B

Option (b) because the process of oogenesis in human female starts at the foetal stage not from puberty.

Wahid Khan

The process of formation of a mature female gamete is called oogenesis. Unlike sperm formation that starts at pubarty egg formation begins before birth. Primordial germ cells complete the proilferative stage or oogenesis in the early embryonal stage when million of gamete mother cells (oogonia) are formed within each faetal ovary, no more oogonia are formed and added after birth.

Wrong statement is b
because during ovulation immature ovum is released
it become secondary oocyte (mature ovum after entry of sperm )

Mahafuz Rahaman

B...( proliferation occurs during IUL not after puberty)

Aakash Mahale

This process starts in human male oogenesis is start from foetal stage not from at puberty.

Vijay Ratiwal
Aug 13, 2020
Secondary oocyte is released during MC that is imature or non-functional . after entry of sperm mature ova formed that is fictional ova

Santhana Priya

Correct answer is option.b. Oogonial cells start to proliferate and give rise to functional ova in regular cycle puberty onwards

During menstural cycle at 14th day estrogen level is high trigger ovum to release ova.

My insta id razeen_abdulrahim and option is b.....oogenedis start from embro stage..not from puberty stage

Subham Kumar Jena
Aug 06, 2020
Wrong statement is option 'B'.It is because immature ovum is released in secondary oocyte stage.

Manjima Ma
Aug 11, 2020
No more follicles are added after birth so oogonial cells cant proliferate

Leeman Rathor
Aug 12, 2020
B is right choice. because Germ cells after 1 time mitosis grown into oogonia and oogonia after 2 times meiosis( I and II) converted into a function ovum cell and degenerative polar body and .these all change occur at foetal stage not at puberty

Shushma Sree
Jul 25, 2020
Option B because oogonial cells proliferate through mitosis during 9 to 22nd week of embryonic development but not in puberty

Option B : Oogonial cells start to proliferate and give rise to functional ova in regular cycle puberty onwards.

Anita Saini

Bcz oogonial cells divide only in intra uterine life not at puberty

Saloni Rathod
Sep 07, 2020
Answer is b bcz primordial germ cell complete proliferative stage or oogenesis during embryonal
stage not on puberty

Guru Awate
May 08, 2020
Oogonial cells do not proliferate. they are suspended in meiotic-2 state. They only form 1 primary oocyte. option B would be the answer.

Dileep Ravula
Apr 27, 2020
The correct answer is b

Functional ova is released only after the fertilization not in regular menstrual cycle

Correct answer is b..becoz it is false statement

Bhat Raihana
Aug 17, 2020
The process of formation of mature female gamete is called oogenesis unlyk sperm formation that starts at puberty of egg formation begins before birth. Primordial germ cells complete the proliferative stage or oogenesis in the embryonal state when million of gamete mother cells r formed within each featal ovary no more oogonia r formed and added after birth. That's y correct option is (B)

Nishant Naik
Aug 11, 2020
Because M-2 is not completed until or unless sperm doo not enter the ovum cytoplasm

Because puberty ke aane ke pahle hi oogonial cells ka proliferation start ho jata h.. even meiosis 1st tak pahuch jata h.

Shruti Rajawat
Sep 01, 2020
Wrong statement is (b) because during ovulation immature ova is released and it become mature after the entry of sperm

Puja Kumari
Sep 26, 2020
B is thi right answer

Kruti Patel
Aug 16, 2020
Oogonial cells start to proliferate during feotal stage....that part is incorrect....but ova is produced at time of puberty only...so bcoz half part is incorrect that option is worg

Alga Benny
Sep 09, 2020
The process of formation of a mature female gamete is called oogenesis. unlike sperm formation that starts at puberty. egg formation begins before but promote the real germ cells complete the proliferate stage or oogenesis. in the early embryonic stage when billion of of gamut who gonio are formed within each faetal ovary. no more oogonia are formed and added after birth.

In case of female the process of ogenesis means ,formation of ovum, in its birth time is constant. ovum contenuesly releases but mature ovum releases at puberty

Anjali Sharma
Aug 16, 2020
Option b is the wrong statement because at 14th day estrogen triggers the ovum to release ova.

Oogonial cells start to proliferate and give rise to functional ova during embryonic stage

Yash Bhardwaj
Aug 09, 2020
The process of ooge esis start during the embryonic development when million of oogonia formed within each foetal ovary no more oogonia is added after birth so option b

Anjusha Babu
Nov 02, 2020
The process proliferation of oogonial cells starts in the female during its embryonic stage onwards and the maturation of spermatocytes in males takes place after puberty...don't get confused

Shruti Tripathi
Aug 20, 2020
Process of oogonial cell start in feral age not in puberty

Kyuki oogonial cells proluferate nhi hoti endometrium hoti h

Shreyansh Singh
Nov 10, 2020
Option A and B is wrong

Harsh Thagele
Aug 16, 2020
Answer -B is wrong statement because ovulation is female egg mature stage and pubility is reproductive stage

Sonal Mestry
Apr 13, 2020
Oogonial cells are primordial cells in human females which divide and form primary oocyte(2n) which further divide into secondary oocyte (n) which is divided by meiosis.

Swati Singh

Option b is correct.

Mk Creation

Sec. Oocyte comes in the form of MC
if sec. oocyte is fertiliz to sprem then ova is ready

Sudeshna Dutta
Sep 30, 2020
'B'- Oogenesis is initiated during the embryonic development stage when a couple of million gamete mother cells(Oogonia) are formed within each foetal ovary (about 3rd month of foetal ovary), no more Oogonia are formed and added after birth.

Manjunath Manju

There are many ova in female baby since from birth. It only mature at time of puberty

Sumedha Sarkar
Aug 02, 2020
Option -B is the right answer.

Medhavi Sharma
Sep 05, 2020
(B) option is bcz ova is functional when sperm is come in contact with sperm

Oogonial cells start to proliferate and give rise to functional ova in regular cycle puberty onwards

Nihal Dwivedi
Sep 17, 2020
B,, bcoz Oogonial cells start to proliferate during intra Embryonic life of a female baby

Sneha Suresh

B is the wrong statement
The gamete formation starts in female when the female is just an embryo, not from puberty onwards.No more oogonia are formed and added after birth.
ovulatory phase is followed by luteal phase where graffian follicle is transformed into corpus luteum which secretes progesterone.
sperms released from seminiferous tubules is poorly motile/non-motile.It only get vigourous motile power when it is temporarily stored in epididymis.
only fully matured ovum get released from ovary. ovum released from ovary in the form of secondary oocyte.ovam getvits maturity only when follicular development occurs around primary oocyte.The process of release of secondary oiche from ovary is termed as ovulation.so high levrl of estrogen trigger the ovulatory surge.

Tejas Tambakhe

Post-ovulatory phase is also known as the luteal phase. During this period, the follicle proper folds inward on itself and transform into the corpus luteum which is a steroidogenic cluster of cells that produces estrogen and progesterone. The action of progesterone increases the basal body temperature. 

So, the correct answer is "Progesterone level is high during the post-ovulatory phase of the menstrual cycle."

Kakubal Suma

This is not possible because at the menstrual cycle each oogonial cells get ruptured according to their turnover until it's fertilized

Unlike sperm formation, that starts at puberty ,egg formation begins before birth.Primordial germ cells complete the proliferative stage or oogenesis in the early embryonal stage when million of gamete mother cells (oogonia) are formed within each fetal ovary ,no more oogonia are formed or added after birth..

Ishika Verma
Aug 05, 2020
Oogenesis is initiated during the embryonic development stage when a couple of million gamete mother cells (oogonia) are formed within each fetal ovary (about third month of foetal ovary), no more oogonia are formed and added after birth.

Aasma Jii

Becoz it starts from embryo stage not from puberty

Sulthan Sulthan
Aug 14, 2020
Option b is correct because in human female every month ova is released .if it is not fertilized it may degenerates .at the foetal stage ova is not released in female .

Lalita Joshi
Jul 08, 2020
Answer is b because ogonial cells have formed the oocytes much before puberty

Aadya Kashalikar
Aug 10, 2020
B is the correct option as oogenesis starts at foetal stage of the human being
