Sperm are streamlined through a process called spermiogenesis, during which they undergo morphological changes to develop into their mature form. This process involves the condensation of chromatin in the head, formation of the midpiece containing mitochondria for energy production, and elongation of the tail for motility.

The process by which a spermatid is converted into a motile sperm is called spermiogenesis. During spermiogenesis, structural changes occur that lead to the development of the tail and the formation of the acrosome, which is necessary for sperm motility and fertilization. This process involves extensive modifications to the spermatid's shape and organelles to enable it to swim and penetrate the egg for fertilization.

Spermiogenesis is the final stage of spermatogenesis in which haploid spermatids undergo extensive morphological changes to become mature, spermatozoa. During this process, the spermatids develop into elongated, mobile cells with a head, midpiece, and tail, which are essential for fertilization. Spermiogenesis involves chromatin condensation, acrosome formation, flagellum development, and reshaping of cellular organelles to produce highly specialized sperm cells.

Spermatogenesis is the process of sperm production in males that occurs in the seminiferous tubules of the testes. It is divided into three phases: proliferation, meiosis, and spermiogenesis. The process is regulated by hormones including follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone. FSH stimulates the production of sperm, LH triggers testosterone production, and testosterone is essential for spermatogenesis to occur.

In oogenesis after the first meiotic division one egg and one tiny cell are created. In Meiosis II the egg and three small cells are created. The three small cells are thrown away and the egg undergoes fertilization. In spermatogenesis after meiosis II four working sperms are ready to be used. There is only one usable cell created in oogenesis while in spermatogenesis four cells are created. the end result of oogenesis is only one viable cell while in sprematogenesis there are four.

Spermiogenesis is the final stage of spermatogenesis during which spermatids mature into spermatozoa. This process involves changes like condensing the nucleus, forming the acrosome cap, developing the flagellum, and shedding excess cytoplasm to create a streamlined sperm cell. It is crucial for producing functional sperm capable of fertilizing an egg.

The correct order of events during sperm production is spermatogonia undergo mitosis to form primary spermatocytes, primary spermatocytes undergo meiosis I to form secondary spermatocytes, secondary spermatocytes undergo meiosis II to form spermatids, and spermatids mature into sperm cells through spermiogenesis.
1 answer
The maturation process of sperm, known as spermiogenesis, involves the development of a sperm cell's head, midpiece, and tail in the testes. During maturation, sperm cells acquire the ability to swim and fertilize an egg. Once mature, sperm is released into the epididymis, where it gains motility and becomes capable of fertilizing an egg during sexual intercourse.

Spermatids are immature male germ cells that have undergone the first stage of spermatogenesis. They eventually develop into sperm cells through a process called spermiogenesis, where they undergo further maturation and differentiation. Spermatids have not yet developed the distinctive features of sperm cells, such as a tail for swimming.

Spermatogenesis is the process by which the male produces haploid gametes or sex cells (spermatazoa). Here is an explanation of spermatogenesis in humans.
* Spermatogenesis occurs in the seminiferous tubules of the testes in males. * Germinal epithelium gives rise to spermatagonia which are diploid (2n) and thus have 2 sets of chromosomes. * The spermatagonia then increase in size to form primary spermatocytes. * Primary spermatoctes undergo the first meiotic division and secondary spermatocytes are formed. * Secondary spermatocytes undergo another meiotic division to form 4 haploid spermatids.
* Spermatids must undergo a stage of metamorphosis before they become mature spermatazoa. This metamorphosis stage is called spermiogenesis. * During spermiogenesis, the spermatids undergo a change in shape, the cell elongates and the activity of the Golgi apparatus increases and there is production of many granules containing enzymes which are stored in the acrosome and are essential to the process of fertilisation. * One of the centrioles forms the basis from which the spermatazoa's flagellum (or tail) arises, which is required for the propulsion of sperm. * Mitochondria congregate in the neck region of the sperm and produce ATP by aerobic respiration. This ATP is needed for movement of the spermatazoa. * The nucleus also enlarges in this stage and cytoplasm is extruded into the Sertroli cells (Sertoli cells are associated with spermiogenesis). * The spermatazoa is now mature. Having said that, when newly ejaculated, sperm are not able to fertilise the female's oocyte - it is only after capacitation that the sperm is able to fertilise, and this takes place in the uterus and oviducts.

During spermatogenesis, diploid spermatogonium cells undergo mitosis to produce primary spermatocytes, which then undergo meiosis I to form secondary spermatocytes. These secondary spermatocytes then undergo meiosis II to form haploid spermatids. Finally, spermatids undergo spermiogenesis to differentiate into mature sperm cells.

During spermiogenesis, the round spermatids transform into mature sperm cells through a series of structural and functional changes. This includes the formation of the acrosome, condensation of the nucleus, development of the flagellum, and shedding of excess cytoplasm to streamline the sperm cell for its reproductive function. This process ultimately leads to the production of highly specialized and motile sperm cells capable of fertilizing an egg.

Sertoli cells extend inward from the periphery of the seminiferous tubule and provide nourishment to the spermatids as they undergo spermiogenesis. They create a protected microenvironment for the development of sperm, secrete necessary nutrients and hormones, and play a crucial role in maintaining the blood-testis barrier.

Spermiogenesis is tha final stage of the spermatogenesis which sees the maturation of the spermatid(results of division of spermatocyte-n). It is divided into 4-stages- 1.GOLGI PHASE ACROSOME( organelle that develops over the anterior half of the head and is the cap-like structure formed from the golgi appratus)- creates enzyme. At the other end, it develops a thickned mid-piece, where the mitocondria gathers and distil centriole begins to form AXONEME. SPERMATIDS DNA undergoes packing and become condensed. The DNA is packed first with specific nuclear basic protien which are subsequently replaced with PROTAMINE. 2. CAP PHASE 3.FORMATION OF TAIL one of the centriole of the cell elongates to become the tail of the sperm. A temporary structure called MANCHETTE exist in this elongation. During this phase the developing spermatozoa orient themselves so that their tail point toward the centre of the lumen, away from the epithelium. 5.MUTURATION PHASE.

In the case of man the meiosis is otherwise known as spermatogenesis, as a result of which 4 haploid sperms are formed. The sperms differ from the other somatic cells not only in the no. of chromosomes but cytoplasm is also very much reduced. they have acrosomes, tail etc. After reduction division modification of the sperm cells occur which is otherwise known as spermiogenesis. In male the spermatogenesis occur after puberty but then onwards continuous.
In the case of females it is known as oogenesis, as result they will be giving rise to only one ovary.(during the first and second meiotic division cell division is anisogamy and give unequal daughter cells in which the smaller ones released as polar bodies.) The ovary is rich in cytoplasm and have haploid no of chromosomes. In the case of human the first meiotic division of all possible primary oocyte takes place in the embryonic stage and second stage occur after puberty periodically one in a month
