Webb1. Generating Eggs: Ovaries Are the Female Gonads The ovaries are two almond-shaped structures that sit on either side of the uterus, connected to the uterine tubes. They produce oocytes (egg cells), as well as estrogen, progesterone, and other hormones. Egg cell production, or oogenesis, begins with the primordial follicles. Webbproduction, is in the initial stages of research in camelids. Maturation medium without supplementation of gonado-tropins results in low maturation rates of oocytes (Galli and Moor 1991; Wang et al. 2013). The in vitro maturation of oocytes in camelids is still incipient and remains a challenge to achieve the expected success (Wani 2024).
