways and biological processes related to the innate immune response. These animals also presented the highest abundance of PIGR proteins, which promote IgA transport from plasma into the endometrial mucosa. In conclusion, our results revealed distinct protein profiles from the uterine fluid of mares with infections and post-breeding endometritis.

Immunohistochemical staining against CD24 and siglec-10 was performed and the expression of both markers was done with an immunoreactive score (IRS).

The expression of CD24 is significantly downregulated on the extravillous trophoblast and on Hofbauer cells of female acute covid placentas. In the contrary, CD24 is significantly upregulated on male post-covid-19 Hofbauer cells. The CD24-ligand siglec-10 is significantly downregulated in post-covid-19 Hofbauer cells independently of fetal sex, whereas it shows significant higher expression in control female Hofbauer cells.
