Uterus and Cervix

Uterus and Cervix

The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs of...

Uterine Tubes

Uterine Tubes

The uterine or fallopian tubes function as the conduit through which oocytes travel from the ovaries to the uterus. Each fallopian tube measures approximately 10 to 13 cm long and is anatomically divided into the infundibulum, ampulla, isthmus, and interstitial part (or intramural segment). The infundibulum is characterized by its funnel shape and features extensions called fimbriae which reach towards the peritoneal cavity. These fimbriae play a critical role during ovulation as they extend...

Ovarian Cycle

Ovarian Cycle

The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...

Histology of the Uterus

Histology of the Uterus

The uterine wall consists of three histological layers: the perimetrium, myometrium, and endometrium. The outermost perimetrium is a thin, serous membrane connected with the broad ligament on the sides, which helps anchor the uterus in the pelvic cavity. The thickest layer, myometrium, is mainly made up of smooth muscle tissue bundles. Its contractions are vital in facilitating the expulsion of the uterine lining, fetus, and placenta during menstruation and childbirth.
The endometrium is the...

Summary

Uterus unicornis, a congenital condition where one uterine horn is underdeveloped or absent, was diagnosed in two American Paint Horses. This reproductive anomaly was confirmed via necropsy, revealing aplasia of the right uterine horn and oviduct.

Area of Science:

Veterinary Medicine
Equine Reproduction
Congenital Abnormalities

Background:

Reproductive examinations are crucial for assessing mare fertility.
Congenital reproductive abnormalities can impact breeding success.

Observation:

Two American Paint Horses presented with infertility or for pre-breeding evaluation.
Transrectal palpation and ultrasonography identified normal reproductive structures except for the absence of the right uterine horn in both mares.

Findings:

A diagnosis of uterus unicornis was made in one mare.
Necropsy confirmed unilateral aplasia of the right uterine horn and oviduct.

Implications:

Uterus unicornis can lead to infertility in mares.
Early diagnosis through reproductive exams is vital for equine reproductive management.
