The gametophyte is a stage in the plants life cycle that undergoes alternation of generations.The primary job of gametophyte is Gamete production.
The physiology of gamete development is at the core of understanding reproductive medicine. In humans, oogenesis begins approximately 3weeks after fertilization in the developing fetus. Primordial germ cells (PGCs), arising from the yolk sac, migrate to the genital ridge. After arrival in the ...

6.3.2 Effects on fertility in humans In males, fertility difficulties are usually caused by poor semen quality and/or reproductive tract abnormalities. Endocrine-disrupting chemicals such as pesticides, phthalates, and PCBs have been implicated. Attention has focused on male semen quality and a potent...
The portion of the reproductive tract called the vagina is between the narrow uterine cervix and the outside of the body. In female humans there is a second opening where the urethra from the urinary bladder connects to the outside of the body. The urethral opening is normally separate from...
It is this latter endpoint of fertility that evaluates the relatively complicated process of gamete maturation and successful delivery via the ejaculate to complete the mating process (copulatory performance) leading to presumptive fertilization of the released oocyte in the female partner, and ...
Therefore, spermatogenesis and oogenesis take place in the presence of XY and XX sex chromosomes, respectively. When gonadal sex reversal occurs, however, the germ cell sex becomes discordant with the chromosomal sex. Both XX males and XY females in humans and XX males in mice are infertile ...
