Dr. Hazrat Bilal Malakandi. Understanding:. Spermatogenesis and oogenesis both involve mitosis, cell growth, two divisions of meiosis and differentiation.. Processes in spermatogenesis and oogenesis result in different numbers of gametes with different amounts of cytoplasm. Life Cycle. Life Cycle. – the development of an organism from fertilization to birth, growth, reproduction, and death.. The life cycle of every organism has these 4 main stages. 1. .

Infertility applies to couples who fail to achieve a pregnancy after 1 year of regular coitus without any contraception.. the Male. Spermatogenesis. Spermatogenesis goes on continuously from puberty to senescence along the entire length of the seminiferous tubules. Though a continuous process, spermatogenesis can be divided into three discrete phases: . Testis weighs about 20 GM and has volume of 15-25 ml, small testicle when the volume is less than 12 ml. The testicular volume could be measured by ultrasound using ellipsoid formula( . lenghth. *width*thickness*,52). Part 2. October 2021. Dr. Anna Haro. Westside HS. LEARNING Objectives .

Function:. Produce and deliver fertile sperm to the female reproductive tract. Produce the hormone Testosterone. Job:. Fertilize the female egg. Important Terms. Fibroelastic. Penis vs. Vascular Penis. In asexual reproduction, one individual produces offspring that are genetically identical to itself. These offspring are produced by mitosis. There are many invertebrates, including sea stars and sea anemones for example, that produce by asexual reproduction..
