Ovulation takes place on which day? Ovulation happens at day 14.
Reproductive Cycle – 28 Days
Day 0
Gonadotrophic Hormone, FSH and LH released by Anterior Pituitary Gland in the brain. These hormones cause the development of follicles in the ovarian cycle
Day 7
Granulosis cells are just cranking out estrogen and they actually start to produce two more hormones Progesterone, Inhibin.
Day 14
Estorgen levels are very high. Anterior Pituitary Glands releases less FSH and LH by sensing high Estrogen levels
Ovulation
Eggs pop out of the follicle here at day 14 in the process of ovulation. Menopause is nothing but the cessation of ovulation
Reproductive Cycle has 2 phases
Follicular Phase – First 14 days
Proliferative Phase – Day 7 to 14.
Secretory phase – Day 14 to 28.
Luteal Phase – Development phase of the corpus Luteum. Luteum means yellow body in latin. Corpus Luteum requires LH to stay alive.
Ovarian Cycle Graph
Hypothalamus releases a Hormone called Gonadotropin releasing hormone (GNRH). GNRH effects another part of the brain i.e, Anterior Pituitary
Anterior Pituitary in response to GNRH releases two hormones. One is Lutenizing Hormone (LH) and the other is Follicle Stimulating Hormone(FSH). LH and FSH primarily effect the male and female sex organs.
Zygote, sperm successfully meets an egg and create a cell called Zygote. It implants itself in the wall of the uterus. Gestation is the process of development of Fetus into the baby(9 months)
Ovarian Cycle lasts 28 days.
Each month an egg goes through the maturation process called the ovarian cycle. This cycle creates a secondary oocyte and that can be fertilised by sperm to result in a pregnancy. Primary oocytes that are destined to be ovulated will develop in the ovaries and ejected(Day 14) out of the ovary as a secondary oocyte to be picked up by fimbriae and swept into the uterine tube to hope for fertilisation
Basics of Egg(Oocytes) Development
Oogenesis, ovaries initially creates egg during gestation – When a baby girl is in their mother’s womb the baby girl’s entire egg supply will be created but will remain in an inactive state
Labor(Parturition) is the process of giving Birth.
