The difference between spermatogenesis and oogenesis is mainly due to the following factors like the process, occurrence and the product formed after gametogenesis. Spermatogenesis is the production of sperms from spermatogonia in the seminiferous tubules of the testis in a male. Oogenesis is the production of the ovum from oogonia inside
Study with Quizlet and memorize flashcards containing terms like Which hormone is absolutely necessary for ovulation to occur? A) LH B) progesterone C) estrogen D) FSH, A human egg or sperm contains 23 pairs of chromosomes. (T/F), The cells that produce testosterone in the testis are called ________. A) spermatocytes B) sustentacular cells C) spermatogonia D) interstitial endocrine cells and more.
Although the process of spermatogenesis from type A spermatogonia to mature spermatozoa in mice is 35 days , nearly twice as long as necessary to differentiate into donor spermatozoa following transplantation . The reason for the difference of 35 days versus 2 months remains unclear, but the migration and colonization processes from the lumen
Male Reproductive System: Spermatogenesis. The production of sperm and eggs/ova (gametes) is a procedure called gametogenesis (spermatogenesis and oogenesis). Gametogenesis involves two rounds of meiotic cell division, in which one diploid cell gives rise to 4 haploid cells. This diagram shows the processes involved in spermatogenesis.
Introduction. Mammalian spermatogenesis requires proper establishment of the spermatogonial stem cell (SSC) pool, which resides within the seminiferous tubules of the testis and supports life-long germ cell development [].These progenitors give rise to all the differentiating germ cells, ranging from spermatogonia to spermatocytes to spermatids, and finally to mature spermatozoa.
The testis produces gametes through spermatogenesis and evolves rapidly at both the morphological and molecular level in mammals 1 - 6, probably owing to the evolutionary pressure on males to be reproductively successful 7. However, the molecular evolution of individual spermatogenic cell types across mammals remains largely uncharacterized.

To explore the function of Srsf10 in male fertility and spermatogenesis, we mated Srsf10 Floxed/Floxed (Srsf10 F/F) mice, in which the exon 3 (104 bps) was flanked by two loxP sites, with Vasa-Cre transgenic mice in which the Cre recombinase driven by a Vasa promoter is specifically expressed in germ cells as early as E15 (Gallardo et al., 2007; Figure 1A, Figure 1—figure supplement 1A and B).
