Female Reproductive System: Changes In The Human Body

Female Reproductive System

The menstrual cycle is a natural recurring cycle of physiological (physical and psychological i.e., body and mind) changes in females of reproductive-age. The cyclic changes happen in the female reproductive system. First, in the ovaries, ovulation is marked by a breakdown in the wall of the follicle at the surface of the ovary. After ovulation, during the secretory phase, the theca cells and the granulosa cells in the mature follicle transform to produce significant amount of progesterone hormones into the blood and into the follicle, which is called a corpus luteum. The goal of this hormone production is to prepare and maintain the uterine lining for implantation in the event of fertilization. In the uterine tubes,

They are called fertility awareness tests. Some rely on only cycle length records called calendar-based methods. Some require monitoring one or more of 3 primary fertility signs -- basal body temperature, cervical mucus, and cervical position – known as symptoms-based methods. Urine test kit – known as ovulation predictor kits (OPKs) – can help, which detects the LH surge that occurs within 24 to 36 hours before ovulation. High-tech devices that interpret urinary test results, basal body temperatures, or changes in saliva are called fertility

Vital Systems: Just 10 days after implantation, the embryo’s heart begins to beat. The embryo starts receiving nourishment straight from the cells lining of the mother’s uterus. In 8 days, the cells of the growing embryo start to produce a hormone called human chorionic gonadotropin or hCG. This hCG hormone gets to the pregnant mother’s blood stream and urine almost immediately. It can be detected by most pregnancy tests. hCG interrupts the normal menstrual cycle and allows pregnancy to continue. [Hint: Among other pregnancy tests, hCG is commonly called as pregnancy hormone and its detection is common way to confirm pregnancy. In just 8 to 9 days after fertilization, doctors can confirm pregnancy by finding hCG in blood and urine. Some home pregnancy tests are available which check for hCG in urine. Also available computer aided pregnancy test, cleverly named as: p-Teq. This is a hi-tech USB Pregnancy Test Kit that requires woman to pee on a stick, similar to other home pregnancy tests; and then, uncap the other end which is a plug-in USB connector and insert it into one USB port of home computer and see the reading. Now new test kits are available to reveal how far along the pregnancy is. The Clearblue Advanced Pregnancy Test with Weeks Estimator, made available in 2013 reads: “Pregnant,” and a list 1-2, 2-3 or 3+ to indicate weeks of
