The female reproductive system is a complex system of external and internal organs that produce eggs that are necessary for reproduction. One egg is prepared for fertilization every month. If that egg isn't fertilized with sperm, you'll get your period — the result of your uterus shedding the...
The two ovaries contain hundreds of undeveloped female sex cells called egg cells or ova(the plural of ovum). Women have these cells in their bodies from birth - whereas men produce new sperm continually. 两个卵巢包含数百个未充分发育的雌性性细胞,这些细胞称为卵细胞或卵子。女性出生时就带有这些...
Oocytes are essential cells capable of developing into eggs, which can be matured either in vivo or in vitro. These cells progress through three distinct stages: primary oocytes, secondary oocytes and mature oocytes [126]. Primary oocytes, which are diploid cells in the initial stage of meiosis,...

(AMAB). These organs are both external and internal. Together, they make, store, and ejaculate sperm, which fertilizes eggs produced by the female reproductive system in order to begin a pregnancy. The male reproductive system also produces hormones such as testosterone, which play a key role...
Molecular Biology of the Female Reproductive Systemprovides a state-of-the-art review of local regulatory mechanisms that control reproductive processes. Stressing the interface of endocrinology, immunology, and cell biology, this book concentrates on the autocrine, paracrine, and endocrine systems that...
A Permutational Multivariate Analysis of Variance (PERMANOVA) [35] was performed to explore the significance of the presence of eggs and/or the female interaction with water, on the bacterial signatures associated with each group. Additionally, a pairwise PERMANOVA [36] based on the ASV abundance...
Here, we investigated the association between female reproductive factors and risk of all-cause and major causes of external deaths among middle-aged Japanese women. Methods and Materials Study population We used data of the Japan Public Health Center-based Prospective Study (JPHC Study), which is...
