What is ovulation? Ovulation is a phase in the Ovulation and your menstrual cycle The process of ovulation begins when your hypothalamus (a part of your brain) releases Between days six and 14 of your menstrual cycle, FSH causes follicles (small sacs of fluid in your ovaries that contain a developing egg) in one ovary to begin to mature. During days 10 to 14 of the cycle, only one of the developing follicles forms a fully mature egg. Around day 14 in the menstrual cycle, a sudden surge in LH causes the ovary to release this egg. This is ovulation. After ovulation, the hormone progesterone rises which helps prepare your uterus for Ovulation, conception and pregnancy Once ovulation occurs, your egg travels through your fallopian tube. It’s in your fallopian tube that your egg meets sperm for fertilization. If conception occurs (sperm fertilizes your egg), the fertilized egg travels down to your uterus. After about a week, the fertilized egg (now a blastocyst) attaches to the lining of your When does ovulation occur? In an average 28-day menstrual cycle, ovulation occurs about 14 days before the beginning of your next menstrual period. The exact timing varies — your cycle length may be longer or shorter. You may find it helpful to track your menstrual cycle using an app on your phone or a calendar. This can help you determine when ovulation is most likely to occur. Most people will have a period 14 to 16 days after ovulation, regardless of the length of their overall cycle. H...

Under the influence of follicle-stimulating hormone, several follicles begin to ripen, and the ovum with each begins to mature. The empty ruptured Graafian follicle becomes the corpus luteum and it begins to secrete progesterone and estrogen. About day 14, a surge of hormones cause the ovum to burst through the ovary.

Verywell / Gary Ferster What Are Antral Follicles? Theoretically, if you could know how many follicles are inside your ovaries, you could have an idea of how many eggs you have left. It is impossible to count how many follicles are in the ovaries because they are too small to be visualized. However, once a follicle reaches a certain stage, it can be seen via ultrasound. Follicles start off very, very small. All the follicles in the ovary start off as primordial follicles. A primordial follicle is just 25 micrometers—that's 0.025 millimeters. It is impossible to see with the naked eye, let alone on an ultrasound. Every day, primordial follicles are “awakened” by hormonal signals and start to mature. As long as they continue to survive and graduate to the next stage, they grow larger and larger. One of those stages is the tertiary stage. During this time, the follicle gains a fluid-filled cavity known as the antrum. Follicles with an antrum are referred to as antral follicles and measure between 2 and 10 mm in diameter. For some perspective, an antrum follicle that is now 5 mm is 200 times bigger than it was as a primordial follicle. Antrum follicles are visible with ultrasound. Research has found that the number of active antrum follicles on the ovaries correlates to the potential number of eggs left. You still can’t know how many follicles total there are, but when very few antral follicles are developing on the ovaries, ovarian reserves are likely to be low. Antral follic...

Ovulation is a process in which a mature egg is released from the ovary, pushed down the Fallopian tube and is available to be fertilized. Menstruation is the periodic discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. Menarche marks the beginning of the menstrual cycle while menopause is the end of menstrual cycle.

Overview What is anovulation? Anovulation happens when an egg (ovum) doesn’t release from your ovary during your How does ovulation work? Ovulation is the release of an egg (ovum) from your ovary. Ovulation is part of the menstrual cycle. On average, it happens on day 14 of a 28-day menstrual cycle. There are multiple hormones involved in ovulation. The process of ovulation begins when your hypothalamus (a part of your brain) releases Between days six and 14 of the menstrual cycle, FSH causes follicles (small sacs of fluid in the ovaries that contain a developing egg) in one ovary to begin to mature. During days 10 to 14 of the cycle, only one of the developing follicles forms a fully mature egg. Around day 14 in the menstrual cycle, a sudden surge in LH causes the ovary to release its egg. This is called ovulation. After ovulation, the egg begins its five-day journey through your fallopian tube to your uterus. As the egg travels through your fallopian tube, the level of progesterone, another hormone, in your body rises, which helps prepare your uterine lining for pregnancy. Can I menstruate without ovulating? In the medical world, However, you can still bleed — experience a “period” — without ovulating. This is known as abnormal uterine bleeding (AUB), or anovulatory bleeding. AUB is non-cyclic uterine bleeding that is irregular. Abnormal uterine bleeding is common — approximately one-third of people who have a uterus and are of child-bearing age experience it. Who does a...

Function What do your ovaries do? Your ovaries play a critical role in both menstruation and conception. They produce eggs for fertilization and they make the hormones Each of your ovaries has thousands of ovarian follicles. Ovarian follicles are small sacs in the ovaries that hold immature eggs. Each month, between days six and 14 of your menstrual cycle, The egg begins its travel through a narrow, hollow structure called the fallopian tube to the uterus. As the egg travels through the fallopian tube, the level of progesterone rises, which helps prepare the uterine lining for If you don't become pregnant that cycle, the egg disintegrates and gets reabsorbed by your body so menstruation can begin. What hormones do the ovaries produce? Your ovaries secrete estrogen and progesterone. These hormones play an important role in reproductive development and menstruation. Estrogen production is highest in the first half of your menstrual cycle before ovulation. Progesterone rises during the second half of your cycle to prepare your uterus for a fertilized egg (if conception occurs). Anatomy Where are the ovaries located? Your ovaries are on the right and left sides of the uterus in your lower abdomen. Your ovaries are held in place by several muscles and ligaments in your pelvis. The ovarian ligament connects your ovaries to your uterus; however, your uterus and ovaries don't touch. What do the ovaries look like? Your ovaries are oval-shaped and firm with a slight texture. They ra...

Term Meaning Oogonium immature germ cell that gives rise to female gamete Oocyte female gametocyte that divides to form egg cell Ovum egg cell, female gamete Follicle structure that encloses oocyte in a cavity, covered by granulosa cells Theca covering of follicle Antrum fluid-filled cavity in Graafian follicle Polar body small daughter cell formed by unequal cell division of oocyte I think the first part of the diagram is just showing that the 2n germ cell divides over and over, I don't think it's implying that 3 cells arise from mitosis. // // // Originally, replying, I misunderstood your question and thought you were asking about the primary oocyte meiosis and I wrote this whole description. While it's not what you were asking, I'm going to leave it below in case it answers someone else's question in the future. // // // The first meiotic division of an oogonium produces two cells: the primary oocyte and the first polar body. This first polar body basically is a way to discard half the DNA; most of the cytoplasm stays with the primary oocyte. Unlike regular meiosis (such as with spermatogenesis), the first polar body never divides, and instead degrades through atresia. Only the primary oocyte undergoes Meiosis II (but only in the presence of a sperm!). If this happens, a second polar body is produced (which is also degraded). So, from the initial oogonium, one egg cell (oocyte) is produced along with two polar bodies: 3 cells!
