How many eggs are produced during a woman's reproductive lifetime?
From this time, no new eggs are produced. At birth, there are approximately 1 million eggs; and by the time of puberty, only about 300,000 remain. Of these, only 300 to 400 will be ovulated during a woman's reproductive lifetime. Fertility can drop as a woman ages due to decreasing number and quality of the remaining eggs.

In addition, the female reproductive system produces female sex hormones that maintain the reproductive cycle. During menopause, the female reproductive system gradually stops making the female hormones necessary for the reproductive cycle to work.
What is the pathway of the female reproductive system?
The Female Reproductive System. Pathway of the Ova (egg) The ova starts in the ovaries, (the female reproductive organ within the body). Then it goes to the fallopian tubes, which are tubes that connect the ovaries to the uterus. The uterus is where the fertilized egg develops into the fetus.

Female Reproductive System - Overview, Anatomy and Physiology
The female reproductive system consists of the primary as well as accessory sex organs. The primary sex organs in females are a pair of ovaries, which produce ova or egg and they also secrete female sex hormones like progesterone and estrogen.
Female Reproductive System: Explanation of the Function
Uterus (Hystera or Womb) Structure: The uterus is a hollow muscular organ of the female reproductive system and can be classified into three parts: body, fundus, and cervix. The uterus is also known as the womb and baby maker. The uterus can expand up to \(20\) times during pregnancy.
What happens to the ovaries during ovulation?
At ovulation, one of the ovaries releases an OVUM which begins its journey through where ?
What are the sacs that contain the ova?
caused by its contents—thousands of small sacs, called graafian follicles, or ovarian follicles, which contain the ova (sing., ovum).
What are the 3 walls of the uterus?
List the 3 walls of the uterus are made up of three layers: the endometrium, an inner (endo-) lining of uterine (metri/o) mucous membrane or tissue (-ium); the myometrium, a thick, muscular (my/o, myom/o) middle layer; and the perimetrium, or uterine serosa, an external (peri-) membranous layer.
How many glandular divisions are there in the breast?
Each breast contains 15 to 20 glandular divisions, called ___ or _____ which house milk-secreting cells.
Which hormone is released by the hypothalamus?
Gonadotropin-releasing hormone (GnRH) is a hormone made by the hypothalamus that causes the pituitary gland to release what 2 hormones?
When does the uterus lining begin to thicken?
Days 15 to 28 : With the ovum moving through the fallopian tubes for possible fertilization, the uterine lining again begins to prepare for pregnancy. LH triggers the corpus luteum to secrete an increased level of progesterone, and, in response, the uterine lining becomes thicker and develops a greater blood supply. When fertilization does not occur, secretions from the corpus luteum diminish, progesterone levels drop, endometrial cells die, and the reproductive cycle repeats with the onset of menstrual bleeding.
Which oocyte needs all of the nutrient-containing cytoplasm in case fertilization?
secondary oocyte needs all of the nutrient-containing cytoplasm in case fertilization
Can two follicles mature?
On very rare occasions, two follicles mature and rupture together. Conception and birth
When does ovulation occur?
Ovulation occurs when the oocyte has reached the ootid stage of development.
What is the process of an oocyte developing into a mature ovum?
Oogenesis is what an oocyte goes through as it develops into a mature ovum.
What is secondary oocyte?
Secondary Oocyte. Ootid. Ovum. Oocyte to Ovum to Zygote. An oocyte is an immature egg (an immature ovum). Oocytes develop to maturity from within a follicle. These follicles are found in the outside layer of the ovaries. During each reproductive cycle, several follicles begin to develop.
What is the stage of meiotic cell division?
Once a primary oocyte is affected by reproductive hormones, it completes Stage I of the meiotic cell division. This is known as oocyte maturation . At the end of this first stage of meiotic cell division, the cell splits into two separate cells: a small polar body and a large secondary oocyte.
How many oocytes are born in a cycle?
During each reproductive cycle, several follicles begin to develop. Typically, only one oocyte each cycle will become a mature egg and be ovulated from its follicle. This process is known as ovulation. A woman is born with all the oocytes she will ever have. This number decreases naturally with age.
What stage of meiotic cell division is oocyte maturation?
Once a primary oocyte is affected by reproductive hormones, it completes Stage I of the meiotic cell division. This is known as oocyte maturation .
Why is oocyte maturation not visible on ultrasound?
The oocyte maturation is also taking place, but oocyte maturation is not visible on ultrasound. This is why follicle growth is observed and not oocyte growth.
Where do oocytes go in the reproductive cycle?
The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
What are the internal organs of the reproductive system?
The internal reproductive organs include: Vagina: The vagina is a canal that joins the cervix (the lower part of uterus) to the outside of the body. It also is known as the birth canal. Uterus (womb): The uterus is a hollow, pear-shaped organ that is the home to a developing fetus.
What happens to the uterus after implantation?
Once in the uterus, the fertilized egg can implant into thickened uterine lining and continue to develop. If implantation does not take place, the uterine lining is shed as menstrual flow. In addition, the female reproductive system produces female sex hormones that maintain the reproductive cycle. During menopause, the female reproductive system ...
How does the egg get released?
As the egg is released (a process called ovulation) it is captured by finger-like projections on the end of the fallopian tubes (fimbriae). The fimbriae sweep the egg into the tube. For one to five days prior to ovulation, many women will notice an increase in egg white cervical mucus.
What happens to the female reproductive system during menopause?
During menopause, the female reproductive system gradually stops making the female hormones necessary for the reproductive cycle to work. At this point, menstrual cycles can become irregular and eventually stop. One year after menstrual cycles stop, the woman is considered to be menopausal. Cleveland Clinic is a non-profit academic medical center.
How long does it take for a woman to have a period?
Most women will have a menstrual period 10 to 16 days after ovulation. During this phase, the following events occur: The rise in estrogen from the dominant follicle triggers a surge in the amount of luteinizing hormone that is produced by the brain. This causes the dominant follicle to release its egg from the ovary.
How long does it take to get through your menstrual cycle?
The average menstrual cycle takes about 28 days and occurs in phases. These phases include:

- The ovulatory phase (ovulation) usually starts about 14 days after the follicular phase started, but this can vary. The ovulatory phase falls between the follicular phase and luteal phase. Most women will have a menstrual period 10 to 16 days after ovulation. During this phase, the following events occur: 1. The rise in estrogen from the dominant follicle triggers a surge in the amount o…
Luteal Phase
- The luteal phase begins right after ovulation and involves the following processes: 1. Once it releases its egg, the empty ovarian follicle develops into a new structure called the corpus luteum. 2. The corpus luteum secretes the hormones estrogen and progesterone.
